The Ride DC electric motors catalog divides into subcategories, identified by the external stator diameter, by the rotor length, in mm and by the presence of the Encoder.
In the subcategories there are different construction options. To support the choice of the best DC electric brushed motor, Ride shows interactive configurable data sheets.
Ride thinks in this way to the customers who need personalized DC electric motors, which can be anyway assembled trough consolidated and automatized processes, which guarantee competitive production costs and the reliability, indispensable in each application.
Between the offered permanent magnet DC motors, for each diameter it is possible to decide for the “standard” or for the “stronger” version: the difference comes from the rotor length. Longer is the rotor higher is the stall torque and the power that the DC brushed motor can reach. Among these products there is M77x40, stall torque from 5,10Nm to 1,27Nm, DC electric motors with brushes.
If requested, they can be equipped with EMC filter, usually made by two inductances and two capacitors.
In the inteactive technical datasheet it is possible to configurate the electric motor by selecting the preferred between the availabel options: motor shaft, filter, characteristic curve.
The interactive characteristic curve allows to select the required performances by selecting power voltage and no-load speed. Eventually it is possible to ask about further personalizations, like a special cables, simply by attaching in the request- form the relative documents.
The M77x40 electric motors are generally applied in linear actuators and in various automatisms.
Tobias Wölk, Product Manager Automation Technology & Active Components at reichelt elektronik, spoke about Europe’s key role in the production of the components of the future.
Let’s take a historical step back: the coronavirus crisis exposed the EU and U.S. dependence on Asian chipmakers. As demand for semiconductors exploded, production lines stopped, especially in the automotive industry. But today, chip production in Europe is to restart, and according to the European Chip Act, Europe’s share of semiconductor production is expected to increase to 20 percent by 2030.
Tobias Wölk, Product Manager Automation & Active Components di Reichelt Elektronik
The €43 billion European plan “In terms of financial architecture, the European Chips Act will mobilize 43 billion euros in public and private investment, including 3.3 billion from the EU budget, and as of June 2023, funding has been approved for about 100 European projects,” saysTobias Wölk, Product Manager Automation Technology & Active Components, reichelt elektronik. The manager stressed that Europe is only able to achieve true sovereignty in semiconductor manufacturing through a fully Europeanized value chain, from front-end to back-end manufacturing. “We need more manufacturing factories, but we also need regionalization of processing industries. Otherwise, we will continue to be vulnerable to disruptions in the global supply chain and our dependence on Asia will persist. A European semiconductor market can only be truly independent if all production steps are relocated to our Continent.”
Fragile supply chains To save costs, many large semiconductor manufacturers have decided to outsource back-end manufacturing to service providers who specialize in the Asian market. These outsourced vendors are known as Outsourced Semiconductor Assembly and Test Vendors (OSATs) and perform this work on behalf of large semiconductor companies. Nine of the world’s ten largest OSAT suppliers are located in the Asia-Pacific region (six in Taiwan, three in China). The complex manufacturing process makes global semiconductor supply chains particularly fragile in the face of a product that, on the other hand, is critical and increasingly crucial. Therefore, the EU’s Chip Act plan to strengthen European semiconductor production is obvious.
Forecast Simply relocating front-end production will not solve Europe’s dependence on semiconductors. “OSAT capacities must be increased to the same extent as front-end production. Otherwise, the localization of semiconductor production in Europe will remain incomplete and ineffective, as chips will still have to be sent abroad to be made ready for use,” Wölk explained. There is also a lack of adequate manpower to achieve such ambitious goals. According to calculations by PwC Strategy, there could be a shortage of about 350,000 workers by 2030 to meet the EU’s ambitious 20 percent target. “Another major bottleneck is the dependence on Chinese silicon production. Silicon, the most important raw material for microchips, is largely produced in China, a dependence that makes Europe vulnerable
Collaborations that express technological revolution and innovation are more and more frequent in the field of electric motors. In one of the latest partnerships, Analog Devices and Lotus are likely to be protagonists, committed to the implementation of a wireless battery management system (wBMS). With the elimination of 90% of the wiring equipping the car, the design freedom would increase and, at the same time, it would be possible to reduce by 15% the physical sizes of the battery pack and consequently the overall car weight. And all this without any kind of performance loss. The system is managed by a central unit that dialogues with the various battery modules by means of a wireless system.
Benefits should be mirrored on all future electric Lotus models, probably starting from the electric Type 132 SUV whose release on the market is expected in 2022.
«Lotus has a stellar reputation for building high-performance, long-lasting race and road vehicles, and many reach classic status,” said Roger Keen, General Manager of E-Mobility Group at Analog Devices. “Together, we’ve reimagined what is possible and developed a game-changer for the electric vehicle industry: a new ultralightweight powertrain architecture and a wireless battery management system that enables peak performance as well as a more sustainable environment for a healthier planet».
Finally, the floor is given to Richard Lively, Director, Propulsion and Chassis Engineering Lotus Cars: «We worked closely with Analog Devices to integrate wBMS into our new Lightweight Electric Vehicle Architecture (LEVA), which will be the basis for all future Lotus EVs. “The removal of the wire harness for wBMS ensures that Lotus can offer a lightweight solution that optimizes performance and is consistent with our brand of delivering powerful performance cars with exceptional handling».
Through the completion of the distribution system for MSFS motor starters for automation boards, Eatonmakes available for its customers a solution to power motor control and protection circuits enriched with numerous novelties, including a 125 A power supply module, new adapters for modular and box-type switches and a 5 A /24 VDC power supply.
The distribution system has been designed to offer a safe solution for the distribution inside the automation board and it is now equipped with a 125 A power supply module, hence the nominal capacity of the bus bars of the system itself. This allows using MSFS at its highest use current, permitting its full exploitation, while the previous limit was 80 A.
The system is positioned between the base solution, constituted by three-pole bus bar blocks, and the higher-level solution characterized by SASY60i distribution bus bar system, therefore defining a new intermediate standard in terms of cost, versatility and current values for automation systems.
Eaton, in the context of the widening of MSFS system, now proposes new adapters that extend the MSFS use also to utilities not strictly connected with the motor starter. This is possible because they allow connecting to the system both modular FAZ switches up to 63 A and the box-type NZM1 switch up to 125 A.
Meanwhile, in the suitable version (ROSF), also the new hybrid EMS2 starters (Electronic Motor Starter) can be coupled to the MSFS system.
Moreover, among the novelties the system completion provides for, there is also a three-phase 5 A /24 VDC power supply that, in most of automation applications, allows powering 24 VDC auxiliary circuits of the electric equipment of a machine without providing for further power supplies. Finally, the adapters offered until now for «PKZM0/PKE + soft-starter DS7» combinations extend their use possibility also to variable-speed DE1(1) starters up to 1.5 kW.
Alper produces polyester flexible heaters, electric and electronic circuits for the most different applications in several sectors. Among them, also the challenging automotive industry, to be meant in its widest scope, addressed by the company with a broad range of customized solutions where stand out those purposely studied for battery packs.
The mobility world is decisively looking at an electric-speaking future. In this context – no matter whether hybrid vehicles, as combination of endothermic and electric motors, or fully electric are at stake – battery packs undoubtedly play a protagonist role. An ambitious challenge accepted also by Alper, flexible heating specialist able to design and manufacture ultra-flat polyester resistances precisely used to make battery packs reliable and performing in time.
«It is known – the owner and general manager, Guido Alessi, explains – that the most diffused and used typologies of Lithium batteries for these applications, outside determinate temperature ranges, cannot always maintain optimal efficiencies.
Guido Alessi, owner and general manager of Alper
In temperature conditions below zero, for instance, they can feature some criticalities: to slow down the times needed for their recharge, to consume more energy, to supply less powerful pickups, and therefore to provide minor efficiency. Not fortuitously, for a long time now all manufacturers have attentively considered the so-called Thermal Management, fundamental issue to maintain battery packs at optimal temperatures to provide the best operational conditions».
Technical divisions, research and development departments of battery manufacturers, or directly automotive companies and electric vehicle producers, try then to solve such problems by implementing some devices.
«Concerning the solution of criticalities caused by cold and too low temperatures –Alessi adds – it is common practice to provide for the integration of adequate resistances directly among the cells of battery packs, or as external barrier that heats the chassis».
Another interesting solution allows instead exploiting the already existing liquid cooling system, suitable for regulating the functional heating of the battery at steady-state.
«In this case –Alessi highlights – it is possible to exploit the plates of the liquid cooling system, applying suitable heating elements and a simple 3-way valve. This allows by-passing the radiator entrusted with the standard, to exploit this mini-circuit that becomes the heating source for batteries».
Flexible polyester heating elements for electric batteries
More in detail, Alper ultra-flat resistances allow minimizing the necessary thickness of the heating element (from a minimum of 0.2 mm).
Usable in several application fields, like the broad diversified ambit of e-mobility, such resistances are produced by silk-screen printing, with an additive manufacturing technology, initially depositing silver tracks, for the electric current transport, and afterwards a layer of conductive and heating pastes.
Alper resistances are produced in the shape and sizes demanded by customers
Alper studies suitable Carbon pastes for any specific requirement
Similar to etched-foils, but much more reliable in terms of flexibility, they assure the highest efficiency levels at the service of low-temperature heat production. The constant research of new heating formulations has allowed the company to make the production capacity and the development of new design products, on customer’s precise specification, very versatile. The technology, unique of its kind, permits to reduce the costs of implementation and of eventual small modifications of the demanded powers (with a significant range of +/-20%) just modifying the composition of the conductive paste (unfeasible thing with etched-foil technology). All that allows implementing electric resistances with very high ohmic value, hardly feasible thing with other alternative technologies on films or with heating cables.
«Peculiarities and features –Alessi specifies – from which can benefit the battery packs designed for cars, trains, bicycles, motorcycles and any other electric vehicle, also used in industrial ambit such as forklifts or in shipbuilding. As many are the operational benefits for the same battery packs deriving from the use of ultra-flat flexible heating elements we design and manufacture: extension of the service life of the battery itself; increment of the good operation also at low temperature; faster recharge times, high temperature uniformity».
The added-value of the additive manufacturing technology
The use of highly thermo-stabilized polyester supports, properly treated for the adhesion of conductive silver and carbon pastes, confers high mechanical resistance and equal reliability in time to Alper heating elements (protected by dielectric films that allow passing the electric rigidity tests exceeding 3,750 V).
Alper production relies on high-precision printing machines able to assure with accuracy the sizes of the deposited tracks, thickness included
«Conductive pastes – specifies Alessi – as well as the conductive and resistive part that generates heat, are in-house studied, formulated and implemented, upon single specification and according to the application. An additive manufacturing technology, instead of subtractive, which then does not use chemical processes. In other words, our processes do not produce noxious industrial wastes, and even less polluting or toxic wastes to be disposed, with an undeniable environmental and ecologic benefit».
The heating element is printed on a very thin and flexible support and therefore it can be positioned in very narrow spaces, adapting it to curve surfaces, too. Various shapes of the element are possible, as it can have also holes or slots for applications needing them.
Worth highlighting that Alper carbon heating elements are made with very ductile conductive pastes, then they always assure great reliability even subjecting the heating circuit to constant movements and bending. Moreover, according to their composition, they allow silk-screen printing resistances that are not constant when the temperature changes but instead increase hand in hand with its rise.
«In practice –Alessi explains– this results in a decrease of the absorbed power proportionally to the high temperature level reached. This feature is very important from many points of view, safety included: resistances of this kind are in fact prearranged to reach the correct thermal balance with the environment».
On demand, Alper can supply a broad range of accessories, like for instance NTC probes, thermocouples, pt100, pt1000, fixed and adjustable thermostats and pockets for probe housing.
All resistances manufactured by Alper are subjected to the resistivity test
«Still for the automotive industry –Alessi adds– we produce also silk-screen printed antennas for the reception of digital radio stations, i.e. DAB, generally integrated in spoilers, in bumpers and wheel arcs of modern cars. Moreover, our ultra-flat carbon resistances are suitable for heating rear-view mirrors, some inner parts of cars, like seats, mats, roof as radiant heating of the car interior, arm rests and so on».
Total 100% quality
ISO 9001 and ISO 45001 certified, since its establishment conceived and organized as structure oriented to the process efficiency and the product quality, Alper has always paid great attention to its development cycle, granted by a skilled team. A group today consisting of twenty workers whose activity exploits advanced managerial systems and software, from design to production, from testing to logistics.
“The manufacturing process – ends Alessi – is constantly managed, coordinated and monitored in each phase, assuring high quality. The operational course provides for a total 100% control and not for a sampling test codification”.
Alper’s manufacturing process provides for in-line controls to assure in advance the compliance with technical and dimensional specifications demanded by customers or by regulations. Alper assesses and tests its production by 100%; this means they measure the ohmic value and carry out the dielectric rigidity test for each resistance
Uncompromised total quality, then, combined with certain production times. All that confers the company great efficiency and precision in deliveries, appreciated by direct and indirect customers, spread worldwide. Concerning this, it is worth underlining that Alper, with the precise target of providing higher and higher level service, for a couple of years now has been able to certify its products also as required by UL regulations for the American market.
The company in brief Established in 1992 as Research & Development Centre of Carbon conductive pastes with PTC effect, Alper developed, first in the world, a range of polyester heating elements with high power density, which has allowed its customers to be the first entering the USA market with innovative products. Building on the gained know-how, astride 2000s the company starts diversifying its product range. A winning choice that determines a constant growth up to being today, in Italy, a forefront manufacturing reality that produces flexible heating elements, made of polyester and other materials, for the most different applications and markets, with over half million units produced yearly.
Alper carries out its activity on the over 2,000 sq. m. of productive surface and headquarters at Cassola (VI)
A company that still today, in Italy, is unique of its kind, with a proposal of ultra-flat heating elements that allows satisfying the most different technological, productive and qualitative requirements. In addition to the household appliance industry, among the main supplied sectors stand out the general industry, Ho.Re.Ca, building and the rising automotive, for a turnover amounting to about 2.5 million Euros, half of which directly addressed abroad (from Germany to Spain, from England to France), considering that also 80% of the remaining part goes beyond the borders.
For battery housings, an ideal solutions for automated and integrated ultrafine cleaning with corrosion protection are Plasmatreat’s Openair-Plasma and PlasmaPlus.
Surface treatment with atmospheric plasma technology is the environmentally friendly and efficient alternative to conventional cleaning methods for companies. In applications such as in the automotive industry, electric mobility or electronics, Plasmatreat GmbH’s Openair-Plasma and PlasmaPlus replace wet chemical processes such as electroplating. The innovative plasma technology can be used to finely clean the surfaces of various metals and alloys, such as aluminum, and apply wafer-thin coatings to prepare them for further processing.
For a battery housing enclosed by a lid, it is necessary to equip it with a reliable anti-corrosion layer
Anti-corrosion protection When considering a battery housing enclosed by a lid, it is necessary to equip it with a reliable anti-corrosion layer. The requirements in this area are very high since batteries are often mounted on the floor of the vehicle. In this critical area, the battery is exposed to water spray, snow and road salt, which can be very aggressive to the battery. If moisture gets into the housing and cells, the functionality of the battery is compromised and, in the worst case, a fire can occur. That is why absolute sealing is a must. Liquid seals or, more recently, solid seals that allow the housing to be opened for repairs are used for this purpose. Plasma treatment promotes reliable sealing: after cleaning the sealing point with Openair-Plasma, the edge of the housing receives the PlasmaPlus AntiCorr coating for active corrosion protection. The AntiCorr coating, on the other hand, allows corrosion protection to be applied selectively, exactly where it is needed on the housing. The process is also much more environmentally friendly and, most importantly, dry, as it does not require chemical baths.
The AntiCorr coating allows corrosion protection to be applied selectively, exactly where it is needed on the housing.
For cleaning various metal alloys Plasma technology is based on a simple physical principle: the addition of energy changes the states of matter. When energy is added to a gas, such as air, it ionizes and enters the high-energy plasma state, known as the fourth state of matter. When plasma, with its high energy level, comes into contact with materials, their surface properties change, such as from hydrophobic to hydrophilic. Plasmatreat has made this effect technically usable on a large scale with normal compressed air and under atmospheric pressure conditions. It does this with atmospheric plasma equipment, the so-called Openair-Plasma, and has developed innovative solutions for numerous material problems, which have proven particularly effective in the processing of various metals and aluminum alloys, for example. Depending on the type of contamination on the metal surface or application, outdoor plasma systems use different process gases, such as compressed air or formation gas.
In the PlasmaPlus coating process a functionalized surface with defined properties is created by nanocoating.
Protection without wet chemistry Another process developed by Plasmatreat is used to treat metal substrates: the PlasmaPlus coating process. In this process, a functionalized surface with defined properties is created by nanocoating. A precursor is mixed with a carrier gas and forms a very thin layer on the surface. Plasmatreat uses various organic and inorganic groups for different precursors to treat metals and has developed highly effective PlasmaPlus coatings, including the PlasmaPlus AntiCorr process, which provides a high-performance anti-corrosion coating for housing gaskets and electronic components.
MAG MATE terminals, ICD slots with up to 4 contact points
Pioneer in the sector of electric connections, in the late Eighties TE Connectivity invented solutions to replace the old solder process technology for magnet wire connections. The company, multinational worth 14 billion dollars, supplies all-round solutions not only for the electric connection part but also for plastic insulation and assembling.
MAG-MATE connector with Multispring pin is a combination of two key technologies that eliminate the customer’s need to solder. It provides the ability to directly connect magnet wire to a Printed Circuit Board with no solder. Traditionally, the process is to solder magnet wire to a pin, assemble the PCB to the pin, and then solder the PCB to the pin. But now no more, thanks to this product that allows solderless magnet wire termination in the IDC (Insulation Displacement Connection) at the bottom and solderless PCB termination through press-fit Multispring pin on the top.
IDC technology
In the last 15 years, TE Connectivity has developed an optimal solution for the magnet wire termination. It is the family of TE MAG-MATE products for the magnet wire termination, used by many outstanding companies on a world scale in the production of motors and pumps. This product is based on the technology of Insulation Displacement Connection (IDC). For over 40 years, this IDC technology has proven to be an efficacious alternative to the wire stripping and soldering in thousands of applications.
«They are products –Ugo Aime specified – belonging to the “Appliances” business unit, but they can find all-round uses, for instance in the automotive, industrial and medical world, and in all various market applications where a magnet wire termination is demanded».
Currently, the market trend is focused on developing products that can be used in applications where space is a premium and design-to-cost is extremely important. Reducing components and material, keeping performance, is paramount for success. According to this strategy, we have developed a new proprietary concept with the support of of P.K. Senthil Kumar, Global Engineering Manager who works in our Bangalore branch, in India.This concept relates to an assembly for electrical devices that demand a compact and automated solution to transfer power from a power source.

In IDC system, terminals are provided on a metal band. Manufacturers insert terminals into a plastic cavity by using automatic or semi-automatic insertion equipment. The plastic cavity must use glass-filled material to have mechanical stability and can be molded in the customer’s coil or can be part of a separate component. This molded cavity has two slots on the opposite sides and an inlet chamfer on each slot. The magnet wire coming from the coil is pre-positioned in these two slots manually or through a winding tool. The wire rests on a support or on an “anvil” in the cavity.
The MAG-MATE terminal has two IDC slots with inlet chambers on the input points of slots. The terminal is positioned on the magnet wire in the plastic cavity and then inserted. Terminals “clean” the insulating film from the wire surface during the insertion. When the terminal has been definitively positioned, the wire is fixed between the two slots for the insulation displacement, to assure a safe and reliable termination. During this process, hermetically sealed contact points are created between the wire and the terminal. The opposite side walls of each slot of the terminal have a residual elastic energy that keeps the pressure constant on the wire, assuring a safe and reliable connection in the long term. Molded plastic slots fix the wire on each side of the metal terminal, assuring an anti-traction action.
Aluminum termination
The termination of the aluminum magnet wire use to represent a challenge for the IDC technology. Environmental and mechanical stresses cause in aluminum many more “creep” and “stress relaxation” phenomena than what with copper. Magnet wire manufacturers have succeeded in minimizing “creep” and “stress” phenomena. The studies carried out by TE indicate that motor manufacturers can shift from copper wires to aluminum wires and use standard insulation displacement terminals to eliminate the pre-stripping and soldering that need specialized manpower.
To assure that the connection process leaves the wire in an optimal region of the connector slot, technicians must indicate the optimal insertion depth for the single application.
Compact recently patented connection
«Currently, – explained us Ugo Aime, Product Manager Appliance of TE Connectivity – the market trend is focused on developing products that can be used in applications where space is a premium and design-to-cost is extremely important.

TrueActive™ Spool Valve (TASV) technology by Multimatic comes into play by revolutionizing the role of shock absorbers, transforming a passive suspension into a completely active system.
Multimatic TASV shock absorber is pioneer to integrate a unique liquid cooled 48V three-phase brushless electric motor to deliver supplemental force through a bespoke twin-lead ball screw and gearbox assembly into the damper shaft and to the vehicle.
Each actuator group of the TASV shock absorber receives direct controls from a controller of the vehicle dynamics that constantly optimizes the vehicle’s performances and passengers’ drive comfort, far beyond what is possible with adaptive and semi-adaptive suspensions. Alessandro Formenti, CEO at Vega Cylinders Company commented, complimenting on the choice of Ferrari Purosangue: “Imagine to drive your car without perceiving how you are moving. No longer feeling motor accelerations or pitching when cornering. It seems unbelievable, isn’t it? It seems a very distant choice from the sport driving. However it is the choice Ferrari made by installing some suspensions that annul drive sensations. These active suspensions have an electric 48V motor inside, connected with a special computer that reacts to the car’s stresses. Ferrari affirms this system helps fight load transfers and body movement, almost eliminating lateral body roll and shifting and distributing the load across the tyres. #Purosangue does not need anti-roll bars”.
It is called Tau, it is a Turin start-up in electric mobility and advanced materials and it collected 6.75 million Euros of funding for its innovative wire for electric motors, with the target of developing and implementing state-of-the-art technologies starting from 2022, able to accelerate the transition to the Factory of the Future for e-mobility chain manufacturers.
The round involved a variety of international investors, including a consortium of two Middle-Eastern sovereign wealth funds, the Russian Direct Investment Fund (RDIF) and a German investment manager.
The start-up is specialized in wires and components for electric motors, with applications in the automotive, energy and agriculture sectors, and it has developed the DryCycle technology, which defines a new standard of wire coating. Through the strict use of solvent-free polymers, the solution eliminates the release of noxious VOC and greenhouse gases, whereas a simplified production process minimizes the use of resources, decreasing the energy consumption and wastes. LILIT technology by Tau provides the quality control to assure the reliability of the polymeric insulation in the magnetic wire and in electric steel.
The vision of Tau consists in doubling the power of electric motors in a determinate size and the funds of the recent capital increase will be used precisely to accelerate the development of new products, to enlarge the range of high-performance wires and to increase the industrial production, to provide global manufacturers of electrical cars, buses, trucks, aircrafts and ships starting from the beginning of 2022.
The innovation promised by Infinitum Electric, Texan start-up, concerns the stator. It is implemented in printed circuit board on plastic support instead of with conventional iron. In this solution, the copper circuit is integrated in a single printed circuit board, to reduce the energy dispersions associated to the core, thus proving to be 60% lighter, up to 10% more efficient, more compact and even 25% cheaper than a standard electric motor. Moreover, the electric unit can reduce the torque ripple, minimizing noise while used, can integrate drives in the motor and install all sensors in the printed circuit board stator.
These novelties are expected to make the motor sturdier and more durable because the stator, which contains the entire coil, can boast a thermal expansion coefficient that remains homogeneous in all points. Technologies are protected by 5 patents already registered and other 11 under certification; recently, Infinitum Electric has accomplished the funding of 12.5 million dollars to produce the new motor on a world scale.
