The “Global electric motor market” report, a recent research by Allied Market Research, has revealed that the global electric motor market size was $96,967.9 million in 2017, and is projected to reach $136,496.1 million in 2025, growing at a CAGR of 4.5%.
The rise in demand for superior machine control in automotive industry, owing to the high efficiency of AC synchronous motors fuels the electric motor market growth.
The regulations such as Minimum Energy Performance Standards (MEPS), drives the growth of energy efficient electric motors market across the world.
The material handling systems serve as the key consumers of fractional horsepower (FHP) motors, thus boosting their demand across the globe. Moreover, the adoption of motors ranging 21-60 V in HVAC sectors, owing to the heat dissipation, are anticipated to exhibit high demand for these motors in the coming years. However, the industrial motors with high power rating generate substantial vibration, strain, and heating during their performance, which could potentially have profound influence over electronic components, and result in their malfunction. In addition, lack of awareness of benefits associated with smart motors among small and medium enterprise owners for various applications is expected to hinder the growth of the electric motor market during the forecast period.
The global electric motors have widespread demand in North America, followed by Asia-Pacific, and Europe. The highest share of the North America market is attributed to the increase in demand in AC motors in automotive sectors.
The global electric motor market is also witnessing considerable growth in the emerging markets such as India, China, and others. This growth is attributable to the development of the automotive, machinery, and fan & ventilation industries and high demand for better energy-efficient electric pumps.
Increase in demand for medium to large voltage motors, particularly in emerging wind power markets, is further expected to fuel the market growth. However, rise in use of other energy-efficient motors as an alternative to conventional motors is anticipated to hinder the market growth. North America is witnessing the highest demand for AC synchronous motors, followed by Asia-Pacific, Europe, and LAMEA. The highest share of the North America market is attributable to increase in demand for conveyers in the industrial machinery segment. THE REPORT

Cruise and General Motors announced that they have joined forces with Honda to pursue the shared goal of transforming mobility through the large-scale deployment of autonomous vehicle technology. Honda will work jointly with Cruise and General Motors to fund and develop a purpose-built autonomous vehicle for Cruise that can serve a wide variety of use cases and be manufactured at high volume for global deployment. In addition, Cruise and General Motors and Honda will explore global opportunities for commercial deployment of the Cruise network.
Honda will contribute approximately $2 billion over 12 years to these initiatives, which, together with a $750 million equity investment in #cruise, brings its total commitment to the project to $2.75 billion.
“This is the logical next step in General Motors and Honda’s relationship, given our joint work on electric vehicles, and our close integration with Cruise,” said General Motors Chairman and Ceo Mary Barra. “Together, we can provide Cruisewith the world’s best design, engineering and manufacturing expertise, and global reach to establish them as the leader in autonomous vehicle technology – while they move to deploy self-driving vehicles at scale.”
After outlining the product and support proposal for the electric motor world in automotive and/or appliance ambit, we have asked interviewed companies their point of view on possible future scenarios/technological trends.
“The most felt requirements in the sheet metal forming market, especially for the automotive sector– highlights Michele Archenti, Sales and Marketing Manager AIDA Europe – are, and will increasingly be, more control and more automation of manufacturing processes. The revolution called Industry 4.0, aimed at boosting innovation in industrial field, mainly focuses on the theme of the integration and the connection of industrial machines to the corporate net. Concerning this, the most important novelty at which we are working, concerns the use of Machine Learning algorithms to offer advanced preventive maintenance solutions able to help us in preserving the most important good of each customer: manufacturing continuity”.
Precisely according to this vision, AIDA group has already developed and implemented its complete solution for the data processing (through cloud computing): AiCARE (AIDA Information Care System). It can provide advanced information about the production and maintenance state of each single press, such as, just to make an example, manufacturing data, data on energy consumptions, on the oil quality or the operational temperature, or data regarding the use degree of each single element that composes the press.
“The AiCARE system– adds Archenti – has been conceived to be integrated on all of our press typologies but, at the same time, it can be seen as an external device to be implemented on already installed presses”.
Therefore, it is a solution “that can be retrofitted” on the machine fleet already installed. Not only AIDA presses are concerned but the installation is possible also on other manufacturers’ presses.
Concerning possible future trends and scenarios, Bluergo thinks that the electric motor evolution as traction, in automotive ambit, will have its course, with times a bit delayed compared to what imaginable just some years ago. Owing to different reasons, as Andrea Cusinato, Sales Department Bluergo, specified: “Without prejudice to the environmental and performance benefits, there are some criticalities and difficulties not completely solved, I think. I am referring, for instance, to an infrastructure and to a grid energy not ready to transpose “big numbers”. Likewise, the vehicle cost for end-users, even if constantly adapted, unfortunately does not seem affordable for today’s users of small subcompacts, yet. In other words, times are not mature for a mass diffusion, yet. From our point of view, we believe instead the petrol/methane, diesel/methane conversion technology is more within reach”.
In the last biennium, the company has been very active and committed to the latter context, with the supply of tailored electromagnetic components. “If, instead, with electric motor – specifies Cusinato – we mean not only the traction, it is indisputable it is in constant evolution. Especially if we refer to brushless motors, which nowadays represent the almost totality of motions and drives equipping a car”.
Bluergo has been committed to this ambit for years and it is investing huge resources in it. A strongly growing market that, today, absorbs a significant percentage of the corporate production.
“Referring to the Home Appliance sector – adds Cusinato – it is following the same evolutionary course, with the replacement of standard single-phase motors with brushless technology. However, also in this case the cost aspect hinders its mass diffusion”.

Cagnoni confirms the electric motor world is living a constant growth in the automotive and appliance sectors.
“Nevertheless – specifies the managing director Giordano Sorci – the brushless motor is rapidly spreading, widening applicative opportunities. Today, also for this reason, our customers, I would say about 10% of them, are diversifying productions by introducing the brushless technology, too. However, not all sectors can avail themselves of these typologies, therefore I believe the conventional brushed motor still has several decades of career in front”.

Automation is increasingly shifting towards motors produced in smaller yearly quantities. This is the point of view of Demathat, by voice of the owner Mr Cesare Librici, confirms how such datum influences the technological requisites demanded for its plants.
“If previously – states the engineer Librici – typically one of our automated machines was required by one of our customers that had productions of 500,000, one million of parts yearly, today we have dropped by one order of magnitude. This means the demand for the part of our competence is oriented towards a fully automatic process. And no longer semi-automatic or even manual. This interpretation concerns both the automotive and the industrial world. More complex is instead interpreting trends and scenarios for the appliance industry that, still according to our point of view, does not seem to show particular interest in investments in new products today”.
Clear and precise also the vision of Demak about possible future scenarios/technological trends where the electric motor will be the protagonist.
“Certainly electrification – states the Technical Sales Manager, Massimiliano Balboni – already in course for some years, will become a “vital” and decisive step for all OEMs and for the whole chain. Especially, however, for companies that will mandatorily need to integrate into their manufacturing cycle technologies with zero or minimal impact on the environment. Therefore, it is undoubted that companies themselves, besides investing in R&D activities for the development of electric traction with more autonomy, will be also requested to provide for investing in “Eco-Friendly” technologies, which can grant, at the same time, excellent-level performances of the electric motor and of other components”.

The future of automotive is electric. Sergio Iori, president of EuroGroup, has no doubt.
“The automotive industry– he affirms – is getting ready for the increment of the demand for electric vehicles. We cannot establish with certain responses, yet, whether and when the car with thermal motor will end, whether and how much the hybrid traction will still develop. However, it is certain the activity that today concerns the productive developments of electric vehicles is, according to many, a real Tsunami and, anyway, an epochal turning point”.

Christian Grob, Supervisory Board Chairman of GROB-WERKE, underlines how it is important to remind the e-mobility is still a relatively new concept for the automotive field.
“All market players– he declares – must adapt their approach. Working in strict collaboration with primary sector brands, it was immediately clear that there was a big need of mass production installations in the automotive industry, with particular attention to key components, that is to say the electric motor and battery components. Currently, designs are created and developed only through a strict consulting with the automotive industry. Even if markets are reacting to this with different speeds, Grob sales have already suited new technologies worldwide”.

Wide, efficacious and detailed is the reflection expressed by Inarca on possible future scenarios/technological trends, implemented in automotive and appliance ambit.
“In automotive ambit – highlights the sale manager Alessandro Rocchi – the increasingly extended demand for components managed by electronics makes the need of connecting mechanical parts to boards or circuits more and more frequent. This will lead to an ever-rising diffusion of the mechanical cold junction, much more efficient than welding, due to both the minor problems in junction phase and the possibility of replacing parts quickly. Consequently, the market trend is favourable for us, since we have invested for years in Crimp and IDC technologies, where today we can say we are technological leaders. Moreover, the more and more diffused presence of aluminium, instead of copper, as material used for electric motors’ windings works for us, as we have developed for years more and more efficient solutions for applications of this kind”.
Referring to the appliance world, Rocchi points out that the technological evolution of the household appliance sector determines an increasingly massive presence of electronics, which exponentially increases the number of connections for each single device and produces more and more complex geometries.
“The successive step – he adds – will be the massive diffusion of iOt, internet of things, which will further boost this phenomenon».
In this context, Inarca proposes itself as technological reference partner: for years, in fact, it has developed a line of specific solutions for the mechanical cold junction (both Crimp and IDC), which allow utmost efficiency in application phase.

In the opinion of Enzo Montani from Piciesse, certainly last years’ data highlight a strong growth of the innovative mobility and motion: “Beyond the mobility in the strict sense – he adds– the sector dedicated to the terrestrial motion and to the introduction and refinement of more and more technological and attentive means is increasingly protagonist. We are referring to trains for electrified lines, to hybrid/electric cars, to e-bikes, to electric scooters, to segways and to hoverboards. Besides, aware of facing a more and more diffused electric production, probably the need of developing smart flexible grids, able to manage peaks and to distribute energy safely, will rise. This will highlight the importance of the so-called smart grids and will gradually require efficient and complete management and communication systems of grids themselves”.
More and more refined technology for more efficient and safer systems. This is the synthesis by Rodolfo Risatti, owner of Risatti Instruments: “We believe – he affirms – in the future, technology can nothing but refine and reach specialized levels that will grant more efficient and safer systems. According to this perspective, we daresay the technologized automated drive will be used on all transport means”.

The point of view of Samac reveals how the next evolution, already partly in course, will reside in the shift from electrification to electronification. A step that, for the company, will make the critical components of complex systems – like for instance the motor in a car but also an electric axis in machines – become independent in the management of their operation and maintenance parameters.

Concerning future trends and scenarios, Zoppas Industries Heating Element Technologies highlights a first big discriminant among hybrid, plug-in and full-electric vehicles. Moreover, car typologies will be subdivided by autonomy range and by market target, luxury and performances, too. The company’s hypothesis envisages a more and more fragmented market, to meet the manifold requirements that, in combination with the new trends of Megacities and of connectivity, will be defined by end-users. Concerning heating, the macro-typologies that Zoppas Industries Heating Element Technologies glimpses in the next future are the following: air heating for small cars for city-urban use; heating through fluid circuit loops for the cars of the average range; heating by heat pump for “premium” cars; heating through radiant surfaces as possible long-term evolution in the car interior.
What proposal of products and technological support for the electric motor world in automotive and/or appliance ambit?
World reference reality in the production of high-speed presses, automations and complete systems for the sheet metal forming, AIDA, for several time now, has already invested part of its research capability in the development of specific solutions for the production of electric motors. Today the fruit of this activity allows the company to offer two product lines fully dedicated to rolling: AIDA HMX Series and AIDA MSP Series.
Michele Archenti, Sales and Marketing Manager AIDA Europe
“They are products– confirms Michele Archenti, Sales and Marketing Manager AIDA Europe – the market already highly appreciates. To the extent that we can boast hundreds of installations in leader players’ production plants”.
AIDA MSP presses (Multi-Suspension Points Presses) allow producing high precision and high efficiency motors such as EV motors, HEV motors and energy-efficient home appliances motors.
Executions that are highly suitable for the production of parts characterized by thicknesses under 0.2 mm.
“Such presses – adds Archenti – stand out for notable dynamic precision, due to both the compact design, to the architecture consisting in in-line multi-suspension points, to the native Aim function (i.e. Adjust In Motion) and finally to the balance reached between the high stiffness and the wide plan surface. Indispensable prerogative, the latter, to house tools with the number of stages needed for the production of high-efficiency motors”.

“In this survey– states Sergio Iori, president of EuroGroup – our Group plays an important role, offering more and more efficient stators/rotors for electric motors to the market. Efficiency that, in the specific case of electric vehicles, results in more autonomy of car driving distance”.
Sergio Iori, President of EuroGroup
In the stator/rotor, this needs not only a use of steels with increasingly high magnetic and permeability features but also thicknesses that from standard 0.5-0.65 mm decrease to 0.30-0.20 mm (and someone already uses 0.10 mm), besides stricter geometrical tolerances owing to heat and noise reduction reasons.
“Our response/offer to the market– adds Iori – provides for several solutions: progressive blanking dies able to process these new materials, assuring the final characteristics demanded; assembling systems of single stator/rotor laminations; accessory operations on the motor, like magnet and shaft insertion and successive machining and balancing”.
In particular, the assembling systems of single stator/rotor laminations provide for various solutions: gluing (Glue Fastec); packing (Corpack/Zip) during the blanking with compensation by rotation of laminations, even with 0.20 mm thickness (granting a stacking-factor in line with the motor requirements); welding of stator/ rotor through laser/Tig/Mig technology.
“In line with the requisites of Industry 4.0 – adds Iori – we can assure the total traceability of our whole production. All that in compliance with quality procedures established by IATF regulations”.
This industrial approach is adopted by EuroGroup also for stators/rotors for the Home Appliances sector, to the end of a constant technical improvement, aimed at increasing the efficiencies of the electric motor for this type of applications.

This is Part 2 of a three-part article
Read Part 1: Focus: electric motor, current and future scenarios
Read Part 3: Future scenarios and technological trends
The language of the future is increasingly “electric-oriented”, not only in automotive but also in appliance ambit and in the most different applicative sectors. Ferment that involves the entire manufacturing chain, with companies committed to providing innovation that keeps pace with a more and more challenging and competitive market. What is their product and service proposal, and their point of view on possible evolutions?
Increasingly spread in all application types, electric motors find all-round use due to their well-known peculiarities and operational technical specifications. In this context, undoubted protagonists and big users are, among the others, the automotive and the household appliance industry. Sectors that benefit from a complex manufacturing chain that must keep pace with technological innovation to be able to provide solutions in a more and more complex and competitive market. Manufacturing companies that, according to their specialization, supply components, machining lines and plants, besides support and consulting of absolute technical level. We have interviewed some of them. A representative panel (without the presumption of being exhaustive on the topic) to highlight their proposal of competences and solutions, besides trying to outline the possible future scenarios and trends.
Waberer’s (vehicle operator in international full truckload transportation in Europe) is willing to test and is open to participate in the introduction of Tesla’s e-trucks in Europe. Also, as the firsts from Europe, Waberer’s tested the Tesla Semi e-truck designed for long-distance transportation. Waberer’s and Paccar Group (supplier of Daf trucks) are discussing the testing and introduction of electric and driverless vehicles under development. “We at Waberer’s are committed to continuous innovation and seize every opportunity participate in our partners’ R&D and innovation programs. Electric and driverless truck developments may significantly reduce the environmental impact of road transportation and have a favourable effect on the cost side at the same time. We see a great opportunity in developments concerning logistic infrastructure. In fact, we have effectively implemented several digital innovations in our operations”, said Ferenc Lajkó, Ceo of Waberer’s.
For the development and the diffusion of vehicles equipped with autonomous driving systems, the safety matter is obviously central. The results of the research “Global Automotive Consumer study” by Deloitte have highlighted, for instance, that European consumers feel safer on an autonomous-driving car produced by manufacturers of the automotive industry than in cars proposed by hi-tech companies, thus revealing people’s trend to perceive brands already known and “tested” as more reliable. The safety of autonomous driving systems is a topic to which TÜV SÜD (independent body that operates in certification, inspection, testing, tests and training) has dedicated the “Driver Assistance Systems Conference”, held in Munich, in Germany, with the participation of over 200 engineers. Among the themes treated – as underlined Pietro Vergani, Business Unit Manager Consumer Product of TÜV Italia – they debated also the simulation issue, which will play a fundamental role in the future test and homologation activities. «Using these methods – he stated – test structures can assess daily up to 50 million scenarios: an unfeasible enterprise with physical tests on vehicles». Another subject discussed in Munich concerned the electronics of cars and these systems’ capability of imitating human behaviour.

The engineers attending the conference mentioned “neural networks”, i.e. a sort of artificial nervous system that allows machines or computers to learn autonomously, in compliance with the artificial intelligence vision. Besides, at the conference they presented IMAGinE project, which develops advanced driving assistance systems able to introduce support actions to the autonomous driving, too. Concerning instead platforms, the representative of an automotive company attending the conference underlined that “non-exclusive” ones will become more common in the future, they will be at disposal of various automotive companies and this will result in a reduction of costs, meanwhile making available a growing number of vehicles. Finally, in the opinion of Pietro Vergani, innovations also in car homologation methods will have to correspond to technological innovations. «We have analysed thoroughly new possible homologation approaches for autonomous-driving cars – explained Vergani – and we have inferred that virtual homologation methods, based on test simulation of virtual vehicles, are already reality and transposed by the legislation in course, even if not extensively and for dedicated approval ambits, like for instance the simulation of mechanical stresses on frames or underrun bars. Such methods, and the relative technical validations, are steeply rising and they will be the control basis for the vehicles of the next future».
This zero-emissions plane is expected to make a run for the record books with a target speed of 300+ MPH (480+ KMH). The 24ft-wide carbon-fibre aeroplane is being constructed by a 20-man team led by Rolls-Royce at a hangar the Staverton site.
The company hopes the plane will hit a world-beating top speed of more than 300mph when it takes to the skies over the UK in the first half of next year. The current record is 213mph, it was set last year by German-built Extra Aircraft 330LD, powered by a Siemens electric motor.
Inside a bustling hangar bay at the far end of Gloucestershire airport in South West England, a team of British engineers, designers, and data specialists recruited from across Rolls-Royce and beyond have set out to make history. They’re building a high-performance electric aeroplane unlike anything the world has ever seen. Scheduled to take to the skies over Great Britain in 2020, the aircraft will reach a speed of 300 mph – and quite likely more – making it the fastest all-electric plane in history.
This run for the record books is no stunt. It’s part of a Rolls-Royce initiative called ACCEL – short for “Accelerating the Electrification of Flight” – that’s intended to pioneer a third wave of aviation in support of Rolls-Royce’s strategy to champion electrification.

New IDTechEx report, “Electric Vehicles in China 2019-2029” shows that the penetration in China of electric buses is more impressive than electric cars. Like most other new products, electric vehicles sell in an S curve of a slow start with over supply. Then comes fastest growth with supply sometimes unable to keep up with demand then comes saturation. Take pure electric buses as an example. Here China rapidly deployed 400,000, 99% of the total number in the world, then it collapsed subsidies causing a collapse in deliveries and sadly it mainly makes smoking buses again.
The rest of the world is beginning to compensate. For example, recently Qbuzz in the Netherlands has ordered 159 pure electric buses, Helsingborg Sweden 76, Brussels Airport 30 and London 68 pure electric double deckers. Cities across the UK recently placed a total of 263 orders for zero-emission buses. Warsaw will order 130 pure electric buses for delivery by 2021. Kazakhstan is expecting 700 electric buses and Azerbaijan another 500 over the next three years. However, India has the largest potential, with a government plan for an initial 10,000 pure electric buses replacing some of the 1.6 million registered buses there, all of which must go, says the government, sensitive to the deaths they cause. The Indian state of Uttarakhand has ordered 500 electric buses. Now India is responsible for about 25% of the pure electric bus orders outside China. The Chinese – mainly BYD – are behind much of the supply but by no means all. Tata Motors in India has orders from six cities for a total of 255 pure electric buses. Large subsidies are an essential part of the take-off everywhere, China being at the top of the growth curve and everywhere else at the fast growth part, though China may see another S curve based on free market demands when pure electric has price parity.
Battery costs have been a primary impediment. However, in an interesting development, busy bus routes are seeing progress to less or no battery. Eight countries have ten-second charging supercapacitor large buses now and non-stop top-up charging in many forms has arrived from solar bodywork to intermittent catenary, rails, coils in the road. Top-up, including stationary forms with gantries etc at bus stops, typically leads to 80% less battery and this and the reduction in battery prices has led to some projections of the battery being a mere 6% of bus cost in ten years’ time. For more on all that see the IDTechEx Research report, “Energy Storage for Electric Buses and Trucks 2019-2029”. That will hasten the day when the up-front price of pure-electric buses is at parity with diesel. The rising cost of diesel powertrains also helps. Consider the extra cost of diesel fume reduction measures such as 48V mild hybridisation and the cost of adding equipment to treat emissions. IDTechEx currently projects price parity around 2030 for large buses but the future can come early.
However, the industrial motors with high power rating generate substantial vibration, strain, and heating during their performance, which could potentially have profound influence over electronic components, and result in their malfunction. In addition, lack of awareness of benefits associated with smart motors among small and medium enterprise owners for various applications is expected to hinder the growth of the electric motor market during the forecast period.
Based on output power, it is classified into integral horsepower (IHP) output, and fractional horsepower (FHP) output. By voltage range, the market is categorized into 9 V & below, 10-20 V, 21-60 V, and 60 V & above. In 2017, the 60 V & above motor segments held the largest share, due to its increase in demand in heavy industrial machinery industry for energy-efficient conveyor systems in manufacturing and automotive industries.
