Euro Group, magnetic steel laminations worldwide

Stampa

Euro Group is the industrial holding company of an italian metalworking group with 51 years of history. It has grown to become a world top player in the production of magnetic steel laminations for stators and rotors of electric motors and generators.

Euro Groups market presence is worldwide, with 7 production units in Italy and another 5 in Mexico, United States, Tunisia, Russia and China.

The market for electric motors is increasingly demanding in terms of product complexity, shorter project development to market time, price competitiveness and high service level.

Euro Group meets these demands as a global partner who can offer solutions from dedicated production facilities to provide the best fit for all our customer requirements. To achieve these targets it has become master craftsman of its historical technologies (tool design and manufacture, blanking, die-casting, core assembly and slinky).

The company also cooperates as partners in the development of new families of magnetic steels.

Euro Group identifies and develops cutting-edge new technologies (for example laser welding, self-bonding steels, in-die gluing) and approaches new business opportunities with a structured Project Management, who have access to fast prototyping and numerical tools to simulate processes and designs to mitigate risks in serial production.

Air becomes electric

Specialized since the foundation, in 1955, in the production of laminations for motors and transformers, Trancerie Emiliane, owned by Felisa family, are unavoidably interested in the e-mobility theme.

At the beginning, it was the sound, and precisely the unmistakable one by Beatles. On tour in Italy in the early Sixties, the four from Liverpool clearly needed all possible stage equipment, starting with amplifiers. They were supplied by Davoli’s made in Italy, whose resonance boxes were echoed by the transformers by a small Parma company. We are speaking of Trancerie Emiliane that few years before had stemmed from the entrepreneurship of Pietro Felisa, founder driven by ingeniousness and the will of leaving war miseries behind. Since then, Felisa workshop has developed up to gaining the sizes and the renown as big international manufacturer of laminations for transformers and electric motors, entering the world of induced activities of leader global brands in automotive and not only. Today it relies on a subsidiary in Slovak territory and 350-400 workers in all, with a turnover of 150 millions. The time seems propitious for further great strides, due to the clamour aroused by the race to e-mobility.

Felisa family. From left: Paolo, Nadia, Pietro (founder) and Franco

The managing director Franco Felisa strongly believes that the electrification of light transports, or at least their strong hybridization, represents the (sustainable) future of mobility and perhaps of even human kind, even if he is aware that the road to be travelled is still long and will reserve new surprises.
«E-cars and hybrid», he told Electric Motor Engineering, «are the vehicles of the future but I do not think that their definitive success, that is to say the complete replacement of thermal engines with electric motors, can be implemented in the short term.
Let us just consider the infrastructural deficiencies from which we suffer, for instance, in terms of energy production and distribution capacity.

Trancerie Emiliane has developed up to gaining the sizes and the renown as big international manufacturer of laminations for transformers and electric motors, entering the world of induced activities of leader global brands in automotive and not only

The game and the candle

In spite of that, the investments by big brands and by some representatives of their induced activities do not seem to leave any doubt: they are constantly growing.
The numbers at stake are attractive even if, currently, the planned output is in most cases equal to less than one tenth of means of transport produced in the world in one year.
While vendors generally compete on the distance covered and the mileage of their cars, their supply chain, to which also Parma brand refers, copes with fully different matters, like the development of the production of new components that imply the implementation of equipment to be used in brand-new forefront manufacturing lines.
«Another fundamental step for the success of the electric mobility», commented Franco Felisa, «is represented by the development of batteries, and the issue is not exclusively of commercial or technological character.
The automotive industry is working hard to establish long-term agreements with the owners of lithium mines to be sure it will be supplied with the precious mineral.

A shock of realism

In the opinion of Franco Felisa, batteries must be recharged in the lapse of few minutes and the recharge must be sufficient for hundreds of kilometres to allow zero-impact four-wheels to keep their promises and to meet market requirements.

Nowadays, unfortunately this technology is not available, yet, and, in fact, it needs too much time for a complete recharge, with which it is not possible to travel long distances, yet, and anyway at low average speed.
To succeed in the aim of giving more autonomy and higher average speed to vehicles, manufacturers must strive to produce less energy-eating electric motors.
One of the feasible ways is certainly the reduction of sheet metal thicknesses.
Instead of the common 0.5 mm thickness used for standard electric motors, already today automotive uses thicknesses from 0.35mm to 0.27mm, but some automotive companies report and produce prototypes with sheet metal thickness of 0.19 mm.
This requirement urges the entire chain to an epochal change in the implementation, for instance, of the necessary steels, as well as of apt equipment and machines for blanking the laminations for the production of electric motors.

Today Trancerie Emiliane relies on a subsidiary in Slovak territory and 350-400 workers in all, with a turnover of 150 millions

In my opinion, this is the approximate situation we are likely to face for the whole current year.
From 2020 to 2021, the numbers of electric vehicles introduced by companies into their ranges will be much broader.
Certainly, we cannot get off the running train of the e-mobility and Trancerie Emiliane are ready for racing and for satisfying its customers’ demands and needs.

Zero tolerance

In comparison with past years, before the 2008-crisis, certainly the whole market scenario has radically changed, for instance with delivery terms dropped from some months in the past to the present few weeks, as well as quality, irredeemably shifted to zero PPM. Despite criticalities, Felisa irremissibly considers automotive as the core of his company’s next initiatives and he is certain the future coincides with the diffusion of the e-car.

4.0 blanking

«We have clear ideas about what we would like to do», he anticipated, «but in a scenario of such a difficult interpretation caution is mandatory.

We imagine a robotic “next” factory, with electric trains that will handle goods in absolute autonomy, and fully automated warehouses, too, without anyway ever forgetting the human factor that is, and must remain, the focus of each of our thoughts or actions. On the other hand, employees’ competences and their way of working are expected to live an epochal change. Besides machines, workers are and will be called to increasingly use forefront consoles of collection and transfer of data concerning single job orders and all that can be used to fulfil them.

AIDA MSP
AIDA presses in Trancerie Emiliane plant

The AIDA MSP allows producing high precision and high-efficiency motors such as EV motors, HEV motors and energy-efficient home appliances motors. AIDA MSP presses are characterized by a remarkable dynamic precision due to both the compact design and the multiple suspension points architecture in line, to the native AIM function (Adjust In Motion) and to the balance reached between the high rigidity and the large surface of bed area. AIDA MSP presses guarantee unsurpassed accuracy and the longest die life thanks to the lowest deflection characteristics. Moreover, all areas that transmit the press the forming loads, such as the connecting rod bearings and the crankshaft bearings, are made from special metals selected to avoid heat deformations. Ideal for production of parts featuring thicknesses under 0.2 mm Multiple suspension points Oil temperature control unit Caliper type clutch and brake Highly rigid frame Highly rigid guidepost Adjust In Motion function (AIM)

Trancerie Emiliane has recently bought new AIDA presses that will be interconnected with the company, actively participating in the industry 4.0 project

We imagine the next job as absolutely less heavy from the physical point of view but much more committing in intellectual terms.
To compete globally, we must create further flexibility and this is accomplished through studies and investments in people and machines.
Trancerie Emiliane’s programme includes the implementation of a central unit or control tower that tracks in integrated way the information about activities in course and productions, the state of the art of each machining, which can be monitored step by step from remote.
Concerning this, Trancerie Emiliane has recently bought new AIDA presses that will be interconnected with the company, actively participating in the industry 4.0 project.

Elemaster, designing and developing electronic technologies

Lomagna plants covers 23,000 square metres and can host over 500 people

Managing the entire product lifecycle. These are the skills of Elemaster, which ranges from the design to the industrialization and certification of electronic instruments, from rapid prototyping to mass production, from the manufacturing of custom components, like the printed circuit board, to the supply of “turnkey” products, up to logistics and after sales service.

It operates in the sector of Original Design Manufacturing and of Electronic Manufacturing Services and nowadays its activity includes the design and manufacturing on a world scale of electronic equipment with high technological content. It is Elemaster Group, which in this issue of Electric Motor Engineering we have involved for a focus on industrial sector realities.

Today Elemaster is organized as an Electronic Technology Partner, as it can manage the entire product lifecycle: from the design to the industrialization and certification of electronic instruments, from the rapid prototyping to the mass production, from the manufactoring of custom components like printed circuit boards and custom cables to the electromechanical integration and the supply of “turnkey” products, up to logistics and after sales service.

Elemaster in particular works with a rising number of “fabless” companies, which outsource the manufacturing activity, focusing their strategic efforts on the marketing and sale of products. This market evolution has determined a new value proposal, meant as the offer of integrated services with high added-value generated by the research and development activity that concerns both products and manufacturing processes, increasingly oriented to the lean manufacturing.

Elemaster: from 1978 to 2018 a long entrepreneurial and family course
From left: Giovanni Cogliati (Sales & Marketing Manager); Gabriele Cogliati (CEO and President); Rosella Crippa (Vice President); Valentina Cogliati (Managing Director)

The history of Elemaster started in October 1978, when in a basement in Merate (Lecco province) Gabriele and Rosella Cogliati, two people in their early twenties and recently married, lay the bases of a long entrepreneurial and family course. “The origin of our whole history, from 1978 until now, when we celebrate the fortieth anniversary since the foundation, stemmed from the courageous initial decision of giving up a stable and well paid job to undertake our own autonomous activity, aware of sacrifices and renunciations, putting at disposal our scarce economic resources”, starts explaining Gabriele Cogliati, today CEO and President of a Group worth 220 million Euros of turnover, over one thousand of workers employed in Italy, Europe and worldwide, with a strong bent for internationalization and a constant boost to technological innovation. Cogliati intended to offer a technical service of engineering and industrialization of the electronic product component to its customers and the latter immediately show a growing confidence: orders increase and, in addition to design, the demand for the prototype implementation starts. In Italy, it is the time of the development of electronic and information technologies, there is a growing demand for innovation and Elemaster finds its way with its own business model, becoming partner and reference reality for its customers. From the design and prototyping to the production of pre-series and then of turnkey finished products the distance is short. The space and the small group of collaborators of the origins are no longer sufficient, it becomes necessary to build a factory at Montevecchia, 2,000 square metres hosting about 50 employees: we are in 1988. Initially dedicated to the industrial automation sector, since 1990 onwards Elemaster has approached the energy and afterwards the medical sector, then gaining specialized competences in the transport sector, especially railway and avionics. At Montevecchia the development goes on with the vertical offer integration, through the establishment of a factory intended for the production of printed circuit boards (Eleprint) and, afterwards, through the widening of the manufacturing capacity with a new further local unit, taking up 3,000 square metres and hosting around 150 workers. In 1999, they establish a production site in Basilicata and start taking part in research projects, also due to noteworthy collaborations with the university world. In 2000, all the activities of research, development and hardware and software design are unified in a dedicated company: Eletech. In 2007, a new outstanding enlargement: Elemaster accomplishes the building of the plant at Lomagna that, on 23,000 square metres, can host over 500 collaborators, quadrupling the manufacturing capacity. In the last ten years, the Group has pursued a globalization process that has resulted in the presence, with dedicated design and production units, in Germany, United States, China, India and Africa. In 2016, they launched the “Vision 2020”programme, the industrial plan providing for the strategic development lines of the successive years that the company is currently implementing with great determination and has led to the setup of a commercial branch in France and to the recent takeover of a competitor with premises in Belgium and Romania.

The fortieth anniversary occurs in a time of economic and social uncertainties but Elemaster Group can look at the future with renewed effectiveness, aware it can rely on highly fidelized customers, suppliers and collaborators. The competition is global, the only solution is “Knowing and being able to do” and knowledge, competence, discipline and daily commitment are required in the current context. Elemaster is committed to pursue the outlined course, oriented to the full customer satisfaction, in a context of improvement and constant innovation of processes, services and products.’’ Gabriele Cogliati, Ceo and President of the Group

Elemaster’s supervision of the complete productive cycle, besides allowing a direct control of all process phases, permits customers to rely on a single partner for the entire value creation chain: each of the 6,000 different products (electronic board, electromechanical subassembly or finished product) that the Group manufactures every year is the result of a tailor-made technological solution. 

In the course of its history, Elemaster Group has widened the number of segments and market niches where to operate, today attaining a diversified business portfolio of over two hundred customers subdivided in ten industrial segments. Currently the range of action, on a world scale in high-tech sectors, goes from railway to avionics, medical, automotive, industrial automation and energy, with an all-round activity that allows a positive contamination.

The all-round activity of Elemaster allows a positive contamination, thanks to which the best practices of each sector are extended to other sectors’ productions. Wherever there is an innovative high-tech niche, Elemaster can propose its services in compliance with the highest qualitative standards.

Electric mobility

Among high-tech solutions and services in mobility and automotive sector, in particular, the supply encompasses electronic and electromechanical components, besides completely assembled and tested equipment. Among the main applications, it is worth mentioning control systems for hybrid & electric vehicles, earth-moving machines and heavy vehicles; motor & automatic transmission controls; telemetry and localization systems.
We asked some questions to Claudio Accorsi, Corporate Business Development Manager of Elemaster Group, about the design and production activity for the electric mobility.

What are the growth prospects in the electric mobility sector and at what products does
Elemaster work?
“Elemaster has designed and produced the majority of the electric and electronic systems for the electric mobility for over twenty years. We rank among the primary players in Europe and we are steeply rising in the other continents (USA and China), too, we are working at the biggest machine today existing in the world for the electric mobility: the train. Besides, we supply all ground equipment for the traffic and fleet management. The mantra that accompanies us in the mobility world is Drive by Data”.

Claudio Accorsi, Corporate Business Development Manager Elemaster Group

We are extending the offer for the electric mobility to the automotive industry: we are working with big customers both in Italy and in Germany, from electronic controls for the optimal energy management on board of vehicles to the functional control of sensors as support to the assisted drive. The successive step will concern the cars with autonomous drive.

On what know-how does Elemaster ground its offer?
“The expertise is consolidated and developed by constantly evolving projects, from the implementation of the functional safety in components to the management and reduction of consumptions. One of the most challenging projects for us is the wireless train: for the power supply, we will exploit new energy-accumulation systems applied to ultra-light trains that will travel in cities covering also “the last mile”.
Thanks to this know-how we are extending the offer for the electric mobility to the automotive industry: we are working with big customers both in Italy and in Germany, from electronic controls for the optimal energy management on board of vehicles to the functional control of sensors as support to the assisted drive.
The successive step will concern the cars with autonomous drive: in the next 10-15 years, they will become Wheel Robots in the mobility integrated with trains and planes”.

What companies of the Group are involved and what is their contribution in the project?
Eletech is protagonist in researching and exploring the most advanced technologies available on the market and in supporting customers through co-design services.
Elemaster, due to its ISO TS-certified factories, is the ideal partner to turn innovative ideas into mass productions.

The goal is mass production of highly effective electric motors

Car ride on road in sunny weather, motion blur

Against the background of the paradigm shift in the powertrain of the motorcar, a research and development team was set up at GROB three years ago tasked solely with the theme of electromobility. Working in close collaboration with wellknown representatives from the automotive industry, it quickly became clear that there was a great need for mass production installations in the automotive industry, with a particular focus on key components, namely the electric motor and battery components. In order to accelerate the development work, GROB acquired a renowned partner in machine and plant engineering for electric motors, DMG meccanica, benefiting from its expertise in winding and inserting technology. In tandem, a dedicated development and application center for electromobility was created in Hall 2 at the factory in Mindelheim. Spread over more than 2500 mq² (27,000 ft2), work is under way developing and testing processes and methods in machines and installations in collaboration with the automotive industry. The goal is mass production of highly effective electric motors with completely newly developed technologically, as well as of very compact battery modules with high power density.
The challenge facing GROB now is the task of translating these yet unknown processes and methods into precisely timed movements and workflows in completely newly developed CNC machines. The new, highly flexible and servo-controlled machines are used for mass production of the stator and rotor electric motor components. In stator production, in particular, there are various manufacturing techniques for guiding the copper wires into the slots of the stator. The new GROB machine portfolio covers the entire production process for an electric motor, from various winding and shaping processes for the wires to assembly, to contacting.

The new GROB machine portfolio covers the entire production process for an electric motor, from various winding and shaping processes for the wires to assembly, to contacting.

One of the core processes in the production of an electric motor is the process of guiding the copper wires into the stator. GROB covers all known processes here, including wave winding technology, the hairpin process and fan-coil technology. GROB Italy Srl also covers the winding/inserting technology as well as the needle winding. This means that GROB can market and operate all the production processes required in the automotive industry.

Electromobility spurs the whole company on

When GROB created a new third division ten years ago with the launch of universal machines, it managed to build directly upon the image of the G-modules, since GROB, as a turnkey supplier in the systems business, already had an excellent reputation in the market. It is not the same with ‘electromobility’. With its technology, it is calling for a new way of working and, thus, for changes in approach. While the processes used in existing divisions form the basis and serve as models, it is important to remember that e-mobility is still a relatively new concept for the automotive industry. All market operators have to adjust their approach. Projects are currently only being set up and developed in close consultation with the automotive industry. Many coordination meetings within the project teams of both parties are needed. This is in contrast to our core business of ‘system machines’, where our business is very much up and running. Sales have been enhanced with the recruitment of specialists with experience in electromobility. Customer inquiries are coordinated in an internal sales meeting and are allocated depending on the technology. A project team consisting of project management, innovation management and sales will then be formed to work out the best possible alternative for the customer.

Electromobility is on the rise worldwide

Since GROB has a very good reputation as a turnkey supplier in the automotive industry, we are highly valued as a partner on joint further development projects.

‘Not only that’, said German Wankmiller, ‘we already have a command of the complete process and technology and can market it.’ Even though markets are reacting to this at different speeds, GROB sales has adapted to the new technologies right around the world. Within the GROB Group, there is a uniform approach and sales structure which are closely coordinated with the headquarters in Mindelheim. Europe – more especially Germany – and China are pioneers in the field of electromobility. Within the next few years in China the number of electric vehicles will be fixed by law and consequently there is significant investment there. Initial projects are already in progress at GROB. To sum up, it can already be said that GROB is fully geared up for the theme of ‘electromobility’, identifies demand on the basis of market analysis, develops the right products and is already in a position to deliver. We make large development capacities available and have a dedicated team of designers on hand to develop these innovative technologies further.

DMG meccanica will be renamed as GROB Italy

Gruppo DMGmeccanica
Gruppo DMGmeccanica

Just over a year ago, at the end of January, 2017, GROB acquired a one-hundred percent share in DMG meccanica, the leading manufacturer of machines and systems for the production of stators for electric motors and generators.
The Group took this step in order to strengthen its many years of research and development work in the field of electric mobility. By combining technologies from DMG meccanica with processes developed in-house by GROB, the Group can now offer and supply all production processes and procedures for electric drives for the global automobile industry. Last year, the Group received the first major orders for the new generation of electric drives from the German automotive industry and its Chinese joint ventures, thus confirming the successfully implemented strategy of diversification with new products and orders.

Gruppo DMGmeccanica
Gruppo DMGmeccanica

Following the acquisition, DMG meccanica became part of the GROB Group without any changes being made to its corporate structure. To complete its integration and optimize its structure, DMG meccanica has undergone the final step of the acquisition and been renamed GROB Italy Srl. The Management Board remains unchanged and continues to consist of the DMG meccanica company founders Mr. Marco Debillo and Mr. Mauro Marzolla.

Sales and service branch GROB Italia (Turin), headed by Managing Director Mr. Antonio Goia, will be integrated into GROB Italy Srl during the course of 2018.
As such, GROB Italy Srl will comprise two corporate areas in the long term: DMG meccanica will be renamed as GROB Italy.

This structured initiative points the GROB Group the right strategic direction and also puts us in the ideal position to master new challenges in the future and meet the needs of our customers.

 

Risatti Instruments, testing electric motors

In recent years, companie’s investments  in the production of the electric motor for automotive have exponentially grown. This very particular product typology, in its turn, needs very definite and complete testing processes, to make the motor highly performing.

The experience of Risatti Instruments , combined with the new technologies developed by the company, allow customers to reach the prefixed targets. The testing phase starts from the control of losses in the iron of the assembled stator stack (N1), to optimize all manufacturing phases and then to obtain the highest efficiency. This analysis is carried out also on the rotor (O166) where, in addition, it is also possible to assess the die-casting quality, detecting also eventual interruptions and blows of bars, as well as the aluminium quality, which notably decrease efficiency. Concerning instead the stator testing (H5), four standard tests are carried out: ohmic resistance, stiffness, SURGE and rotation sense, with the further addition of: measurement of the insulation resistance, measurement of the ohmic resistance in alternate, at different frequencies, for the control of copper losses and the detection of the presence of partial discharges.

The issue of finished motor testing follows: of both the only motor, loadless or loaded, with the detection of the characteristic curve, and equipped with reduction and differential gear to evaluate the overall efficiency. The scheme proposed here represents the ideal testing process with the machines by Risatti Instruments, produced according to its customers’ single requirements, with the addition of suitable lab instruments (H3) for executing all tests for the design assessment and life tests, as well as complete tests on batteries.

TE Connectivity offers magnet wire connection solutions

Many manufacturers of motors, solenoids, coils and other assemblies continue to use traditional, manual soldering techniques for magnet wire connections in their products. This can be costly, both in terms of the time required to make these manual connections, and in terms of quality, given that such processes are difficult to control and may result in poor connections.

TE Connectivity (TE) offers alternative solutions for terminating magnet wire, whether it is copper, aluminum or a combination of both. The terminals and splices are supported with application tooling ranging from hand insertion tools up to customer specific machines. High speed, fully automated, integrated systems provide uniform terminations reliably at a very low applied cost. No pre-stripping, soldering or welding of magnet wire is required.

MAG-MATE terminals and SIAMEZE terminals utilize insulation displacement connection technology, while AMPLIVAR terminals and splices utilize compression crimp technology.
