GROB Electromobility
GROB remains a strong partner in the automotive industry
As one of the few worldwide machine manufacturers, GROB is now, following years of involved development work, wholly committed to electromobility and is expanding its product range by this pivotal and future-facing sector. GROB is fully supporting its customers with the development and realization of new system concepts for the production of hybrid and electric drives. In doing so, the company is consolidating its global role as a capable system supplier and dependable partner to the automotive industry.
Comprehensive GROB expertise – from the initial idea through to series production
Four years ago, in response to the increasingly progressive pace of technological change with vehicle powertrains, GROB established a Research and Development Team that focuses solely on electromobility. Close consultation with renowned representatives from the automotive industry soon revealed a high demand for mass production equipment in this sector, the focus being on two core areas, the electric motor and the battery.
To accelerate the set-up and development phase, GROB consolidated its knowledge of winding and inserting technology and, in early 2017, acquired a renowned mechanical engineering partner for the production of electric motors – DMG mecchanica. The company was renamed in 2018 to GROB Italy S.r.l. In addition, a dedicated, ultra-modern development and application center for electromobility was constructed at the Mindelheim site. In close collaboration with the automotive industry, engineering processes and methods for the series production of high-efficiency electric motors and extremely compact battery modules with a high power density are being developed and trialed here on over 2,500 m² of space. "GROB is currently working on several projects for electric drives in the international automotive industry," says German Wankmiller, Chairman of the Board & CEO. He goes on to explain: "Thanks to a team of specialists and development engineers, GROB can realize each and every one of these projects. As a general contractor, we are already able to handle large orders and offer machines and systems for electric motors, battery modules and fuel cells." For stator production in particular, there are various manufacturing methods for inserting copper wires into the stator slots. GROB offers the wave winding technology, the hairpin method and the fan coil technology. In addition, GROB Italy S.r.l. covers the inserting technology and needle winding. The new GROB machine portfolio, then, comprises the entire manufacturing process for an electric motor, including the various methods of wire winding and forming, assembly and contacting. GROB supports its customers, from the initial idea to the system concept for prototypes through to large-scale series production.

The latest product and technology solutions regarding HEV&EV of GROB
The 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 S.r.l. also covers the winding/inserting technology as well as the needle winding.
For battery cells currently round, prism and pouch cells are used. These are assembled to form a module. Planning parameters such as degree of automation, cycle time and output quantity are individually adapted to customer requirements. New processes, materials and technologies are researched and tested with regard to their suitability for use in the automotive industry. A very varied mechanical engineering is required for module assembly (cell assembly, module assembly, packing assembly). This means that GROB can market and operate all the production processes required in the automotive industry.
