Customized GROB turn-key solutions

Years of research into innovative technologies for the reliable series production of E-machines and electric motors, combined with decades of experience in the system business enable GROB to quickly realize top quality turn-key solutions. GROB supports you from the outset with the design of your products, from the planning phase through to the implementation of assembly systems. As a result, you ideally meet your particular requirements for electromobility and guarantee economic production with the highest yield quantities.

Winding technologies of GROB

GROB develops and produces machines and systems for the large-scale manufacture of electric motors. At our sites in Mindelheim and Turin, we are working on the various winding technologies for round and rectangular wires – depending on drive and motor size. The product range spans from stand-alone, semi-automatic machines through to fully automated turn-key projects for our customers from the automotive industry.

Stator production with hairpin technology
GROB offers an extensive product range for hairpin stators in various sizes. An innovative bending concept creates extreme flexibility and diversity without tool change for a batch size of 1.

Stator production with continuous hairpin
The advantages of the continuous hairpin lie in the economic feasibility of high numbers of slots with large inside diameters. This technology makes small wire cross-sections easily manageable and eliminates the need for complex circuitry. GROB offers two processes for producing the wire mat for the continuous hairpin: Sword winding and flat winding.

Stator production with insertion technology
For decades now, GROB Italy has been offering insertion technology with round wire and can thus offer its expertise for realizing your projects with fully automated manufacturing stations.

  • Flyer winding: The coil is created when the flyer carrying the round wire rotates around a stationary template.
  • Template-based winding: The coil is created when the round wire is wrapped around a rotating template.

Stator and rotor production with needle winding
GROB Italy develops systems for needle winding technology with round wire that are capable of producing both stators and rotors. The prototypes for these machines are already available.
