Rotor shaft: electric vehicle (BEV)

In the case of traction motors, Hirschvogel supplies hollow rotor shafts with minimum wall thicknesses. Furthermore, with the innovative “StackFix“ technology for joining the rotor shaft and sheet stack, Hirschvogel offers a process for producing a rotor which can be employed in large series production. The use of this joining technology not only increases engine performance but also offers an efficient way of cooling the rotor.
