Specific use of lightweight materials (fiber-reinforced composites, soft magnetic compounds) and a highly compact, automatically produced copper wire winding led to a weight reduction by about 20% compared to a reference motor of the same class. In particular, rotor weight was decreased, as a result of which the moment of inertia was reduced by about 15%.Weight reduction in particular resulted from the development of a process to produce CFRP-steel hybrid shafts and a two-component injection molding process for the scalable manufacture of lightweight rotor disks from soft magnetic compounds (SMC). A lightweight housing made of CFRP with an integrated modular cooling system ensures optimum cooling of the stator winding. The latter is produced by an automatic needle winding process for a high degree of filling and a small external diameter of the stator.
