Abstract

A rotor (10) for an electric motor has a force-transmission region (11) which is operatively connected to a motor shaft (12). A torque-transmission region (13) which is composed of fibre composite materials is adjacent to the force-transmission region (11). A magnetic connection region (14) and a region (15) for magnetic field guidance with magnets (16) are arranged on that side of the torque-transmission region (13) which is situated opposite the force-transmission region (11). The motor shaft can also be formed from fibre composite materials. Since the magnetic connection region (14) has a plastic which is provided with a magnetic or magnetizable filler, a rotor for an electric motor and also a motor shaft which interacts with said rotor which are of lightweight construction are provided, said rotor and motor shaft meeting the required performance criteria.
