Abstract
A rotor () for an electric motor has a force-transmission region () which is operatively connected to a motor shaft (). A torque-transmission region () which is composed of fibre composite materials is adjacent to the force-transmission region (). A magnetic connection region () and a region () for magnetic field guidance with magnets () are arranged on that side of the torque-transmission region () which is situated opposite the force-transmission region (). The motor shaft can also be formed from fibre composite materials. Since the magnetic connection region () 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.
