Abstract

An electrical machine, in particular an electric motor of a motor vehicle, having a stator and having a rotor which has a rotation axis. An electrical machine can be a brushless electric motor (DC motor) or a synchronous machine, but also a generator. The stator or the rotor has an electromagnet structure, and the other has a permanent-magnet structure which comprises a first quantity of permanent magnets and a second quantity of permanent magnets. At at least the operating temperature (T), the magnetic coercive field strength (Hcji) of the first quantity is greater than the magnetic coercive field strength (Hcj2) of the second quantity. Further, two methods for producing hybrid magnets are provided.
