ELECTRICAL MACHINE

摘要

The invention relates to an electrical machine (2), in particular an electric motor of a motor vehicle, having a stator (8) and having a rotor (6) which has a rotation axis (4). In this case, an electrical machine (2) is understood to mean, in particular, a brushless electric motor (DC motor) or a synchronous machine, but also a generator. The stator (8) or the rotor (6) has an electromagnet structure (12) and the other has a permanent-magnet structure (34) which comprises a first quantity (36) of permanent magnets (32) and a second quantity (38) of permanent magnets (32). At at least the operating temperature (T), the magnetic coercive field strength (Hcj1) of the first quantity (36) is greater than the magnetic coercive field strength (Hcj2) of the second quantity (38).
