ELECTRICAL MACHINE

摘要

The invention relates to an electrical machine (2), in particular an electric motor, which is operationally reliable even at an operating temperature (T) above a limit temperature (TG), which is greater than 80°C, substantially without a drop in torque or power, having a stator (8) and having a rotor (6). Either the stator (8) or the rotor (6) has an electromagnet structure (12) and the other has a permanent-magnet structure (34), the proportion of heavy rare-earth elements (HREE) in said stator or rotor being less than 5%, and the proportion of light rare-earth elements (LREE) in said stator or rotor being greater than 5%.
