PERMANENT-MAGNET-EXCITED ELECTRIC MOTOR WITH HEATING DEVICE, AND OPERATING METHOD |
摘要 |
The aim of the invention is to provide an electric motor which has a high torque at low rotation speeds and a high power at high rotation speeds. The invention therefore proposes an electric motor with permanent-magnet excitation having a first active part (10), which is fitted with permanent magnets (11), and a second active part (10), which can be moved in relation to the first active part (10) by magnetic force of the permanent magnets (11). The electric motor also has a heating device (12) with which the magnetic field of at least one of the permanent magnets (11) can be weakened by heating the permanent magnets as a function of a speed of the first active part (10) in relation to the second active part (8).
