Description

technical field [0001] The invention relates to the field of motors, in particular to a permanent magnet coupling speed-regulating motor. Background technique [0002] Speed ​​regulation operation is recognized as one of the best ways to realize motor energy saving. There are three main methods for motor speed regulation operation: [0003] 1. Electromagnetic speed regulation [0004] Electromagnetic speed regulation is composed of cage motor, electromagnetic slip clutch and DC excitation power supply (controller). The electromagnetic slip clutch is composed of armature, magnetic pole and excitation winding. The armature is coaxially connected with the cage motor rotor and driven by the cage motor. The magnetic pole is connected to the load through the coupling, and the excitation winding is connected to DC. When the armature rotates with the cage motor, due to the relative motion between the armature and the magnetic poles, the armature induces eddy current, which interac...
