Description

technical field

[0001] The invention belongs to the field of permanent magnet motors, in particular to a squirrel-cage conductor rotor brushless power feedback type permanent magnet governor. Background technique

[0002] With the promotion and application of high-performance permanent magnet materials, the permanent magnet speed control technology, which has developed rapidly, is a new type of speed control and energy-saving technology for motor drive systems applied between the prime mover and the load. The speed-regulating permanent magnet coupler has a good energy-saving effect, reduces operating costs, and can also realize the soft start and soft stop functions of the motor. It can operate in harsh environments such as flammable, explosive, humid, and high dust content, and it is a mechanical structure that can adapt to situations such as unstable power grid quality and impact loads caused by current changes. Mainly used in the chemical industry, petrochemical industry...
