Big torque motor of magnetism gear low -speed

The utility model provides a big torque motor of magnetism gear low -speed includes: inner rotor, magnet adjustment ring and stator that the from interior to exterior coaxial was arranged in proper order wherein, are provided with the permanent magnet in the inner rotor, be provided with production rotating field's armature winding and the electromagnet that produces the stationary magnetic field in the stator. Owing to adopt the electromagnet to produce the stationary magnetic field in the stator, owing to adopt the electromagnet to replace the permanent magnet in the stator, can reduce the quantity of permanent magnet to reduce outer gas length, improved armature group magnetic field and inner rotor permanent magnetism magnetic field coupling degree then.
