Permanent magnet motor
An electric motor includes a stator and a rotor rotatably installed in the stator. The stator has a housing and a plurality of permanent magnets. The outer diameter of the housing is less than 40 mm and the ratio of the maximum thickness of the magnets in the radial direction of the rotor to the dia...
