Abstract
A permanent magnet brushless motor has a stator, an armature winding, a rotor, and a permanent magnet. The stator is provided with an armature groove. The armature winding is placed in the armature groove. The stator and the rotor are spaced apart by an air gap; the permanent magnet is attached to the surface of the rotor, and is magnetized by a Halbach array structure. The motor is an eight-phase motor, and phases are evenly distributed at a phase belt angle of 45°. The motor and the proposed control algorithm have good fault-tolerant effects, and the average torque after fault tolerance is basically consistent with that in normal operation.
