Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] Such as figure 1 Shown is a hybrid excitation fault-tolerant motor based on position self-detection, specifically a three-phase 12-slot / 10-pole motor, including stator 1, rotor 2, permanent magnet 3, armature teeth 4, fault-tolerant teeth 5, armature Coil 6, excitation coil 7 and magnetic isolation layer 8. The armature teeth 4 and the fault-tolerant teeth 5 are evenly distributed along the inner ring of the stator 1, the total number of teeth is a multiple of 2m (m is the number of phases of the motor), and the tooth width of the armature teeth 4 and the tooth width of the fault-tolerant teeth 5 are different. equal. The permanent magnet 3 is embedded in the rotor 2. The permanent magnet 3 is composed of two magnetic strips that are radially symmetrical along the rotor at one end close to the rotor axis. The shape is "V", so that the permanent magnet has both...
