A Claw Stator Yoke Embedded Permanent Magnet Assisted Dual Rotor Axial Double Salient Pole Motor

Abstract

The utility model relates to a claw-shaped stator yoke embedded with permanent magnets to assist double-rotor axial double-salient pole motors, which belongs to the technical field of double-salient pole reluctance motors. The claw-shaped stator yoke is embedded in the permanent magnet-assisted double-rotor axial double-salient pole motor, including a casing, a first rotor, a second rotor and a claw-shaped stator. The first rotor and the second rotor are fixed on the shaft. Rotating coaxially with the rotating shaft, the first rotor is provided with several salient poles of the first rotor, the second rotor is provided with several salient poles of the second rotor, and the claw-shaped stator is provided with several first stators corresponding to the salient poles of the first rotor. The sub salient poles are also provided with several second stator salient poles corresponding to the second rotor salient poles, and the stator yoke of the claw-shaped stator is symmetrically provided with permanent magnets. The claw-shaped stator yoke embedded with permanent magnets assists the dual-rotor axial double-salient pole motor, which can effectively increase the output torque, reduce the armature current and the loss of the stator yoke under the same output torque, and improve the operating efficiency of the motor. Improve its performance indicators.

Description

technical field [0001] The invention relates to the technical field of double-salient pole reluctance motors, in particular to a claw-shaped stator yoke embedded with permanent magnets to assist double-rotor axial double-salient pole motors. Background technique [0002] The reluctance motor has developed rapidly because of its simple drive circuit, high reliability, and high-efficiency operation in a wide speed range. However, the leakage flux between the adjacent teeth of the ordinary switched reluctance motor will produce negative torque on the rotor, and the greater the current, the more the number of poles (the smaller the distance between poles), the more significant the impact of the leakage flux between the poles. The earth affects the output of the motor. Although the electromagnetic principle and structure are quite simple, the magnetic circuit changes periodically and has serious local saturation, and its design and performance analysis are quite different from t...
