Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of ordinary claw pole permanent magnet synchronous motors without fixed rotation direction and small starting torque, and to overcome the shortcomings of ordinary disk-type brushed DC motors with brushes and commutators, and to overcome the disadvantages of ordinary disk-type permanent magnet synchronous motors. Synchronous motors cannot be started directly, and need to be equipped with a motor controller. The disadvantage of high cost is to provide a claw pole that can be started by phase shifting, simple in manufacturing process, low in cost, small in number of winding coils, large in electromagnetic torque, and good in heat dissipation conditions of the motor.

Abstract

The present invention discloses a claw pole disc asynchronous electric motor and relates to an electric motor. The claw pole disc asynchronous electric motor comprises a rotor component and a stator component. A claw pole magnetic pole and an axial motor air gap are adopted by the motor. Capacitor phase shifting start is adopted, a fixed rotation direction is set, and a working winding coil and astarting winding coil are shared. The motor has the advantages of simple manufacturing process, low cost and a small number of winding coils of a claw pole motor with a large number of magnetic polesand the advantages of a large electromagnetic torque and a good motor heat dissipation condition of a disk motor, and the motor can be widely applied to small low-rotation-speed electric motors of anelectric valve actuator, a medical instrument and precision transmission.

Description

technical field [0001] The invention relates to a claw-pole disc-type asynchronous motor, which relates to a motor, in particular to a claw-pole disc-type asynchronous motor adopting claw pole magnetic poles, an axial motor air gap, and phase-shifting start. Background technique [0002] Claw pole motors have the advantages of simple manufacturing process, low cost, and fewer winding coils in low-speed motors with a large number of magnetic poles. The most widely used structure type of claw pole motors is the claw pole permanent magnet synchronous motor, which is mainly used in micro motors such as electric fan oscillating motors and microwave oven turntable motors. Claw pole permanent magnet synchronous motor has no fixed rotation direction and small starting torque, which limits its application range. [0003] The disc motor is an axial motor with an air gap, the diameter of the motor rotor is large, the electromagnetic torque is large, the heat dissipation condition of t...
