Abstract

The invention relates to a low-torque ripple reluctance motor with a self air-cooled rotor, and belongs to a reluctance motor. The motor comprises a rotor and a stator, a salient-pole tooth of the rotor is an oblique tooth in a structural shape of an axial-flow fan blade and is decided by an air intake angle, an air outlet angle and rotor length, and the structure of a salient-pole tooth of the stator keeps electrical property of the motor consistent with the prior double-salient-pole motor with an oblique rotor tooth. When the rotor of the motor rotates, the salient-pole tooth of the rotor generates an air suction force to introduce the air inside the motor to be exhausted by an air outlet, so as to take away heat of the rotor of the motor and achieve the aim of self air cooling. The low-torque ripple reluctance motor is suitable for the reluctance motors with various structures, which comprise a double-salient-pole motor, a switched reluctance motor, an inductor motor, and the like.The low-torque ripple reluctance motor can automatically dissipate heat of the rotor of the reluctance motor, reduce volume and weight of the motor, and optimize the size of the motor.

Description

technical field

[0001] The invention relates to a self-air cooling rotor low-torque pulsating reluctance motor, including a switched reluctance motor, a doubly salient pole motor, an induction motor, etc., and belongs to the technical field of motors. Background technique

[0002] The reluctance motor realizes the conversion of electromechanical energy through the change of reluctance. Such motors mainly include switched reluctance motors, doubly salient motors, and induction motors. Taking the double salient pole motor as an example, the rotor is punched and laminated with silicon steel sheets, and there is a salient pole structure on the rotor, no winding, no brush, so this type of motor has the outstanding advantages of simple structure and reliable operation, especially suitable for Run at high speed. In addition, electrically excited doubly salient motors also have the advantage of relatively low excitation power, so doubly salient motors have broad application prospe...
