Abstract

The invention discloses a switch reluctance motor comprising a motor base, wherein a stator is arranged on the motor base; a stator winding is wound on the stator; a rotor is arranged in the stator; a rotor shaft is fixed in the rotor; the motor base is provided with a front end cover and a rear end cover; the stator, the rotor and the rotor shaft are located in a sealed space defined by the front end cover and the rear end cover; a rotary transformer is arranged between the front end cover and the rotor; the transformer rotor of the rotary transformer is fixedly connected with the rotor shaft; the transformer stator of the rotary transformer is fixedly connected with t he front end cover; the stator winding is a three-phase concentrated winding; the stator and the rotor are in a doubly salient structure; eighteen magnetic poles are uniformly distributed on the stator; twelve magnetic poles are uniformly distributed on the rotor; and magnetic poles on the stator and the rotor are in a trapezoid gear structure. With the advantages of simple structure, reliable work, steady operation, small torque pulsation and low noise, the motor is conveniently applied on automobiles.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a switched reluctance motor. Background technique [0002] The speed control motor is a kind of motor that changes the speed of the motor by changing the number of stages, voltage, current, frequency, etc. of the motor, so that the motor can achieve higher performance. Including frequency conversion speed regulation motor, DC speed regulation motor. Since the DC motor has the characteristics of low speed and high torque, it cannot be replaced by the AC motor, so the DC speed control motor has been widely used in the fields of industrial DC motor speed control, industrial conveyor belt speed control, lighting adjustment, computer power cooling, DC fans, etc. application. [0003] China Patent Authorization Announcement No. CN 202395551U, the utility model patent of the authorized announcement date on August 22, 2012 discloses an electric excitation brushless starter and generator...
