Abstract

The invention relates to the field of motors, in particular to a single-phase transverse flux full-control switched reluctance motor, and aims to solve the problem that the traditional single-phase switched reluctance motor is high in output torque fluctuation, low in output torque density and incapable of outputting continuous torque. The single-phase transverse flux full-control switched reluctance motor in a cylinder structure comprises a stator, a rotor and a motor output shaft. An air gap is formed between the stator and the rotor. The rotor is fixed outside the motor output shaft. The stator comprises a stator core, a front upward stator winding, a front downward stator winding, a rear downward stator winding, and a rear upward stator winding. The rotor comprises a permanent magnet, a front rotor core and a rear rotor core. The permanent magnet is a circular permanent magnet. The single-phase transverse flux full-control switched reluctance motor has the advantages that the output torque fluctuation is reduced by 20%, the output torque density is increased by 10% compared to that of the traditional motor, the motor can output continuous torque, measuring process of the switched reluctance motor is simpler, and manufacturing cost of the switched reluctance motor is reduced. The single-phase transverse flux full-control switched reluctance motor is applicable to the field of motors.

Description

technical field [0001] The invention relates to a reluctance motor and belongs to the field of motors. Background technique [0002] The stator and rotor of the traditional two-phase switched reluctance motor are salient pole structures, and the number of teeth of the stator and rotor cores is equal, and the stator and rotor cores are single-section cores. By sequentially energizing the stator excitation winding, the excitation current of the winding is a unidirectional current, and the stator pole interacts with the rotor pole to generate torque. There are neither windings nor permanent magnets on the rotor, so the structure of the motor is simple and the operation is reliable. However, due to the two-tooth structure of the stator core of the single-phase switched reluctance motor, the change rate of the inductance of the motor is once within an electrical angle period of 180 degrees, which makes the output torque of the single-phase switched reluctance motor fluctuate gre...
