Switched reluctance motor with stator partitioned two-phase 6/5 structure

Abstract

The invention relates to a switched reluctance motor with a stator partitioned two-phase 6 / 5 structure. The switched reluctance motor comprises a stator, a rotor, a winding and a motor shaft, wherein the rotor center is integrated with the motor shaft. The switched reluctance motor is characterized in that two E-shaped stators with three poles are provided, the two stators are symmetrical distributed on the periphery of the rotor and the arc center of the stators of overlaps with the center of the rotor, and the rotor is of an uneven salient pole structure with five poles. The outer diameters of the rotor poles are different, and the winding is wound on a stator yoke. The structure is simple, the design is reasonable, and installation and implement are easy. The switched reluctance motor is reliable to use, the torque ripple is reduced, and the areas with zero torque are eliminated, so that the switched reluctance motor can start automatically. The output torque of the motor is increased, the loss is reduced, and the output efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of reluctance motors, in particular to a stator block two-phase 6 / 5 structure switched reluctance motor. Background technique [0002] Today, air conditioners are widely used in homes and other office environments. In 2015 alone, 100 million air conditioners were produced in China for use by major enterprises and families. The switched reluctance motor is a double salient pole, single excitation motor with simple structure and good fault tolerance, and can operate under high temperature and high speed conditions. In view of the many advantages of switched reluctance motors, switched reluctance motors have broad application prospects in air-conditioning equipment. The torque ripple of the motor can be effectively reduced by intelligently controlling and optimizing the structural size of the motor. In addition, the efficiency of the motor must be improved. Like other motors, switched reluctance motors also o...

Problems solved by technology

[0003] The traditional two-phase 4 / 2 switched reluctance motor has large torque ripple and noise, and there is a "dead zone" - the area where the torque is zero, so that it cannot start automatically

Moreover, the magnetic flux path of the motor is long, and the stator will reverse the magnetic flux during the commutation of the motor rotation, resulting in a decrease in the output torque of the motor, an increase in iron loss, and a decrease in efficiency, etc.

Traditional segmented rotor switched reluctance motors use distributed windings for their windings, resulting in increased motor winding ends and increased copper loss
