Abstract

The invention provides an efficient energy-saving dual salient pole synchronous reluctance motor, comprising a motor mechanical body and a motor control part; wherein, the motor mechanical body comprises a motor shell, a stator which is arranged on the internal wall of the motor shell and a rotor which is arranged at the center in the motor shell; the rotor is arranged on a motor shaft; the motormechanical body also comprises a motor end cover which is arranged at the two ends of the motor shell; the motor shaft is connected with the motor end cover by a bearing; a shaft sleeve and an oil seal are arranged between the internal end surface of the bearing and the rotor; wherein, the rotor is provided with 8 salient poles; the stator is provided with 12 salient poles and 12 winding coils which are corresponding to the 12 salient poles.

Description

technical field [0001] The present invention relates to a doubly salient pole synchronous reluctance motor, in particular to a doubly salient pole synchronous reluctance motor with a high efficiency and energy saving effect by setting the ratio of the number of salient poles between the stator and the rotor to be 12:8 . Background technique [0002] The motor is a device that converts electrical energy into mechanical energy, and it is based on the principle that magnetic flux always closes along the path with the smallest reluctance (maximum magnetic permeance). When the centerlines of the teeth of the stator and rotor do not coincide, that is, when the reluctance is not the minimum, the magnetic field will generate torque, forming a reluctance torque, and turning the rotor to the position where the reluctance is the smallest to generate rotation. Distributed at various users, motors are divided into DC motors and AC motors according to different power sources. Most of the...

Problems solved by technology

[0005] DC motor, the rotor has copper windings, the starting current is relatively large, usually 4 to 8 times the rated current, and it is equipped with carbon brushes, which are easily damaged and consume a lot of power during the speed regulation process;

[0006] For squirrel cage motors, the rotor has aluminum bars that are easy to break, which increases maintenance costs. It also has a relatively large starting current, usually 4 to 8 times the rated current, and consumes a lot of power during the speed regulation process;
