Two-phase multipolar switch reluctance motor

Abstract

The invention discloses a two-phase multipolar switch reluctance motor which comprises a shell, a left end cap, a right end cap, a stator, a rotor, rotor spoke iron, a rotary shaft, a motor controller, two position sensors and two oscillators. Stator magnetic poles and rotor magnetic poles are in a double convex pole structure identical in number of poles, magnet exciting coils of two adjacent magnetic poles are sequentially connected in a one-positive one-negative manner, two adjacent stator magnetic poles form equant double magnet dividing loops, the stator electric poles and the rotor electric poles are distributed into two sections along the direction of the rotary shaft at same intervals, magnet exciting coils of two sections of the stator magnetic poles are connected into two phases respectively, two sections of the rotor magnetic poles are mutually staggered with one magnetic pole angle, and the two position sensors are connected with the motor controller which is connected with the two oscillators through an electronic switch. The two-phase multipolar switch reluctance motor has the advantages of self-starting capability, narrow dead torque area, namely, zero torque area, lowered vacancy rate of a control circuit and a motor body structure, improved performance, simple structure and good cooling performance of a self-ventilation and cooling system.

Description

technical field [0001] The invention relates to a reluctance motor, in particular to a two-phase multi-pole switched reluctance motor. Background technique [0002] In a traditional reluctance motor, each phase is arranged at a certain angle in the circumferential direction. Since only one phase is turned on each time, the other phases are idle. [0003] Traditional two-phase reluctance motors do not have the ability to adjust the steering. In terms of self-starting, although there are many design schemes, the technology is complicated, the manufacture is troublesome, and there is a torque dead zone, that is, a zero torque zone. [0004] The invention patent (application number 201010569625.1) published on February 16, 2011 (publication number 101976924A) provides a single-phase multi-pole switched reluctance motor, including a stator and a rotor. The stator includes stator poles and excitation coils, and the rotor It includes a rotor core and a rotor pole, the rotor pole...

AI Technical Summary

Problems solved by technology

The technical solution of this patent can effectively eliminate the residual magnetism of the magnetic poles and the vibration and noise of the rotor, and has the ability to adjust the steering, but it does not have the ability to self-start, and there is also a torque dead zone, that is, a zero torque zone, resulting in poor performance of the motor. High, which affects the range of use of the motor
