Problems solved by technology
The magnetic poles of the rotor are usually protruding magnetic poles. During the operation of the two-phase switched reluctance motor, when the protruding rotor magnetic poles are getting closer and closer to the stator magnetic poles, due to the obvious change in the distance between the two, resulting in It will be subjected to a lot of air resistance, and it will also cause harsh screaming noise, vibration, etc., especially pulsation, low-frequency vibration and noise caused by low-speed operation, resulting in reduced efficiency and performance of the two-phase switched reluctance motor
[0003] In addition, existing two-phase switched reluctance motors do not have self-starting capability

The invention discloses a two-phase self-starting switch reluctance motor comprising a stator component and a rotor component coaxially arranged, wherein the stator component comprises a plurality ofstator iron cores which are W-shaped or extended W-shaped, each stator iron core comprises a stator iron core root and a plurality of teeth extending radially from the stator iron core root towards the rotor component, the total number N of the plurality of teeth is an odd number, and N is not less than 3. According to the motor provided by the invention, the weight is significantly reduced, and the noise and vibration are also significantly reduced.
Description
technical field [0001] The invention belongs to the field of motors, in particular, the invention relates to a lightweight two-phase self-starting switched reluctance motor. Background technique [0002] The traditional two-phase switched reluctance motor has a simple structure and is easy to control. Both the rotor and the stator are provided with multiple magnetic poles, and the interaction between the magnetic poles drives the rotation of the shaft, which in turn drives the rotor mounted on the shaft to rotate. The magnetic poles of the rotor are usually protruding magnetic poles. During the operation of the two-phase switched reluctance motor, when the protruding rotor magnetic poles are getting closer and closer to the stator magnetic poles, due to the obvious change in the distance between the two, resulting in It will be subject to great air resistance, and it will also cause harsh screaming noise, vibration, etc., especially pulsation, low-frequency vibration and noi...
