Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of small starting torque and poor running performance of the shaded pole single-phase asynchronous motor, and overcome the disadvantages of the ordinary pole-changing and speed-changing asynchronous motor's shortcomings of the difficulty in embedded work of the distributed stator winding, and provide a stator with four poles. The pole and stator windings are four concentrated windings, which adopt the phase-shifting starting method, and can change the pole and speed of the stator suitable for micro-motors

Abstract

The invention is about a quadrupole four-winding capacitor phase-shifting motor stator, and relates to a stator of a motor. The quadrupole four-winding capacitor phase-shifting motor stator comprises a pole-changing stator part and a pole-changing magnet yoke part. Auxiliary windings and working windings of the motor stator adopt centralized winging structure and a phase-shifting starting mode, and the motor stator structure is suitable for a micro motor. Compared with a shaded pole type single-phase asynchronous motor, the motor stator has the advantages of high motor efficiency, the large starting torque and good operation performance. The pole-changing stator part is used with the pole-changing magnet yoke part, and then a pole-changing speed change can be achieved. A stator part II is used in a motor which does not need pole changing and speed changing. Compared with the pole-changing stator part, the auxiliary and working windings of the stator part II are distributed on a radial outside edge of the stator part II, so the diameter dimension of the stator part II is smaller.

Description

technical field [0001] The present invention is a stator of a four-pole four-winding capacitive phase-shift motor, which relates to a stator of a motor, in particular to a stator whose magnetic poles are four-pole, the stator winding is four concentrated windings, and adopts a phase-shift starting mode, and A stator suitable for micro motors capable of variable poles and variable speeds. Background technique [0002] The shaft power of the fan pump load is proportional to the cube of the speed, and the size of the fan pump load can be adjusted by adjusting the motor speed. There are usually two technical solutions for adjusting the speed of the motor: the frequency conversion speed regulation method and the pole-changing speed-changing method. The frequency conversion speed regulation method needs to be equipped with a frequency converter, and its overall cost is greater than that of the pole-changing speed-changing method. Motor stator windings are divided into two catego...
