Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, a permanent magnet two-phase brushless motor with divided stators includes a stator 1, a main winding 11, an auxiliary winding 12, a permanent magnet rotor 2 and a starting device. The stator 1 is composed of two divided stators 3, and the divided stators The slot number 31 of 3 is a multiple of 3, and the sum of the slot numbers of the stator is a multiple of 6; for example figure 1 As shown, the number of slots of the sub-stator 3 is 6, and the total number of slots of the stator is 12; the stator teeth 32 and the permanent magnet rotor 2 have no eccentric air gap 33 .

[0027] The main winding and the auxiliary winding adopt the distributed winding method on the stator. The ratio of the number of slots between the main winding and the auxiliary winding is 2:1. The main winding is reversely wound, the secondary winding is reversely...

Abstract

The invention relates to a permanent magnet two-phase brushless sub-stator motor, which comprises a stator, a main winding, an auxiliary winding, a permanent magnet rotor and a starting device, and is characterized in that: the stator consists of at least two sub-stators; the slot number of the sub-stators is the multiple of 3; the total slot number of the stator is the multiple of 6; and an eccentric gap is not formed between a stator tooth and the permanent magnet rotor. The motor has the advantages that: 1, the defect of vibration and noise generated by magnetic flux distortion due to the eccentric gap in the prior art is overcome; and 2, the eccentric gap is not formed, so the motor can rotate clockwise and anticlockwise, and the application field of a product is expanded. In addition, due to a sub-stator structure, a winding machine special for the sub-stators has a high speed, a few copper or aluminum wires are used, and working hour and materials are saved.

Description

technical field [0001] The invention relates to a motor, especially a stator and a starting device of a permanent magnet two-phase brushless motor without an eccentric air gap. Background technique [0002] In the current prior art, a permanent magnet two-phase brushless motor includes a permanent magnet rotor, a stator core, and a stator winding. There is an eccentric air gap between the permanent magnet rotor and the stator teeth; the stator winding adopts a centralized winding arrangement. The existing problem is: due to the one-to-one correspondence between the magnetic poles and the stator teeth and the existence of the eccentric air gap of the stator teeth, the motor vibrates and generates noise. Contents of the invention [0003] The purpose of the present invention is to provide a permanent magnet two-phase brushless motor with divided stators, which can effectively suppress the vibration of the motor and reduce the noise. [0004] The present invention is achieve...
