Embodiment 1

[0019] For a three-phase stator winding of a motor, the order of the teeth wound by the winding method of the present invention is respectively:

[0020] For the U-phase winding, there are two ends of A and X: first wind the first tooth in a clockwise CW direction, then wind the second tooth in a counterclockwise CCW direction, and then cross the 4 teeth arranged in sequence and keep CCW in a counterclockwise direction around the 7th tooth Then wind the 8th tooth in a clockwise CW direction, similarly, wind around the 13th and 14th teeth, cross 4 teeth, then wind the 19th and 20th teeth, wind around the 25th and 26th teeth, cross 4 teeth, and then wind the 31st and 26th teeth 32 teeth;

[0021] V-phase winding, with two ends of B and Y: first wind CW around the 3rd tooth in a clockwise direction, then wind around the 4th tooth in a counterclockwise direction CCW, then cross the 4 teeth arranged in sequence and keep CCW around the 9th tooth in a counterclockwise direction Then...

Embodiment 2

[0024] For a three-phase stator winding of a motor, the order of the teeth wound by the winding method of the present invention is respectively:

[0025] U-phase winding: firstly wind CCW around the first tooth, then wind CW clockwise around the second tooth, then straddle the 4 teeth arranged in sequence, keep clockwise CW around the seventh tooth, and then wind CCW counterclockwise The 8th tooth, in the same way, go around the 13th and 14th teeth, cross 4 teeth, then go around the 19th and 20th teeth, go around the 25th and 26th teeth, cross 4 teeth and then go around the 31st and 32nd teeth;

[0026] V-phase winding: first wind around the 3rd tooth counterclockwise CCW, then wind the 4th tooth clockwise CW, then cross the 4 teeth arranged in a clockwise direction and keep clockwise CW around the 9th tooth, then wind CCW counterclockwise The 10th tooth, in the same way, go around the 15th and 16th teeth, cross 4 teeth, then go around the 21st and 22nd teeth, go around the 27...

Abstract

The invention relates to a stator which comprises a stator core, an end insulator and stator windings, wherein a plurality of teeth protrude the side wall of the stator core outwards, a wire inserting groove is formed between two adjacent teeth, and the stator windings are inserted in the wire inserting groove and are wound on the teeth. The stator characterized in that the in-phase stator windings adopt the wire winging method that the in-phase stator windings are continually wound on the two adjacent teeth, then stride four teeth and then wound. The wire winding method is convenient, centralized and practical; the novel fractional slot winding can be obtained, the cogging torque of the motor is greatly reduced, and the motor runs smoothly; and the vibration of the motor is reduced, therefore, the noise and the failure rate of the motor are reduced, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to a motor stator. Background technique [0002] At present, the existing stator structure includes stator core, end insulation, and stator winding. There are several teeth protruding from the side wall of the stator core, and a wire slot is formed between two adjacent teeth. The stator winding is embedded in the wire The slots are wound on the teeth, and the winding methods of the stator windings are various, among which the most conventional one is that the winding directions on each tooth are the same, both clockwise CW or counterclockwise CCW; for three-phase motor windings U, The windings of each phase of V and W, wind around 1 tooth, span 2 teeth and then wind around the 4th tooth, and so on; image 3 As shown, the order of U-phase teeth winding in the same direction is the 1st, 4th, 7th, and 10th teeth, the order of V-phase teeth winding in the same direction is the 2nd, 5th, 8th, and 11th teeth, and the sequence of W-phase...
