Problems solved by technology

[0002] For the distributed winding, when winding the stator of the existing motor, after the coil winding of one phase winding is completed, when starting to wind the other phase winding, the winding needs to reposition the starting slot of this winding, which will cause the winding At the same time, when two sets of coils need to be placed in each slot of the existing winding of the high-voltage motor, since the two coils belong to different phases, insulating materials need to be placed between the two coils for each slot coil, and the production process is more cumbersome.

Embodiment Construction

[0020] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0021] The purpose of the present invention is to aim at the permanent magnet motor whose unit motor is 9 slots and 4 poles, and the applicable slot pole ratio is K*(9 slots / 4 poles), wherein K is an integer coefficient. Further description will be made by taking a slot-to-pole ratio of 2*(9 slots / 4 poles) as a preferred embodiment.

[0022] A kind of permanent magnet motor stator winding method with 9 slots and 4 poles in the unit motor, such as figure 1 with figure 2 As shown, the stator slots marked with the same serial number in the figure represent the same stator slot, the tail end X of the first winding is correspondingly connected to the head of the second winding V, and t...

Abstract

The invention relates to the technical field of motor wire winding, and particularly discloses a permanent magnet motor stator wire winding method of which each unit motor is provided with 9 grooves and 4 electrodes. The method comprises the steps of winding for several circles along the first stator groove and the third stator groove to form a first coil; winding out of the first coil and windingfor several circles along the fifth stator groove and the third stator groove to form a second coil; winding out of the second coil and winding for several circles along the fifth stator groove and the seventh stator groove to form a third coil to complete first-phase wire winding of each unit motor; with the last stator groove of first-phase wire winding being the first stator groove of second-phase wire winding, repeating the step of first-phase wire winding to complete wire winding of the first unit motor; repeating the steps of the first unit motor to complete wire winding of K unit motors. Homodromous wire winding is achieved, multiple times of locating of the stators during wire winding is avoided, the production efficiency is improved, the running performance of the motors can be improved, the magnetic field distortion caused by tooth harmonic can be reduced, and the wire winding quantity is reduced.
