A stator winding method of a permanent magnet motor with 9 slots and 4 poles as a unit motor

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.

Description

technical field [0001] The invention relates to the technical field of motor winding, and specifically discloses a stator winding method of a permanent magnet motor with 9 slots and 4 poles as a unit motor. Background technique [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 are in different phases, an insulating material needs to be placed between the two coils for each slot coil, and the production process is more cumbersome. [0003] Therefore, there is a need in the industry for a motor stator winding method that can solve the above-mentioned problems. Contents of the invention [0004] In orde...
