Abstract

The invention discloses a washing machine, a motor for the washing machine and a stator assembly thereof. The stator assembly comprises a stator core, a stator winding, multiple pieces of insulating slot papers and at least one insulating plug-in, wherein the stator core is provided with multiple stator teeth and multiple stator slots, the multiple stator teeth are arranged at intervals along thecircumferential direction of the stator core, and the stator slots are defined between two adjacent stator teeth; the stator winding is wound on the multiple stator teeth; the multiple pieces of insulating slot paper are arranged in the multiple stator slots in a one-to-one correspondence manner, and each piece of the insulating slot paper is located between the stator tooth and the stator winding; and the at least one insulating plug-in is arranged at an opening of the stator slot and used for closing at least part of the opening, the side, which faces towards the stator tooth, of the insulating plug-in is provided with a groove, and a part of the insulating slot paper is arranged between the stator tooth and the insulating plug-in and located in the groove. The stator assembly of the motor for the washing machine in the embodiment of the invention avoids wind noise generated by the rotation of a motor rotor, improves the safety performance, and is simple in structure, convenient to manufacture and good in user experience.

Description

technical field

[0001] The present invention relates to the field of clothes processing equipment, in particular to a washing machine, a washing machine motor and a stator assembly thereof. Background technique

[0002] In the prior art, the insulating structure of the brushless DC motor consists of an upper insulating skeleton, a lower insulating skeleton and a slot paper. The upper insulating skeleton and the lower insulating skeleton are installed at both ends of the stator core through positioning holes, which can only serve as the coil ends. The role of insulation; the slot paper is installed in the stator slot, which plays the role of insulation between the stator slot and the coil, and there is no other insulating structure between the slots of the stator slot. When the motor rotates at a high speed, the high-speed airflow generated by the rotation of the motor rotor will enter The stator slot slot and the gap between the two layers of coils in the same stator slot fo...
