Abstract

The invention discloses a washing machine, a motor for a washing machine and a stator assembly thereof. The stator assembly includes a stator core. The stator core has a plurality of stator teeth and a plurality of stator slots. The plurality of stator teeth are spaced along the circumferential direction of the stator core. arrangement, a stator slot is defined between two adjacent stator teeth; a stator winding, the stator winding is wound on a plurality of stator teeth; a plurality of insulating slot papers, the plurality of insulating slot papers are arranged on the plurality of stator slots in one-to-one correspondence, Each insulating slot paper is located between the stator teeth and the stator winding; at least one insulating insert is provided at the slot of the stator slot for closing at least part of the slot, and the side of the insulating insert facing the stator teeth has a concave Groove, a part of the insulating groove paper is located between the stator teeth and the insulating insert and is located in the groove. The stator assembly of a washing machine motor according to an embodiment of the present invention avoids wind noise caused by the rotation of the motor rotor, improves safety performance, has a simple structure, is easy to manufacture, and has a good user experience.

Description

technical field

[0001] The 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 insulation structure of the brushless DC motor is composed of an upper insulating frame, a lower insulating frame and slot paper. The upper insulating frame and the lower insulating frame are installed at both ends of the stator core through positioning holes, and can only serve as coil ends. The role of insulation; the slot paper is installed in the stator slot to play the role of insulation between the stator slot and the coil, and there is no other insulation structure between the slots of the stator slot. When the motor rotates at high speed, the high-speed airflow generated by the rotation of the motor rotor will enter Between the notch of the stator slot and the gap between the two-layer coils of the same stator slot, wind noise is formed,...
