Problems solved by technology

[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, which makes the motor generate noise, and the distance between the two-layer coils in the same stator slot near the slot is relatively close. When the motor is in a bad environment Or when the air is humid, it is easy to short circuit between phases, resulting in overcurrent of the motor and a fire hazard. Therefore, there is room for improvement

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.
