Insulation frame of motor for washing machine, stator assembly, motor, washing machine

Abstract

The invention discloses an insulation frame, a stator assembly, a motor and a washing machine of a motor for a washing machine. The insulation frame comprises a first insulation skeleton, wherein thefirst insulation skeleton is adapted to be installed on one shaft end of a stator iron core of the motor; a second insulation skeleton which is adapted to be installed on one shaft end of the stator iron core of the stator; a third insulating connection frame through which the first insulation skeleton and the second insulation skeleton are connected, wherein, the third insulating connection framecomprises a plurality of insulating inserted rods arranged in an annular shape and spaced apart, each of the insulating inserted rods is adapted to be inserted at a slot of a stator slot of the stator core. The insulation frame of the motor for a washing machine according to the embodiment of the invention avoids the wind noise generated by the rotation of the motor rotor, improves the safety performance, has a simple structure, is convenient to install, and has good user experience.

Description

technical field [0001] The invention relates to the technical field of clothes processing equipment, in particular to an insulating frame for a washing machine motor, a stator assembly, a motor, and a washing machine. 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 sam...

[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
