Description

Technical Field

[0001] The utility model belongs to the technical field of washing machine motors, in particular to a vibration-absorbing and noise-reducing washing machine motor end cover. Background Art

[0002] A washing machine is a common household appliance. The motor drives the drum to rotate, causing the clothes to tumble and rub back and forth, thereby removing stains from the clothes. The motor is the core component of the washing machine.

[0003] The core component of the washing machine is the motor. The high-speed operation of the motor will inevitably generate noise. The main source of noise in the motor is the tight contact between the stator steel sheet and the end cover. This contact will have dislocation, causing abnormal noise, thereby increasing the noise of the motor. For this reason, we propose a shock-absorbing and noise-reducing washing machine motor end cover. Utility Model Content
