Problems solved by technology

Although this structure further reduces the occupied space to a certain extent, because its principle is to use the inner circumferential space of the stator of the outer rotor motor to install the reduction mechanism in the inner diameter space of the stator through the installation parts, it cannot be used in the inner rotor without inner space. The application on the motor has certain limitations. At the same time, the motor body directly drives the shaft, and then decelerates the drive shaft through the reduction mechanism installed in the inner diameter space of the motor, so it only reduces the occupied space to a certain extent, but the structure It is still not compact enough. Furthermore, when the volume of the reduction mechanism needs to be increased in order to obtain a larger transmission ratio, the outer rotor motor must also increase the volume of the inner diameter to realize this invention. Obviously, this does not solve the essential technical problem
[0004] In addition, the direct connection of the motor and the reduction mechanism in the prior art, in order to meet the starting torque and maximum torque required for the operation of the mechanism, the motor needs to use an external rotor motor, generally a DC brushless or permanent magnet synchronous motor, which requires expensive Permanent magnet materials, resulting in very high cost of motor occupation

Abstract

The invention relates to a motor assembly for a vertical axis washer. The vertical axis washer comprises a wash actuator fixedly connected with a wash shaft and a dewatering actuator fixedly connected with a dewatering shaft sleeve. The motor assembly comprises a motor, a reduction mechanism connected with the motor, the wash shaft, the dewatering shaft sleeve, and a clutch device, wherein the wash shaft and the dewatering shaft sleeve are connected with the reduction mechanism and the clutch device is used for switching washing and dewatering modes. The motor assembly is characterized in that the motor is an eight-pole induction motor. The eight-pole induction motor comprises a stator component and a rotor component mounted within the stator component. Rotation axis of the rotor component overlaps with axis of the wash shaft. The motor assembly fully satisfies maximum torque and starting torque required by mechanism operation, enables manufacturing cost to be greatly lowered and is low in noise.

Description

technical field [0001] The invention relates to a motor assembly for a vertical shaft washing machine. Background technique [0002] Ordinary motors have a high speed. In order to obtain a suitable output speed, the motor needs to be decelerated in practical applications. At present, the commonly used method is to transmit the motor to the reducer and decelerate through the first-stage pulley, and set a first-stage pulley in the reducer. Or multi-stage gear reduction mechanism to complete the deceleration of a certain speed ratio. This structure is not only complicated, but also takes up a lot of space. In order to solve this technical problem, there are currently some proposals to remove the pulley and directly connect the motor and the reducer. Since the motor body and the reducer are still relatively independent, the motor body and the reducer need to occupy installation space respectively, and the structure is not enough. Compact and still bulky. [0003] In order to ...
