Problems solved by technology

[0002] With the understanding of the characteristics of DD motors (direct drive motors), drum washing machines gradually adopt DD motors as driving components. DD motors are usually external rotor motors with large rotor diameters. Therefore, the structural rigidity and strength of the rotor has become a difficulty in the application of DD motors. , the DD motor in the related art, the structural rigidity and strength of the rotor are not ideal, it is prone to bending or buckling in the process of production and use, and the accurate alignment with the stator cannot be guaranteed

Abstract

The invention discloses a rotor for a motor, a motor and a washing machine. The rotor for the motor comprises a hub used for connecting the rotor with a rotating shaft of the motor; a peripheral portion for interacting with a stator of the motor to make the rotor rotate about an axis of rotation; a spoke connected between the hub and the peripheral portion, wherein an inner peripheral edge of thespoke connected to the hub is configured as a wave shape undulating in an axial direction of the hub and continuously extending in a circumferential direction of the hub. According to the embodiment of the invention, the rotor for the motor has the advantages of high structural rigidity and strength, capability of ensuring accurate alignment with the stator and the like.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a rotor for a motor, a motor with the rotor for a motor, and a washing machine with the motor. Background technique [0002] With the understanding of the characteristics of DD motors (direct drive motors), drum washing machines gradually adopt DD motors as driving components. DD motors are usually external rotor motors with large rotor diameters. Therefore, the structural rigidity and strength of the rotor has become a difficulty in the application of DD motors. In the DD motor in the related art, the structural rigidity and strength of the rotor are not ideal, and it is prone to bending or buckling in the process of production and use, and the accurate alignment with the stator cannot be guaranteed. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention p...
