Abstract

The invention discloses a rotor and a motor. The rotor comprises a rotor iron core, wherein the rotor iron core comprises a shaft ring part and a plurality of fan-shaped parts arranged around the shaft ring part at intervals, and a containing groove is formed between every two adjacent fan-shaped parts; a plurality of magnets, wherein each magnet is embedded in one accommodating groove; and damping pieces filled between the plurality of fan-shaped parts and the shaft ring part and between the magnet and the rotor iron core. According to the motor, the damping pieces are filled between the plurality of fan-shaped parts and the shaft ring part and between the magnets and the rotor iron core, so that the damping effect of the motor can be improved, and the vibration noise is effectively reduced.

Description

technical field [0001] The present application relates to the field of motor technology, in particular to a rotor and a motor. Background technique [0002] Due to its simple structure and reliable operation, DC permanent magnet brushless motors are increasingly used in various household appliances. [0003] The power density of the existing DC permanent magnet brushless motor is relatively high, and the electromagnetic force harmonics generated by it are also relatively large, so the vibration and noise caused by the electromagnetic force harmonics are more difficult to suppress. Therefore, it is necessary to design a new motor structure to alleviate or eliminate the noise caused by the vibration of the motor itself. Contents of the invention [0004] The present application mainly provides a rotor and a motor to solve the problems of poor damping effect and high vibration noise of the existing motor. [0005] In order to solve the above technical problems, a technical ...
