Abstract

The invention discloses a rotor and a motor. The rotor is characterized in that a rotor iron core comprises a shaft ring part and a plurality of fan-shaped parts arranged around the shaft ring part at intervals, a containing groove is formed between every two adjacent fan-shaped parts, and the shaft ring part is provided with a shaft hole; the rotor shaft is arranged in the shaft hole in a penetrating mode, and the hole diameter of the shaft hole is larger than the shaft diameter of the rotor shaft; a plurality of magnets, wherein each magnet is embedded in one accommodating groove; the damping parts are filled between the fan-shaped parts and the shaft ring part and between the rotor shaft and the inner side face of the shaft hole, the damping parts are further filled in the filling holes of the fan-shaped parts, the bonding strength of the fan-shaped parts and the damping parts is further enhanced, electromagnetic harmonics on the rotor can be reduced through the damping parts, and the service life of the rotor is prolonged. The purpose of weakening vibration and vibration noise of the rotor is achieved; and the balance holes of the fan-shaped parts can be used for correcting the dynamic balance of the rotor, so that the running stability of the rotor can be improved.

Description

[0001] This application is a divisional application with the filing date of "2019.09.26", the application number of "201910920214.3", and the application title of "rotor and motor". technical field [0002] The present application relates to the field of motor technology, in particular to a rotor and a motor. Background technique [0003] Due to its simple structure and reliable operation, DC permanent magnet brushless motors are increasingly used in various household appliances. [0004] 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. In the related art, the vibration noise is alleviated by adding filler material between the rotor core and the rotor shaft, but the overall bonding strength of the rotor is poor, which reduces the running stability of...
