Abstract

The invention discloses a rotor and a motor. The rotor comprises a rotor iron core, a plurality of magnets and a plastic-coated part, 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 to form a plurality of containing grooves; each magnet is embedded in the corresponding accommodating groove; the plastic coating part coats the magnet and the rotor iron core; the plastic-coated part comprises an end face covering part and a side face filling part, the end face covering part covers the magnet on the end face of the rotor core, and the side face filling part is connected with the end face covering part and the magnet covering the side face of the rotor core, so that the stability of the rotor during operation is improved, and the performance of the motor is improved.

Description

[0001] The present invention is a divisional application with an application date of "2019.9.26", an application number of "201910919368.0", and an application name of "rotor and motor". technical field [0002] The present invention relates to the technical field of motors, in particular to a rotor and a motor. Background technique [0003] DC permanent magnet brushless motors are more and more used in various household appliances because of their simple structure and reliable operation. The permanent magnet rotor of the brushless DC motor rotates at high speed due to the centrifugal force, so the assembly between the rotor shaft, the rotor iron core and the magnet is the key to the stable output power of the rotor, and the assembly stability of the rotor is the key to the brushless DC motor. Urgent problem to be solved. SUMMARY OF THE INVENTION [0004] The present invention mainly provides a rotor and a motor to solve the problem of poor rotor stability. [0005] In o...
