Abstract

The invention relates to an improved motor rotor, which includes a rotor bracket, a rotating shaft, a rotor yoke, an installation unit and a permanent magnet. Two rotor brackets are symmetrically arranged and connected by bolts, and the middle of the two rotor brackets is A rotating shaft is fixedly arranged, and a rotor yoke is fixedly arranged on the outer edge of the rotor bracket. Several installation units are jointly arranged on the rotor bracket and the rotor yoke along the circumferential direction thereof, and permanent magnets are symmetrically installed on each installation unit. The present invention can solve the following problems in the current design of the motor rotor: the permanent magnets on the rotor yoke are all bonded by glue, and it is difficult to realize rapid disassembly and reinstallation, resulting in a decrease in the production and maintenance efficiency of the rotor; The number of permanent magnets on each rotor yoke is not small, and for the later maintenance of the rotor, one or more permanent magnets cannot be disassembled at the same time.

Description

technical field

[0001] The invention relates to the field of motor rotor design, in particular to an improved motor rotor. Background technique

[0002] The motor rotor is also the rotating part in the motor. The motor consists of two parts, the rotor and the stator. It is used to realize the conversion device of electrical energy and mechanical energy and mechanical energy and electrical energy. The rotor of the motor is divided into two types: the inner rotor rotation mode and the outer rotor rotation mode; The core body is a rotating body, which can output torque (referring to the motor) or receive energy (referring to the generator). The rotation mode of the outer rotor is to use the outer body of the motor as the rotating body. Different methods facilitate the application in various occasions. The present invention is aimed at the design of the rotor of a disc motor. Generally, the rotor and stator of a motor are fitted inside and outside. In order to make the disc mot...
