A high-speed low-loss magnetic rotor

Abstract

The invention relates to the technical field of motors, in particular to a high-speed low-loss magnetic rotor, which includes a shaft body, a rotor sleeve, an adhesive layer, a permanent magnet body, a feeding mechanism and a heat conduction mechanism. The adhesive layer is arranged on the rotor sleeve Between the permanent magnet body and the permanent magnet body, the surface of the permanent magnet body away from the rotor sleeve is provided with an outer protective layer; the present invention has a cooling function, which can reduce the influence of thermal stress on itself, make its own operation more stable, and can The permanent magnets are wear-resistant and prolong the service life of the permanent magnets, which solves the problem that the permanent magnets of some existing magnetic rotors are easily worn during the rotation process, which in turn causes the service life of the permanent magnets to be greatly reduced, and the rotor is in operation. It is easy to generate high temperature, and the rotor is affected by thermal stress and deforms, resulting in the problem that the stability of the rotor is affected. At the same time, the rotor can assist in fixing the permanent magnet, so that the permanent magnet is not easy to fall off.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-speed low-loss magnetic rotor. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. Motors are widely used in people's daily production and life. Motors are divided into DC motors and AC motors according to the type of working power supply, and can be divided into drive motors and control motors according to their uses. The magnetic rotor is usually composed of a permanent magnet and a rotating shaft. It is one of the core components of the motor. It drives the rotor core to rotate through the magnetic interaction with the magnetic stator, thereby realizing the conversion of electrical energy and mechanical energy. [0003] The permanent magnets of so...
