Abstract

The invention discloses a permanent magnet motor rotor, relates to a motor rotor structure and solves the problems that the fixation of a permanent magnet is not facilitated because the magnet yoke of the conventional rotor needs to be spliced, and the process is complex. The permanent magnet motor rotor comprises a rotor magnet yoke and the permanent magnet, wherein the rotor magnet yoke is a cylinder, the permanent magnet is fixed on the outer surface of the side face of the rotor magnet yoke, and the rotor magnet yoke is a nodular cast iron rotor magnet yoke. Compared with the prior art, the permanent magnet motor rotor is beneficial to the installation and fixation of the permanent magnet, and the cost is low.

Description

technical field [0001] The invention relates to a motor rotor structure. Background technique [0002] With the development of permanent magnet motor manufacturing technology and its control technology, permanent magnet motors, especially high-power permanent magnet motors, have gradually replaced asynchronous motors and are widely used in various industrial fields. The rotor is the main component of the permanent magnet motor, the rationality of its structural design and the simplicity of the process have an important impact on the manufacture and stable operation of the motor. At present, the rotor structures of permanent magnet motors mainly include surface mount type and built-in type. [0003] Although the permanent magnet is installed firmly in the embedded structure, the process is complicated. Therefore, the surface-mounted permanent magnet motor with simple structure and low cost is more widely used. The yoke of the surface-mounted magnetic steel structure motor ...
