Abstract

The invention provides a rotor structure and a motor with the same. The rotor structure includes a rotor core, a plurality of permanent magnets and a locking assembly. The permanent magnets are inserted into the rotor core at intervals along the circumference of the rotor core. The locking assembly includes a first locking member and a second locking member, which are matched with each other and are located at the two ends of the rotor core respectively. Part of the first locking member passes through the rotor core and is connected with the second locking member to fasten the permanent magnets inside the rotor core. The problem that the rotor structure has low reliability and a complex production process due to the fact that the permanent magnets are fixed with glue is solved. The rotor structure of the invention is simple in production process and convenient to rework and maintain. The production efficiency is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotor structure and a motor having the same. Background technique [0002] According to the arrangement of permanent magnets on the rotor, permanent magnet synchronous motors are mainly divided into two types: surface mount type and embedded type. The surface mount type is to attach the permanent magnet to the surface of the rotor, and the structure is relatively simple; the embedded type is to embed the permanent magnet inside the rotor core, the structure is more compact, the pole arc coefficient is easy to control, and each pole can provide greater magnetic flux. [0003] The permanent magnets embedded in the rotor core are usually fixed with glue or covered with plastic. When the rotor poles of the embedded permanent magnet motor have a large number of rotor poles, the magnetization of the rotor becomes a bottleneck problem. The magnetism is fixed by glue, and the ...
