According to the information of the State Intellectual Property Office on April 26, 2025, Anhui VOOFU Permanent Magnet Technology Co., Ltd. has applied for a patent named "a mechanical weak magnetic speed regulation permanent magnet motor" with the publication number CN119865021a and the application date of March 2025.
The patent abstract shows that the invention discloses a mechanical flux-weakening speed regulation permanent magnet motor, which belongs to the technical field of permanent magnet motors and comprises a motor body, wherein both sides of the motor body are respectively provided with an exhaust hole group and an air inlet hole group, the inside of the motor body is rotatably connected with a rotating shaft, the inner side wall of the motor body is symmetrically provided with stator discs, The surface of the rotating shaft is connected with two groups of symmetrically designed permanent magnet rotors through a sliding rail in a sliding way, and one side of the stator disc close to the permanent magnet rotors is provided with a plurality of groups of coil assemblies along a ring shape. According to the invention, when the rotating speed of the motor body is increased, the centrifugal force on the sealing piston block and the clump weight is changed through the rotating speed change of the rotating shaft, and the pressure change in the sealing cavity is controlled, And that stability and the safety of the operation of the motor body are effectively ensure.
