Abstract

The invention discloses an axial magnetic field motor rotor, and a forming process thereof. The forming process of the axial magnetic field motor rotor includes the steps: putting and fixing magneticbodies in a die according to a preset arrangement mode; and in a mode of injection moulding or prepreg stacking and hot pressing, realizing forming of a holder in the die, and fixedly pre-embedding the magnetic bodies in the holder during the forming process. The forming process of the axial magnetic field motor rotor can eliminate the assembling gap between the magnetic bodies and the holder in the axial magnetic field motor rotor, reduces the dynamic balance deviation of the axial magnetic field motor rotor, enhances the integral rigidity of the axial magnetic field motor rotor, is conductive to reduction of the processing time and the mechanical processing cost, and can improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an axial field motor rotor and a forming process for the axial field motor rotor. Background technique [0002] The axial field motor has the characteristics of small size, light weight and high efficiency. The stator of the axial field motor is generally a coil, and the rotor is a permanent magnet. [0003] The traditional manufacturing method of the motor rotor is to mount the magnets on the cage by gluing. This manufacturing method not only has many production processes and low assembly efficiency, but also has high requirements for the processing accuracy of the magnet and cage and the operation process during installation, and because of the manufacturing process, the magnet and cage after assembly There will be more or less assembly gaps between them, resulting in large deviations in the dynamic balance of the rotor and low overall rigidity. [0004] Therefor...
