Abstract

The present invention relates to a rotor for a disk motor, the disk motor and a vehicle. The rotor for the disk motor comprises a rotor bracket, a plurality of magnetic steel grooves for mounting magnetic steels are circumferentially distributed on the rotor bracket, the magnetic steels are installed in the magnetic steel grooves, a pressing fixing member is arranged between two adjacent magneticsteels and has an overhanging pressing portion for pressing two adjacent magnetic steels, and the pressing fixing member is fixedly connected to the rotor bracket through a fastener. According to therotor for the disk motor, the pressing fixing member is arranged between the adjacent magnetic steels and has the overhanging pressing portion for pressing the two adjacent magnetic steels, the circumferential direction positioning of the magnetic steels is achieved by the magnetic steel grooves, the axial positioning of the magnetic steels is achieved by the magnetic steel grooves and overhangingpressing portions of pressing fixing members, the assembly method is simple, the matching surfaces of the magnetic steel grooves, the magnetic steels and the pressing fixing members are straight, theprocessing technology is simple, and the accuracy can be guaranteed.

Description

technical field [0001] The invention relates to a rotor of a disc motor, a disc motor and a vehicle. Background technique [0002] Disc motor is also called disc motor, which is different from the radial magnetic field of the traditional cylindrical motor. The air gap of the disc motor is flat, and the air gap magnetic field is axial. It has the characteristics of small size, light weight and simple structure. At the same time, it also has the advantages of high power / volume ratio, high power factor, and small required inverter capacity. It is a widely used motor. At present, the stator of most disc motors is a coil, and the rotor is a disc equipped with magnets or permanent magnets. The fixing form of the magnets on the rotor will affect the production and processing progress of the entire rotor and the magnetic flux rate on the rotor surface, thereby affecting The performance of the whole motor and the promotion and application of the disc motor. [0003] The Chinese pat...
