Abstract

The invention belongs to the field of motors, and relates to a disc-type permanent magnet motor rotor. A permanent magnet is generally fixed on a motor metal magnetism baffle plate of the conventional disc-type permanent magnet motor by adopting adhesive, and the connection mode greatly affects the improvement on power density, efficiency and using reliability of the motor. In order to overcome the defects of the conventional disc-type permanent magnet motor, the invention provides a disc-type permanent magnet motor rotor structure. For solving the technical problems, the invention adopts the technical scheme that the permanent magnet is fixed on the motor metal magnetism baffle plate by adopting press blocks and screws so that the permanent magnet is fastened and connected with the motor metal magnetism baffle plate, the connection reliability is greatly increased and the power density and efficiency of the motor are improved. The disc-type permanent magnet motor rotor consists of a motor rotating shaft assembly and a rotor disc assembly. The motor rotating shaft assembly consists of a motor rotating shaft and fixing nuts. The rotor disc assembly consists of the motor metal magnetism baffle plate, the permanent magnet, the press blocks and the screws.

Description

technical field [0001] The invention belongs to the field of motors, and relates to a motor rotor, in particular to a composition method and structure of a disc permanent magnet motor rotor. Background technique [0002] The existing traditional disc-type permanent magnet motors mostly use adhesives to fix the permanent magnets to the metal magnetic shield of the motor.
