Problems solved by technology

Most of the traditional disk motor rotors adopt a surface-mounted structure. The magnetic steel of this structure is pasted on the surface of the rotor. Due to the centrifugal force, the surface-mounted structure cannot make the motor run at an excessively high speed, which limits the maximum speed of the motor and reduces the speed of the motor. performance
In addition, there are certain potential safety hazards in adhering the magnetic steel to the surface of the rotor. Due to the relationship of time, the glue is prone to deterioration and aging, resulting in a significant decrease in the bonding strength, and the phenomenon of magnetic steel falling off

Abstract

The invention provides a rotor structure of a disc type motor. The rotor structure comprises a rotor disc, a plurality of magnetic steels, a hoop, at least two first blocking pieces and at least two second blocking pieces, wherein the rotor disc comprises a base part and a plurality of supporting parts, the supporting parts extend outwards to the periphery of the base part, the number of the magnetic steels is consistent with that of the supporting parts, and the magnetic steels fixedly extend outwards to the base part and are arranged at intervals with the supporting parts; the hoop is fixedly arranged on the outer periphery of the magnetic steels in a sleeving manner, so that the magnetic steels are fixed between the hoop and the base part; and the first blocking pieces and the second blocking pieces are located on the two sides of the rotor disc respectively, the first blocking pieces and the second blocking pieces are fixed to the supporting parts, so that the hoop is fixedly connected between the first blocking pieces and the second blocking pieces in a clamped mode, the two sides of the hoop are connected with the first blocking pieces and the second blocking pieces in a clamped mode, so that the hoop can be fastened, and the fixing effect of the hoop on the magnetic steels is enhanced.

Description

technical field [0001] The invention relates to the technical field of disk motor rotors, in particular to a rotor structure of a disk motor. Background technique [0002] Due to the characteristics of small size, high power density, short axial dimension, and low life-cycle cost, disc motors can be used in most thin-profile installation occasions. Magnetic steel fixing plays a vital role in the smooth operation and reliability of the motor. . Most of the traditional disc motor rotors adopt a surface-mounted structure. The magnetic steel of this structure is pasted on the surface of the rotor. Due to the centrifugal force, the surface-mounted structure cannot make the motor run at an excessively high speed, which limits the maximum speed of the motor and reduces the speed of the motor. performance. In addition, the method of adhering the magnetic steel on the surface of the rotor has certain potential safety hazards. The glue is prone to deterioration and aging due to time...
