Problems solved by technology

This structure transfers the heat generated by the stator assembly to the first end cover through the heat-conducting glue on the inner wall of the end cover, and then conducts the heat to the outside through the first cooling channel. The indirect heat-conducting structure has a good heat dissipation effect. not obvious

Abstract

The invention belongs to the technical field of motors, and particularly relates to a fixing structure for magnetic steel of a rotor of a disk-type motor. The fixing structure comprises two end coversand a bearing disk; the two end covers are fixedly arranged at the two sides of the bearing disk respectively, shaft holes are formed in the centers of the end covers and the center of the bearing disk, a plurality of magnetic steel holes are uniformly formed in the bearing disk in the circumferential direction, and the magnetic steel is arranged in the magnetic steel holes; the end covers are provided with a plurality of observation holes, the number of the observation holes is equal to that of the magnetic steel holes, the observation holes correspond to the magnetic steel holes in position, and the sizes of the observation holes are smaller than those of the magnetic steel holes. The fixing structure is simple in manufacturing process and good in heat dissipation performance, and the working state of the magnetic steel is convenient to observe.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a magnetic steel fixing structure for a rotor of a disc 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 to the surface of the rotor has certain potential safety hazards. The glue is prone to deteri...
