Motors are one of the most widely used equipment in various sectors of the national economy. The performance of the motor shaft has a great influence on the performance of the motor and is a key component of the motor. The structure of the motor shaft is mainly composed of several (6-8) fins welded on the main shaft, silicon wafers and coils around the fins, and the magnetic field is used to generate current to work. In the operation of the motor, due to the periodic action of the motor, there is a large stress concentration in the electromagnetic force of the combination of the rib and the shaft. In addition to the conventional design of the shaft and the general process defects, fatigue cracks will occur, which will eventually lead to the fracture of the parts. invalid. Therefore, the success of the motor design depends to a certain extent on the merits of the motor shaft design. In the previous design, according to the performance requirements of the motor and the experience of designing the prototype of the motor shaft, the performance of the motor shaft was obtained through experiments; when the performance of the motor shaft did not meet the design requirements, the motor shaft needed to be adjusted to adjust the corresponding structural parameters, and then restart the test.

This repetitive cycle process makes the design cycle long and the equipment cost high. In order to solve this problem, the author uses the CAE software provided by MSC to analyze the current stress distribution and displacement deformation of the motor shaft, and comprehensively optimize the structural parameters and working performance of the motor shaft. . First use PRO-E to generate finite element analysis model, and then import ANSYS. The stress distribution is obtained by ANSYS, and then the structural parameters are adjusted by the optimization design technology to reduce the stress concentration. At the same time, the structure of the motor shaft is optimized to achieve the best performance of the motor, thereby greatly shortening the design cycle, significantly reducing the design cost, and achieving obvious economic benefits.
