外文摘要：With the widespread use of variable frequency motors in the robotics industry, the issue of their vibration and noise has gradually attracted the attention of scientists. Electromagnetic waves are one of the main excitation sources that cause electromagnetic vibration in variable frequency speed control motors, which directly affects the amplitude and frequency distribution of the vibration. In general research, it is only analyzed as a general excitation source. This paper focuses on the radial electromagnetic waves of small and medium-sized motors, and analyses the radial electromagnetic force using analytical and finite element methods. When compared with the vibration response, the frequency spectrum of the electromagnetic waves is consistent with that of the vibration response. This indicates that in small- and medium-sized motor structures with high rigidity, the main source of vibration in the entire machine is electromagnetic vibration. Therefore, by analyzing the electromagnetic excitation, the motor vibration can be better predicted. ? 2023 IEEE.
