[0002] The control of motor vibration and noise is an important issue faced by environmental protection, and it is also an important link to improve the competitiveness of motor products in domestic and foreign markets. Obtaining motor vibration characteristics is a key technology for low-noise motor design; due to the complexity of the motor structure, Especially in the working state, its vibration research involves the intersection and integration of multiple disciplines such as electromagnetism, mechanics and thermals, which also brings certain challenges to the research on the vibration characteristics of motors; at present, domestic and foreign research on motor vibration A large number of studies on the characteristics of the motor are mainly concentrated on the motor components (such as the base, iron core and stator) or the free state of the whole machine, and there is almost no research on the vibration characteristics of the motor in the working state; however, only the vibration of the motor in the working state is mastered. In order to truly understand the actual vibration state of the motor, it can provide a practical and effective scientific basis for the low-noise design of the motor;
