[0002] Due to the rotation of the motor rotor, the motor will generate a certain vibration. Therefore, it is necessary to conduct vibration testing on the motor. During motor vibration testing, the motor wires are connected to a high-precision electrical inspection device, and the motor is made to work. The electrical inspection device collects the vibration data of the motor during operation. During vibration testing, it is necessary to support and place the motor without fixing it rigidly. The fixture for placing the motor needs to be able to provide positioning support for the motor during operation and also provide room and space for vibration.

[0003] Currently, the fixtures used for motor vibration testing have unstable positioning accuracy. For one type of machine model, a dedicated placement fixture needs to be configured, and there are too many fixture styles to be commonly used with other machine models. When conducting vibration testing on different machine models, it is not convenient to switch, and the switching accuracy is unstable, resulting in a relatively high misdetection rate for the motor. In addition, there are too many styles of placement fixtures, which is not conducive to equipment standardization and also results in higher costs. Summary of the Utility Model
