This allows for the assessment of the motor's electrical and mechanical performance and the timely detection of potential faults or defects. Existing motor power-on testing devices are often complex to operate and lack stability, making them prone to loosening or falling off during testing, which affects the accuracy and safety of the test. Therefore, a new motor power-on testing device is needed. Chinese patent provides a motor power-on testing device, publication number CN220855118U, which includes a support frame. The support frame is equipped with a first drive mechanism and a second drive mechanism. The output end of the first drive mechanism is connected to a pressing mechanism, and the pressing mechanism is connected to a probe holder. A third drive mechanism is disposed below the pressing mechanism. The output end of the third drive mechanism is connected to a shaft mounting block, and the shaft mounting block is connected to a bushing for fixing the motor. An encoder is connected below the bushing, and the bushing is located below the probe holder. The output end of the second drive mechanism is connected to a grounding probe facing the pressing mechanism.

[0003] The above-mentioned device is convenient to use, highly automated, efficient, time-saving, and labor-saving, greatly reducing labor costs. However, when using the device, after placing the motor to be tested, the motor needs to be tested and run.
