[0044] Figure 1a This is a schematic structural diagram of a system for detecting the stability of a motor provided in the first embodiment of the present invention. This system is suitable for detecting the stability of the motor operation. The system for detecting the stability of the motor provided in this embodiment includes: a drive module 1, a drive shaft 2 and a test module 3.

[0045] Among them, the driving module 1 is respectively connected with the motor 4 and the transmission shaft 2 to be tested, and is used to drive the transmission shaft 2 to rotate under the driving of the motor 4 to be tested; The rotation frequency of φ detects the stability of the motor 4 to be tested.

[0046] Specifically, when the motor 4 to be tested is powered on, it can drive the transmission shaft 2 to rotate through the drive module 1 connected to it. In actual situations, when the drive shaft 2 rotates, it can drive the belts in the equipment to move. For example, the d
