The torque sensor 28 can be the LH-903C model of the force constant sensor, which has high precision and torque A connecting component is provided on the side of the sensor 28, which enables the driven wheel 30 to rotate together with the driving wheel 21. The user can drive the external transmission device of the driven wheel 30. The base 10, the driving wheel 21, the driven wheel 30 and the torque sensor 28 are penetrated by the same set of rotating rods 35. An installation cavity 15 is provided at one end of the base 10. The detection component includes a control module 16 and an accelerometer 17. The control module 16 can adopt the MYC-YA15XC-T model of Mil Electronics, which has a strong processing capability. The accelerometer 17 can adopt the OMEGAROMETER series of OMEGA, which has good measurement accuracy and can adapt to harsh environments. The control module 16 and the accelerometer 17 are both installed in the installation cavity 15. The detection component also includes an alarm light 11, which is provided at one end of the base 10.

[0025] The user can set the threshold values ​​of torque and vibration through the control module 16. After the setting is completed, when the clutch is working, the accelerometer 17 converts the clutch vibration value into an electrical signal and sends it to the control module 16. The torque sensor 28 converts the torque value of the rotating rod 35 into an electrical signal and sends it to the control module 16. The control module 16 then processes and judges the sent electrical signals in real time. When the vibration value or torque value exceeds the threshold value set by the user, the control module 16 controls the alarm light 11 to start, reminding the user that the clutch has failed. At the same time, the control module 16 controls the power supply phase sequence of the stator winding 20, so that the rotor winding 23 generates an opposite force, causing the drive wheel 21 to stop.

The metal sheet 26 contacts the friction plate 25, increasing the friction force, so that the driving wheel 21 can drive the driven wheel 30 to rotate in the same direction. When the work stops, the powerful electromagnet 24 is powered off, the metal sheet 26 and the powerful electromagnet 24 are cancelled. The telescopic rod 27 drives the metal sheet 26 to reset, so that the driven wheel 30 stops rotating.
