[0005] In summary, the utility model has the following beneficial effects: the motor and the motor shaft rotate relative to each other, the abutment joint rubs against the inner wall of the inner ring and deforms accordingly, and transmits force to the sensing plate, and the sensing plate monitors the torque change by sensing the deformation of the sensing plate. Since the torque sensing structure is integrated with the motor, monitoring can be started at the transmission end. Since the torque sensing structure is integrated inside the motor, the torque sensing structure is protected from external interference or even damage, ensuring that more accurate monitoring information can be obtained.
