[0002] In the prior art, in order to reduce the rotational speed and increase the torque, mechanical equipment usually connects a reducer to the motor to form a reduction motor. Reducer motors are widely used in robotic arms due to their compact structure, small size, light weight, high transmission efficiency, large output torque, and smooth operation. When the robotic arm is in use, it is often necessary to ensure accuracy within the working range.
