Problems solved by technology

At home and abroad, the photoelectric torque measurement method is mainly used in the measurement of the small output torque of the motor, but its support mechanism cannot realize the measurement of the output torque of a variety of different types of motors, basically only for a certain type of motor. Measurement of Micro Moments
The tooling of different motors has certain differences. Considering the inconsistency of the tooling in the design of the motor, the outer diameter of different types of motors will change to a certain extent, so it is necessary to frequently replace the motor support mechanism, or according to different The corresponding test platform is processed by the motor, which will inevitably increase the design cost and occupy a large experimental space
