In order to improve the reliability of mining electrical equipment and realize intelligence of the separation test of the coal mine isolation switch operation process, the motor mechanism is put forward. We designed controllable testing system based on coal mine isolation switch breaking test the existing operating mechanism including three-phase bridge driver circuit, position and stroke detection circuit, and testing in the way of different duty than the single test. The test results show that the slope (velocity) of the curve is changed with the duty cycle, which proves the controllability of the running process of the motor mechanism.
