[0002] A two-phase hybrid stepper motor control system is a device that can control a two-phase hybrid stepper motor. It is mainly composed of a housing, a control circuit board, and wiring terminals. There are still some problems in the actual use of this device.

After the power is cut off, there will be residual electricity in the circuit board. Therefore, the staff may be electrocuted by the circuit board during the cleaning process, and the use safety is low. Utility Model Content
