DM542 Stepper Motor Controller

DM542 is a new type of two-phase hybrid stepping motor driver, The drive voltage of which is from 20VDC to 50VDC. It is designed for use with a 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor to run smoothly almost without noise and vibration.
