Descriptions

DM420 is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from 12VDC to 36VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 20mm to 42mm outside diameter and less than2.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor running smoothly almost without noise and vibration. Holding torque when DM420 driver runs under high
speed ,is also significantly higher than the other two-phase driver, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, computer embroider machine, packing machines and so on."
