Introduction:
DQ860MA is a type of two-phase hybrid stepping motor driver, The drive voltage of which is
from 24VDC to 80VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with
57mm to 110mm outside diameter and less than 7.8A 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 DQ860MA 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, and computer embroider machine, packing machines and so on.
