Description
DQ**0MA
 is a type of two-phase hybrid stepping motor driver,
the drive voltage of it is from *4VDC to
*0VDC.
It is designed for use with *-phase hybrid stepper motor of all
kinds with *7mm to **0mm 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 run smoothly almost without noise and vibration.
Holding torque when DQ**0MA
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.
