DQ542MA Stepper Motor Driver

SKU: E084
  • DQ542MA is a type of two-phase hybrid stepping motor driver

    It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current.  

    The circuit that it adopts is similar to the circuit of a servo controller which enables the motor to run smoothly almost without noise and vibration!

    Holding torque when DQ542MA is run under high speed is also significantly higher than the other two-phase driver, what’s more, the positioning accuracy is also higher.


    •   High performance, low price
    •   Average current control, 2-phase sinusoidal output current drive
    •   Supply voltage from 18VDC to 50VDC
    •   Opto-isolated signal I/O
    •   Overvoltage, under voltage, overcorrect, phase short circuit protection
    •   15 channels subdivision and automatic idle-current reduction
    •   8 channels output phase current setting
    •   Offline command input terminal
    •   Motor torque is related with speed, but not related with step/revolution
    •   High start speed
    •   High holding torque under high speed
