Model No.:DQ542MA

Suitable for NEMA 17, NEMA 23 series


Dimension : 

DC Gearmotor | Planetary Gearbox



DQ542MA is a type of two-phase hybrid stepping motor driver, the drive voltage of it is from 18VDC to 50VDC. 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. 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. Holding torque when DQ542MA runs under high speed is also significantly higher than the other two-phase driver, wh's more, the positioning accuracy is also higher. It is widely used in middle and big size numberical control devices such as curving machine, CNC machine, Computer embroider machine, packing machines and son on.
