2-Phase Stepper Motor Driver

Q2HB44MD is a Constant angle, constant torque micro step driver, the drive voltage of which is from 12V to 40VDC. It is designed for use with the 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter, 6, 8 leads, regulated phase current from 0.5A to 4A . The unique control circuit that it adopts can reduce motor’s noise, make motor run more smoothly, improve motor’s performance by 30% at high speed, reduce driver’s heating by 50%. It is widely used in the small numerical control devices with high resolution such as curving machine, laser labeling machine and etc.
