Constant angle, constant torque micro step driver, the drive voltage of which is from 12V to 40VDC. It is designed for use with 2 phase hybrid stepper motor of all kinds with 42mm to 57mm outside diameter, 6, 8 leads, regulated phase current from 0.5A to 3A. 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 small size of numerical control devices with higher resolution such as carving machine, laser labeling machine, inner laser curving machine and etc.
