EM-DC3 is a constant angle and constant torque stepper motor drive. The driven voltage range from DC12V to 40V. It can match 3-phase hybrid stepper motors whose rated current is under 5.8A and shaft diameter range from 42mm to 86mm. Owe to bipolar constant chopping circuit, it can make motors low noise and operated smoothly when low speed; the torque is much greater than 2-phase and 5-phase stepper motor when high speed. It is widely used in small-sized numerical control device such as medical machine, robot, instrumentation, curving machine, laser labeling machine, inner laser curving machine.
