stepper motor driver Q2HB44MA
Q2HB44MA(B) is a constant angle and constant torque stepper drive. The driven voltage range from DC12V to 40V. It can match 6 leads or 8 leads 2-phase hybrid step motors whose rated current under 4A, shaft diameter range from 42mm to 86m. Owe to bipolar constant chopping circuit, it can make motors lower noise, operated smoothly. It is widely used in the small numerical control device with high resolution such as curving machine, laser labeling machine and etc.
High performance, low price
12/8 channels constant angel and constant torque subdivision, highest subdivision: 200
