3M2060H is a subdivided drive with uniform angles and constant torque, with drive voltage DC 80-220V, matching various types of three-se hybrid stepper motors with the current below 6A, OD 86 and 110MM. The drive internally adopts the servo control-like circuit, which can make the motor running at low speeds smoothly with almost no vibration and noise. Motor high speed torque is greater than other 3-se and 5-se hybrid stepper motors and traditional reaction stepper motors. When stepper pulse stops more than 100m/s, drive current will reduce by a half automatically. Positioning accuracy up to 12800 steps / cycle.
