1, can open loop control in digital signal directly, the whole system is simple and cheap, displacement and number corresponding to the input pulse signal, interval error accumulation for a long time, not the open loop control system is simple and has a certain accuracy; In demanding higher precision, also can be used in a closed loop control system. 2, as a result of the step motor brushless, therefore less body parts, high reliability. 3, easy to start, stop, turn positive and negative, good speed response; Stop when the self-locking ability in general. Step 4, from the Angle of can choose on a larger scale, in the case of small step distance, can under low speed high torque and stable operation, without reducer direct drive load. 5, the speed can be adjusted over a wide range smoothing, also can use a controller to control a few devoted into motor synchronous operation completely. 6, step motor with inertia load ability is bad, because there are out of step and resonance problem, step motor deceleration method under different application condition, situation is more complicated. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
