in stock by dhl new leadshine 2 phase stepper drive nd2278 work 220 vac out 7.8a updated from old drive md2278

stepper motor is prone to resonance if not properly controlled; 2, it is difficult to run to a higher speed; 3. it is difficult to obtain a large torque; 4. there is no advantage in terms of volume and weight, and energy utilization is low; 5. when the load is exceeded, the synchronization will be destroyed, and vibration and noise will be generated when working at high speed. , rai, ra2 control the three phases of the stepper motor.
