Nema 8 Micro Stepper Motor Details

Tips: Nema 8 micro stepper motor maintenance.

Zero excitation maintenance: maintain the Nema 8 micro stepper motor with an excitation circuit formed by a current relay.
Over-voltage maintenance: maintain the Nema 8 micro stepper motor with an armature circuit composed of over-voltage relay.
Overload protection: use an armature circuit composed of a current relay to maintain the Nema 8 micro stepper motor.
Overcurrent protection: use an armature circuit composed of overcurrent relay to maintain the Nema 8 micro stepper motor.
Grounding maintenance: Use a grounding device formed by voltage relay to maintain the Nema 8 micro stepper motor. When any point of the DC motor is grounded, the voltage relay will act to send out a warning signal or cut off the power supply.
