Nema 17 Stepper Motor Wiring Diagram
Tips: Whether the subdivision number of subdivided driver can represent accuracy?
4-phase hybrid stepper motor is generally started with 2-phase driver. Therefore, 4-phase motor can be used after connecting into 2-phase one through series or parallel connection. The series connection is generally used when the motor generally rotates at low velocity. At this time, the output current of driver should be 0.7 times of phase current of motor. Therefore, motor heating is small. By contrast, the parallel connection is generally used when the motor rotates at high velocity (also called high-velocity connection). At this time, the output current of the driver should be 1.4 times of the phase current of the motor. Therefore, the motor heating is large.
