Stepper motor wiring tutorial - 42bots Nov 22, 2014Pingback: Arduino Bipolar Stepper Motor -Use Arduino for Projects. Pingback: Bipolar stepper motor control with Arduino and an H-Bridge. Madhukar Saran December 18, 2017. I have 8 wire (4 coils) stepper motor. IOt is mentioned as 100V, 50/60 Hz. How do i connect to power to rotate uni-direction or if i can use it as bi direction. Stepper Motor Basics - 4 Wires Bipolar Motor STEPPER MOTOR BASICS - 4 WIRES BIPOLAR MOTOR example. The basics on how stepper motor, stepper controller, and stepper driver work. NOTE: There are slight differences on how the different variant of stepper motors work (i.e. the 4 wires, 5 wires and 6 wires stepper motors). So do check out my other instructable videos on these motors to learn more.
