4 Wire Stepper Motor Wiring Diagram

Bipolar stepper motors have two windings which are not connected to each other wired internally like this.

4 wire stepper motor wiring diagram. These cables are color coded such that the a wire is red the a wire is black the b wire is yellow and the b wire is purple. Stepper motor basics 4 wires bipolar motor example. It shows the components of the circuit as simplified shapes and the facility and signal connections amid the devices. Simplest to connect are 4 wire motors.

Connecting 4 wire stepper motors requires connecting a and a to one of the motor coils and b and b to the other motor coil. This is a common word during discussions involving peculiarities of step motors which can have 4 5 6 and 8 wires. The basics on how stepper motor stepper controller and stepper driver work. 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. The wire and coil pairs are called a phase. If your stepper motor has 4 wires it is a bipolar stepper motor. So do check out my other instructable videos on these motors to learn more.

4 wire stepper motor connection diagram wiring diagram is a simplified suitable pictorial representation of an electrical circuit. The 4 wires map to the 4 output pins of each stepper driver on the duet see below for identifying phases and connecting. Since coils a and b on the diagram above are not connected the resistance between leads a1 and b1 or between a1 and b2 will be infinite. The trick is figuring out which wires make up the coil pairs.
