4 Wire Stepper Motor Wiring Diagram

Inside the stepper motor are two coils each coil having a wire connected to each end.

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. The basics on how stepper motor stepper controller and stepper driver work. But today i can say that this type of engine is no longer such a difficult challenge as they are starting to get more a.

The wire and coil pairs are called a phase. Bipolar stepper motors have two windings which are not connected to each other wired internally like this. This is a common word during discussions involving peculiarities of step motors which can have 4 5 6 and 8 wires. The 4 wires 5 wires and 6 wires stepper motors.

So do check out my other instructable videos on these motors to learn more. The trick is figuring out which wires make up the coil pairs. 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.

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. 4 wire stepper motor connection diagram wiring diagram is a simplified suitable pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes and the facility and signal connections amid the devices. If your stepper motor has 4 wires it is a bipolar stepper motor.
