There are two main types of stepper motors – unipolar and bipolar. Both types have their own advantages and disadvantages, so it’s important to know which one is best for your application.
Unipolar stepper motors are the most common type of stepper motor. They are cheaper and easier to control than bipolar stepper motors, but they have some drawbacks. Unipolar stepper motors can only be used with certain types of controllers, and they have a lower maximum torque than bipolar stepper motors.
Bipolar stepper motors are more expensive and harder to control than unipolar stepper motors, but they have some advantages. Bipolar stepper motors can be used with any type of controller, and they have a higher maximum torque.
So, which type of stepper motor is best for your application? It depends on your needs. If you need a high maximum torque, then a bipolar stepper motor is the best choice. If you need a lower cost and easier control, then a unipolar stepper motor is the best choice.
