Bipolar Stepper Motors

A Stepper Motor is a brushless DC motor that has its rotation divided into a series of steps, the motors position can be controlled by commanding it to one of these steps by means of open-loop control that does not require an encoder. This offers a cheap method of achieving a position controlled motor, however the motor must be carefully selected for its application to ensure that it has sufficient torque. To control a stepper motor you need to use a stepper motor controller, connecting a stepper motor directly to a DC power source will damage it.
We offer a quality range of bipolar stepper motors that allow you to control the position, velocity and acceleration. Why not use some of our value for money motors for precise positioning or continuous rotation applications.
