In summary, stepper motors are ideally suited for applications that require precise position control such as computer peripherals or numerically controlled machine tools. The two common configurations for stepper motors include bipolar and unipolar, and use half-step, full-step, or microstepping driving techniques. Each driving circuit will consist of the step time and phase generator (which is usually done in a microcontroller), the PWM current control, and the power bridge. Finally, when creating a stepper motor driver, the designer must consider the speed-torque performance of the motor.
