Stepper Motor

Stepper motors are used when accurate positioning is required. Controlling the position of a stepper motor is achieved by energizing stator windings that allow the stator to align with permanent magnets mounted on the rotor. The MCU controls the sequence of pulses that are applied to the windings to control speed and direction.
