Introduction. Stepper motor must have a driver in order to work. Full step and half step Stepper drives control how a stepper motor operates, there are three commonly used excitation modes for stepper motors, full step, half step and microstepping.. Two-phase on provides about 30% to 40% more torque than one phase on, however it requires twice as much power from the driver. title. Controlling Step and Direction Interface Drives. Stepper motor drivers do not have any sort of on-board functions to actually make the motors spin. They are waiting for input from some other source. An inexpensive option for simple stepper motor control is a microcontroller such as an Atmel or Microchip microcontroller,. Controlling Stepper Motors with a PIC Microcontroller. Stepper Motor For applications where precise measuring of a motors' rotor position is critical, a Stepper Motor is the best choice. Stepper motors operate differently from other motors; rather than voltage being applied and the rotor spinning smoothly, stepper motors turn. As the digital pulses from the controller increase in frequency, the stepping movement converts into a continuous rotation with the velocity of the rotation directly proportional to the frequency of the control pulses. Stepper motors are widely used because of their low cost, high reliability, and high torque at low speeds.
