Stepper Motor

A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.

Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.

Famous quotes containing the word motor:

    We disparage reason.
    But all the time it’s what we’re most concerned with.
    There’s will as motor and there’s will as brakes.
    Reason is, I suppose, the steering gear.
    Robert Frost (1874–1963)
