Stepper motors (or, stepping motors) are also brushless, permanent magnet motors. They are generally 2-phase or 5-phase motors. Stepper motors are not typically servo controlled, although their position is sometimes checked with an add-on rotary encoder after the end of each move to correct for lost steps or stalls.
