The distinction between AC and DC motors has become blurred as controllers for DC motors make increasing use of pulse-width modulation, which can be viewed as a form of alternating current. All motors that consume DC power are referenced in the DC motor section of this encyclopedia, regardless of whether they modulate the power internally. Stepper motors and servo motors are considered as special cases, each with its own entry. AC motors, described here, are those that consume alternating current, usually in the form of a sine wave with a fixed frequency.
