    By definition, all self-commutated DC motors run on DC electric power. Most DC motors are small permanent magnet (PM) types. They contain a brushed internal mechanical commutation to reverse motor windings' current in synchronism with rotation. A commutated DC motor has a set of rotating windings wound on an armaturemounted on a rotating shaft. The shaft also carries the commutator, a long-lasting rotary electrical switch that periodically reve
