DC motors are electrical motors powered by direct current, or DC. DC is a type of electrical current that flows in one direction only, from sources such as batteries or solar panels. DC may also be produced through the use of a rectifier, which is an electrical device which converts alternating current (AC) to DC. This module will describe the design, operation, and applications of series, shunt, compound, permanent magnet, and separately excited motors.
