Direct Current Electric Motors

A DC motor's primary function is to convert electric power into mechanical energy. This is possible by forcing current through a coil and producing a magnetic field that spins the motor.
A DC Motor is a device that runs on Direct Current from a battery or from DC supply. DC motor is a single coil apparatus which has the internal configuration designed to harness the magnetic interaction between a current-carrying conductor, and an external magnetic field to generate rotational motion.

The applications of the DC Motors are found in VCR, elevators, CD players, toys, robots, watches, automobiles, subway trains, fans, space ships, air conditioners, refrigerators, and many other places. When D.C. power supply is connected between a D.C. motor's electrical leads, the motor converts electrical energy to mechanical work, which results in shaft turns to provide the needed variable output. The DC electric motor is the most convenient of all sources of motive power, this motor is clean and silent, which is capable enough to start instantly, and can be built large enough to drive the world's fastest trains.
