A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years ...
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.

The Lynch motor is a unique axial gap permanent magnet brushed DC electric motor. [1] The motor has a pancake-like shape and was invented by Cedric Lynch in 1979, the relevant patent being filed on 18 December 1986.

In an ordinary automobile, 50 to 60 small motors control everything from door locks and power windows to power seats, steering locks, air conditioner dampers, car mirrors, head lamps, navigation systems and audio visual equipment. [22] But in a luxury car like the one Takaichi and Shinji were riding in, over 100 small electric motors are used. [22]
Servo motors and stepper motors are specialist types of fractional-horsepower electric motors usually intended for high-precision or robotics applications. Usually running from a DC supply, when combined with a planetary gearbox can offer accuracies less than 8 arc-minutes (2 ⁄ 15 ths of a degree, or approx. 2.3 milliradians). Due to their ...
