A Motor is a device that creates motion. It usually refers to an engine of some kind. It may also specifically refer to:
Electric motor, a machine that converts electricity into a mechanical motion
AC motor, an electric motor that is driven by alternating current
Synchronous motor, an alternating current motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it
Induction motor, also called a squirrel-cage motor, a type of asynchronous alternating current motor where power is supplied to the rotating device by means of electromagneticinduction.
DC motor, an electric motor that runs on direct current electricity
Brushed DC electric motor, an internally commutated electric motor designed to be run from a direct current power source.
Brushless DC motor, a synchronous electric motor which is powered by direct current electricity and has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes.
Electrostatic motor, a type of electric motor based on the attraction and repulsion of electric charge.
Engines, which are very commonly called "motors"
Servo motor, an electric motor that operates a servo, commonly used in robotics.
Servo motor, for starting an internal-combustion engine of a vehicle.
Stepper motor, a type of electric motor capable of rotating its output shaft in equally spaced fractions of a full rotation, known as steps.
Internal fan-cooled electric motor, an electric motor that is self-cooled by a fan, typically used for motors with a high energy density.
Actuator, a mechanical device for moving or controlling a mechanism or system.
Hydraulic motor, a machine that converts the energy of pressurized liquid flow into mechanical motion.
Rocket motor, usually refers to solid rocket engines.
Molecular motor, the agents of movement in living organisms
Synthetic molecular motor, molecular machines capable of rotation under energy input.
Nano motor, a molecular device capable of converting energy into movement.
Pneumatic motor, a machine that converts the energy of compressed air into mechanical motion
"Motor Car" or "Motor", alternate terms for an automobile.
