motor

Physics

Any device for converting chemical energy or electrical energy into mechanical energy. See electric motor; internal-combustion engine; linear motor.

Chemical Engineering

A machine that converts electrical or chemical energy into useful work. Pumps used to transport fluids are driven by electric motors, which convert electrical energy into mechanical energy. A simple form of electric motor uses electric current to power a set of electromagnets on a rotor in the magnetic field of a permanent magnet. An internal combustion engine is also a motor in which fuel is combusted with oxygen in the form of air and converted to useful mechanical energy.

Electronics and Electrical Engineering

A machine that converts electrical energy into mechanical motion. The motion is produced by the torque due to the magnetic fields associated with the currents in the windings (see also electromagnetic induction).
An alternating-current (a.c.) motor operates with an alternating-current power supply. The rotating parts are termed the armature (or rotor) and the stationary windings the stator. A direct-current (d.c.) motor operates with a direct-current power supply and usually contains a commutator that connects each of the sections of the primary winding in turn to the power supply in order to provide the necessary torque. See also induction motor; synchronous motor.
