Two motors for an electric lawn mower

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 electromagnetic induction
    • 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
    • Starter 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
  • Nanomotor, 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

Other uses[edit]

  • Motor language, extinct since the 1840s, a Uralic language that was spoken in the northern region of the Sayan Mountains in Siberia


  • Motor system, the physiological system that is responsible for physical movement
    • Motor neuron, neurons that originate in the spinal cord and synapse with muscle fibers
    • Motor skill, the ability of an organism to use the motor system effectively
    • Motor skill, motor created by uniten system
