• 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
