A part inside a motor that turns inside the fixed outer part to make or use electricity
  • noun
  • /ˈroʊtər/
  • Specialized
translation icon : rotor
  • The generator itself has two basic parts: the stator, which is stationary, and the rotor, which rotates.
  • rotor and stator
  • motor rotor
  • generator rotor

Now this will start to give us some clues to why I can just pivot my hand like this and it speeds up the rotor inside.

Examples

  • When the rotor turns, it creates a magnetic field that powers the generator's output.

  • The only moving part is the motor rotor, which is mounted on magnetic bearings.

    Academic text (1996)

  • Seems like there is no force on the rotor, maybe more speed?

  • I can hear the the rotor at the back moving and that second hand is moving, but then it stops.

  • So we have this rigid rotor and it's rotating about the center mass.

  • The interaction between the two magnets caused the rotor to turn half a revolution.

    Academic text (2000)

  • As a result, the air exiting the other side of the rotor can be discharged into the atmosphere.

    Academic text (2000)

  • Reversing the current causes the rotor to rotate to its second position.

    Academic text (1995)

  • The rotor in the electric motor spins rapidly to generate energy as it rotates inside the stator.

  • The technician replaced the damaged rotor to restore the functionality of the generator.

Morphology

rotor = rotate (transparent) = rotate + or

The word is transparently built from 'rotate' plus '-or', referring to the rotating part of a machine.

Etymology

Rotor comes from the Latin root rot- (as in rotate) meaning 'to turn'. In a motor or generator the rotor is the part that spins inside the non-moving part called 'stator', and that turning is what makes or uses electrical energy.
