Noun

rotor (plural rotors)

1. A rotating part of a mechanical device, for example in an electric motor, generator, alternator or pump.
   • 2013 July-August, Lee S. Langston, “The Adaptable Gas Turbine”, in American Scientist:

     Turbines have been around for a long time—windmills and water wheels are early examples. The name comes from the Latin turbo, meaning vortex, and thus the defining property of a turbine is that a fluid or gas turns the blades of a rotor, which is attached to a shaft that can perform useful work.

2. The wing of a helicopter or similar aircraft.
3. A quantity having magnitude, direction, and position.
