rotors

Helicopter lifting components

Rotors is the plural of rotor—a rotating component in a machine.

Helicopter rotors are the spinning blades that provide lift.

In a car's braking system, rotors are the metal discs that brake pads clamp against to slow the wheels: The mechanic said I need new rotors.

Electric motors and generators have rotors that spin within stationary housings.
