Rotor \Ro"tor\, n. (Elec.) The rotating part of a generator or motor. Contrasted with stator, the stationary part.

Douglas Harper's Etymology Dictionary

1873, irregular shortening of rotator (see rotate (v.)), originally in mathematics. Mechanical sense is attested from 1903; specifically of helicopters from 1930.


n. A rotating part of a mechanical device, for example in an electric motor, generator, alternator or pump.

  1. n. the rotating armature of a motor or generator [syn: rotor coil] [ant: stator]

  2. the revolving bar of a distributor

  3. rotating mechanism consisting of an assembly of rotating airfoils; horizontal rotors on a helicopter or compressor rotors of a jet engine


ROTOR was a huge and elaborate air defence radar system built by the British Government in the early 1950s to counter possible attack by Soviet bombers. The system was built up primarily of war-era radar systems, and was used only briefly before being replaced by the more modern Linesman/Mediator system. A similar expedient system in the United States was the Lashup Radar Network.

Rotor (ride)

The Rotor is an amusement park ride, designed by German engineer Ernst Hoffmeister in the late 1940s. The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe during the 1950s and 1960s. The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron.

Rotor (electric)

The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.

Rotor (mathematics)

A rotor is an object in geometric algebra (or more generally Clifford algebra) that rotates any blade or general multivector about the origin. They are normally motivated by considering an even number of reflections, which generate rotations (see also the Cartan–Dieudonné theorem).

The term originated with William Kingdon Clifford, in showing that the quaternion algebra is just a special case of Hermann Grassmann's "theory of extension" (Ausdehnungslehre). Hestenes defined a rotor to be any element R of a geometric algebra that can be written as the product of an even number of unit vectors and satisfies R = 1, where is the "reverse" of R—that is, the product of the same vectors, but in reverse order.

Usage examples of "rotor".

The rotor wash whipped at Abies as the helicopter turned above, then dipped sharply down behind the tree cover and disappeared.

And the aileron and rudder controls, and those which governed the pitch and tune of the rotor blades, by whose combined means the little gig could have been brought down to the surface, were out of operation.

Friday, November 4 2244 hours Landing zone in hills Near Chah Bahar, Iran Murdock watched as Magic and Kat both ran to the open door of the Seahawk while the rotors whirled.

The Blackhawk lifted off in a clatter of rotors, tilted forward, and then buzzed over the field, straining for altitude across the face of Howell Mountain, accompanied by the Cobra.

Every time I made a circuit I saw the green hillside behind the cenote coming closer until it was too damned close altogether and I thought the blades of the rotor were going to chop into projecting branches.

Down the flight deck below, the jet turbines of twelve Harbin Z-9A helicopters began to spool up, reaching full power a few moments later, the main rotors of the big machines beginning to spin, beating the rainy air of the storm-darkened dusk.

I killed the engine, hit the belt release and was out of the heli in seconds, ducking under the rotors as they wound down.

The heli lifted a little and as the rotors began to take the weight, I glanced behind me into the cab.

Grateful for the relative silence of the pounding rotor blades, Nunzio Spumoni escorted the Don to the former first lady and ex-wife of Willie Mandobar.

He lifted the collective lever on his left side, checking the tachometer to ensure that the automatic throttle was compensating for the drag of the increased rotor pitch.

All that yakking was like slow gunfire, and the drafts from the rotor blades made gusts of grit flicker at the windows.

The deck trembled slightly as the ship accelerated, the reactor circulation pumps aft--huge pumps, each the size of a compact car--started up, their 1500 horsepower motors spinning the rotors, pumping the coolant water through the core so the reactor power could double from 50 to 100 percent.

It was the governor, that comfortingly stable rotor at which he always looked after too long a time spent staring at the precessing gyroscopes.

He could imagine those shining rotors starting to turn, spinning faster and faster, spinning, precessing at right angles to all the dimensions of normal space, tumbling through the dark infinities, dragging the ship and all aboard her with them as the temporal precession field built up.

When we would hover down into a resupply and pull out medevacs, our crews would literally clear the tail room down a little tiny slot and we would have to sometimes chop away pieces of tree with the rotor blades.
