(See quots.)
1657Cleveland Rustic Rampant Wks. 514 He was the Stator, the Saviour of the Nation.

[a. L. stator, agent-n. f. sta-, stāre to stand.]
1. Electr. The stationary portion of an electric generator or motor, esp. of an induction motor.
1895S. P. Thompson Polyphase Electr. Currents v. 113 In describing the parts of polyphase motors..[we] shall call the rotating part the rotor, and the stationary part the stator. 1902S. Sheldon & H. Mason Altern.-Current Machines 142 The stationary part of an induction motor is called the stator, and the moving part is called the rotor. 1903Nature 23 Apr. 588/2 The high pressure current is taken only to the stators of the high tension motors. 1903[see rotor 2].
2. The casing enclosing the revolving blades of a steam turbine. More widely, an immovable part of any turbine; spec. a stator blade (see sense 3 below), or a row of such blades.
1911Encycl. Brit. XXV. 846/1 The tips [of the blades] are fined down..so that in the event of contact taking place..between the ‘rotor’ or revolving part, and the ‘stator’ or case, they may grind without being stripped off. 1916J. W. M. Sothern Marine Steam Turbine (ed. 4) viii. 424 The turbine consists of two principal parts, the rotor or moving part, and the cylinder (sometimes called the ‘stator’) or stationary part. 1951Cohen & Rogers Gas Turbine Theory vi. 133 Each stage will consist of one rotating row followed by a stator but it is usual to provide an additional stator row at entry to guide the air correctly into the first rotor. 1962F. I. Ordway et al. Basic Astronautics x. 404 The rotor turns within the stator, which is a series of blades arranged in a circle around the inside wall of the compressor housing. 1967N. E. Borden Jet-Engine Fundamentals 80 The first four stages of the high-pressure compressor are provided with variable stators, automatically positioned by hydraulic actuators. 1971P. J. McMahon Aircraft Propulsion iv. 124 Figure 4.2 shows a view in the radial direction of the blading of a compressor stage—rotor plus stator—with the stators of the previous stage included for completeness.
3. attrib. and Comb., as stator coil, stator winding; stator blade, a small stationary aerofoil fixed to the casing of an axial-flow turbine, rows of which are positioned between the rows of rotor blades.
1946G. G. Smith Gas Turbine & Jet Propulsion (ed. 4) iv. 58 Stator blades to direct the air flow between stages will also be of either steel or light alloy. 1977J. L. Kerrebrock Aircraft Engines & Gas Turbines v. 120 There are normally three types of blade row in an axial compressor: the inlet guide vanes, the rotor blades, and the stator blades.
1904W. R. Bowker Dynamo, Motor & Switchboard Circuits 102 The ‘stator’ coils are arranged in a six-pole grouping.
1895S. P. Thompson Polyphase Electr. Currents v. 113 The stator winding is usually the primary, the rotor winding secondary. |
