machine that converts electrical energy into mechanical energy. When an electric current is passed through a wire loop that is in a magnetic field, the loop will rotate and the rotating motion is transmitted to a shaft, providing useful mechanical work.

Stator

 

(1) In reaction turbines, a grating installed ahead of the runner of a hydraulic turbine; it usually consists of rotatable profile blades. The rotatable blades make possible adjustment of the flow of water through the turbine. Such adjustments are necessary to produce an optimum direction of the water stream at the vanes of the runner and thus to improve the efficiency of the turbine under abnormal operating conditions.

(2) In vane pumps, the stator consists of stationary vanes and is located behind the impeller (with respect to the direction of flow) in such a way as to provide the most favorable (axial) outflow of the fluid.


Stator

 

in electric machinery, the stationary part of a machine that serves as both a magnetic circuit and a supporting member.

A stator consists of a core and a frame. The core is made up of sheets of electrical steel; the sheets, which are 0.35–0.5 mm thick and insulated with varnish, are formed into stacks and fastened in the cast or welded frame. Stator windings fit into slots made in the core. To avoid substantial eddy currents and associated losses, the conductor of the stator winding is made up of several strands electrically in parallel. In high-power machines, these strands are braided (transposed). In linear motors, the core of the stator is unrolled into a line.
