Stator

Monday, January 28, 2013

A stator is the part of an electric motor, generator, or turbine, which remains fixed with respect to a rotating part called rotor. In a motor and generator, it has insulated copper wire coils, which generate a magnetic field. A stator is composed of a core and a frame. The core consists of thin sheets of steel joined together tightly by insulating varnish, forming into stacks and fastened in the cast or welded frame, which is round. Stator copper wire windings fit into slots made in the core.
