Stator

This article is about a component of electromotive devices. For the component of a compressor, see Axial compressor. For the genus of beetles, see Stator (beetle).

The stator is the stationary part of a rotary system,[1] found in electric generators, electric motors, sirens, mud motors, or biological rotors (such as bacterial flagella or ATP synthase). Energy flows through a stator to or from the rotating component of the system, the rotor. In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.
