The '''stator''' is the stationary part of a rotary system,<ref name="Klempner">{{cite book |last1=Klempner |first1=Geoff |last2=Kerszenbaum |first2=Isidor |title=Operation and Maintenance of Large Turbo-Generators |date=2004 |publisher=John Wiley & Sons |isbn=978-0-471-61447-0 |url=https://books.google.com/books?id=DPdkLp_crLAC&dq=stator&pg=PA34 |language=en}}</ref> found in [[electric generator]]s, [[electric motor]]s, [[Siren (alarm)|sirens]], [[mud motor]]s, or biological rotors (such as bacterial [[Flagellum|flagella]] or [[ATP synthase]]). Energy flows through a stator to or from the rotating component of the system, the [[Rotor (electric)|rotor]]. In an electric motor, the stator provides a [[magnetic field]] that drives the rotating [[Armature (electrical)|armature]]; in a [[Electric generator|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.
