Wind energy installation has a ring generator with a stator having grooves spaced at intervals on an internal or external periphery for receiving a stator winding.

摘要

A stator (10) with an inner rotor has grooves (12) on an inner periphery running in an axial direction. The stator is held in a holding device (14) set on a base so as to keep the stator and the grooves at a level that forms a favorable working position. Since the stator forms part of a ring generator and has a diameter of several meters and correspondingly great weight, the stator runs on rotary bearings (16) and turns so as to bring the operating grooves into a desired position. Independent claims are also included for a device for producing a stator for a synchronous machine and for a synchronous machine with a rotor and a stator.
