Armature’s reaction in synchronous devices with smooth magnetic gap

Abstract

The paperwork illustrates a synchronous generator with permanent magnets where the winding is mounted directly on the interior side of the no slotted armature, which simplifies the design technology for this type of generator. It is proved that the armature’s reaction is six times reduced, approximately, the toothing harmonics are removed and the external feature is a lot more rigid as compared to the classical generator.
