Title:
電気機械に用いられるメインエレメント
Document Type and Number:
Japanese Patent JP2007526737
Kind Code:
A
Abstract:
A primary element for an electrical machine has a magnetically conductive body including a lamination stack with a plurality of axially extending teeth disposed in a star pattern, and a winding of annular coils wound separately as coil-body-less air coils and mounted radially onto the teeth. To attain an axially and radially play-free seat of the annular coils on the teeth, on each face end of the magnetically conductive body, one compensation element, which is elastically deformable in the axial direction of the tooth, is placed on each of the face ends, located in a transverse plane to the body axis, of the teeth, onto which compensation element the annular coil slipped onto the tooth is pressed axially. All the compensation elements on one face end are joined together via a closed ring element to make a one-piece compensation mask of insulating plastic.
