the yoke in an unlocked position when the star is inserted into the yoke the star is rotatable to a locked position whereby the star is retained at the yoke via an interference fit application_number US 201414466099 A description referring now to the drawings and the illustrative embodiments depicted therein a stator of the present invention comprises a yoke and a star which are joined together and which rotate about a rotor fig1 5 and 6 the yoke and star are formed so that the star which may be laminated and comprise a plurality of layers of star elements may be readily inserted axially into the yoke which may be laminated and comprise a plurality of layers of yoke elements and then rotated relative to the yoke to provide a tight interference fit between the yoke and star the yoke and star elements and optionally the rotor too may be punched via a common punching process so that when the star and yoke are assembled together the interference fit between the components is tight and consistent the present invention designs the separation surfaces between the stator yoke and the separate teeth of the star so that they can be assembled after winding of the wire onto the star with a zero or near zero force needed for the axial movement of the star into the yoke and then with low force rotational locking since both the yoke and star are laminated in a plane perpendicular to the axial direction they produce a strong reaction force in axial direction while.
