Title: Permanent magnet stator for miniature motor - has yoke and magnet sections which are located by injection moulding
Inventor: DRASCH JOSEF
IPC: H02K1/17
Filed: 1974-09-04
Abstract: The application is primarily to miniature motors for use in confined spaces, for example tape recorders or cine cameras. The segmental permanent magnet pole pieces are joined magnetically by two soft iron yoke sections. The mechanical stability of the structure is achieved by flattening the yoke sections in the space between the poles and filling this space by injecting a moulding material on either side of the yoke. This localised moulding is performed so that the diameter of the yoke back is not increased at any point. The moulding is mechanically improved by providing holes in the yoke between the poles through which the moulding material can penetrate.
