Abstract: A method of manufacturing an electric motor wherein pole pieces, made of pole laminations provided with outwardly extending projections are assembled into pole piece blocks, which are provided with stator coils premounted thereon. The pole piece blocks are secured to a stator ring made of stator laminations. The projections on the pole pieces are inserted into depressions formed in an inner wall of the stator ring and are then anchored thereto by means of anchoring rods inserted axially through passages provided in the stator ring and holes formed in the projections of the pole pieces. The projections and the corresponding depressions mating therewith are shaped by the step of forming the stator laminations which are formed such that the spaces of the projections and depressions receiving the same in assembly will occur as a result of a selective laying together of pre-assembled lamination packs.

Abstract: An electric motor and a method of manufacturing the same, wherein pole pieces, made of pole laminations provided with outwardly extending projections and assembled into pole piece blocks, which are provided with stator coils premounted thereon, are secured to a stator ring made of stator laminations. The projections on the pole pieces are inserted into depressions formed in an inner wall of the stator ring and are then anchored thereto by means of anchoring rods inserted axially through passages provided in the stator ring and holes formed in the projections of the pole pieces. The projections and the corresponding depressions mating therewith are shaped by the stamping out of the stator laminations which are formed such that the shapes of the projections and depressions receiving the same in assembly will occur as a result of a selective laying together of pre-assembled lamination packs.
