Patent ID: 7370402

Claim:
A method for producing stator packs ( 1 ) for long-stator linear motors of magnetic levitation railways, comprising of the following method steps: Stacking a plurality of punched ferromagnetic sheets ( 3 ) coated with an adhesive to form a stack ( 2 ) that is provided with continuous grooves ( 4 ) in one surface; Inserting a cross member ( 6 ) each into each groove ( 4 ), each cross member ( 6 ) having at both ends a head part ( 7 ) protruding beyond said metal sheet stack ( 2 ) projecting from said groove ( 4 ) and provided with a recess ( 11 ) towards its underside, with at least one passage ( 8 ) each being configured in each head part; Connecting the metal sheet stack ( 2 ) and the cross members ( 6 ) to a firm structural unit; Inserting the structural unit into an open-top cavity ( 159 ) of a casting mould ( 12 ) in such a manner that the metal sheet stack ( 2 ) comes to rest in the cavity ( 15 ) and that the cross member ( 6 ) with its head parts ( 7 ) lays itself onto rims of wall sections bordering the cavity ( 15 ), wherein positioning pins ( 19 ) provided at the wall sections at least partly enter into the passages ( 8 ) of the head parts ( 7 ) and wherein the arrangement is so chosen that spaces remain between the walls bordering the cavity ( 15 ) and the bottoms of the casting mould ( 12 ) on the one hand and the metal sheet stack ( 2 ) and an adjacent part of the cross members ( 6 ) being arranged in the grooves ( 4 ) on the other hand; Filling the cavity ( 15 ) with a casting resin mixture ( 22 ) to cover the metal sheet stack ( 2 ) and the adjacent parts of the cross members ( 6 ) with a corrosion protection layer; Opening the casting mould ( 12 ) after an at least partly hardening of the casting resin mixture ( 22 ), and Removing the stator pack ( 1 ) from the casting mould ( 12 ).
