Abstract
A method for producing stator packs for long-stator linear motors of magnetic levitation vehicles is described. At first steel sheets are stacked to form a sheet stack, cross members are inserted into grooves of the sheet stack and the sheet stack and the cross members are connected with each other to form a solid structural unit. Further it is provided to so insert the structural unit into an open-top casting mold that the cross members are laid onto rims of the casting mold by means of head parts provided at their ends and are positioned by means of positioning pins provided at said ends. Afterwards the filling of the casting mold with a casting resin mixture takes place, advantageously pressureless, for the formation of a corrosion protection layer surrounding the sheet stack. After the hardening of the casting resin mixture the finished stator pack can be removed from the casting mold.
