Abstract
The invention relates to a stator packet for a long stator linear motor of a magnetic levitation train. The stator packet is composed of a plurality of sheet metal layers (6) comprising alternating grooves (7) and teeth (8) for receiving alternating-current windings (20). The grooves (7) are configured so that the windings (20) can be pressed into the same and retained therein without additional auxiliary means. According to the invention, the grooves (7) and teeth (8) are congruent, have centrally symmetrical side walls (12, 14), and are coated only with a thin corrosion protection coating that changes the shape of the teeth and grooves only insignificantly.
