ABSTRACT:
In winding the stator of a long stator linear motor without iron, the conductors of the traveling wave winding in the stator are designed as round jacketed lines which are fixed to a non-magnetic winding support by cross-bars and retained in place by hardenable non-magnetic material. The conductors of the traveling wave winding are approximately flush with the outside surface of the stator which is disposed opposite an exciter magnet on a moving vehicle.
