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.
Claims12
A linear motor stator adapted to be disposed on a track and to cooperate with a vehicle containing an excitation winding comprising:
- (a) a form for the stator for defining a space having a preselected cross-sectional configuration suitable for placement on a track roadbed;
- (b) a plurality of electrically conductive lines, each such line having at least one electrically conductive element surrounded by an insulating jacket;
- (c) non-magnetic retention means in said form for fixing each of said lines individually within said space defined by said form in a position which produces a substantially flat traveling wave stator winding, portions of each of said lines being disposed adjacent and parallel to a surface plane of said form;
- and
- (d) a non-magnetic material which is poured while in a fluid state into said form so as to occupy the remaining space defined therein, and which hardens to further fix said lines in said position fixed by said retention means.
