ABSTRACT:
The invention relates to a linear motor feeder system in which a linear motor is supplied with driving power from equipment on the ground. Divided armature coils are serially connected two by two to form sets of the armature coils, the junction between the two armature coils in each set is connected to one feeder and both ends of the set of armature coils are connected to two feeders via respective switches, and short-circuiting switches are connected between mutually adjacent ones of the feeders. By turning these switches ON and OFF in accordance with the position of a vehicle, the linear motor is driven by a single frequency converter connected across feeders which are in turn connected across both ends of the divided armature coils.
