Abstract
An arrangement for distributing electrical power to one or more portions of a linear motor stator, the stator being of the type which is disposed along a track for propelling a track-bound vehicle. Current is supplied to the stator from a line conductor which is supplied at both ends by respective power supplies. In a further embodiment which is useful for distributing electrical power to long stators, double-throw switching elements are connected to the power supplies for permitting the power supply to provide current to a selectable one of two adjoining line conductors.
Claims3
An arrangement for supplying electrical power to a first linear motor stator of the type used to propel a track-bound vehicle, the first linear motor stator being disposed along a track for producing a traveling-field which cooperates with an exciter disposed on the vehicle for propelling the vehicle along a first portion of the track, the first linear motor stator being connected by a first switching element to a first line conductor for receiving electrical current, characterized in that there are further provided
- first and second supply means connected at respective ends of the first line conductor, each such supply means providing a portion of an electrical current flowing through the first linear motor stator when the first switching element is in a closed state.
