Abstract
The invention relates to a circuit arrangement for use with a trackbound propulsion vehicle. The circuit arrangement includes a traveling-field winding which is installed alongside the vehicle roadbed and forms the stator of a linear synchronous motor whose exciter is disposed as a co-movable translator on the vehicle itself. More particularly, in order to be able to accelerate the propulsion vehicle with constant driving power, in accord with the invention, the traveling-field winding is designed such that the number of conductors per pole and phase thereof are inversely proportional to a pre-determined vehicle velocity.
