ABSTRACT:
An arrangement for increasing the normal force exerted by an electrically powered miniature vehicle on a track in order to improve the traction of the vehicle's wheels. Flux collectors used in association with permanent magnets mounted along the sides of the vehicle and forming part of the vehicle's electric motor exert an attractive magnetic force on power rails embedded in the track, which force substantially exceeds the force provided by the magnets alone. Each of the flux collectors is made of a sheet of material which is attracted by a magnet and is mounted adjacent to the magnet surface which faces away from the motor armature. Also, each of the flux collectors extends downward to a point in close proximity to one of the power rails and includes a flange extending along at least part of the lower surface of the permanent magnet against which it is mounted.
