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.

Miniature vehicle with magnetic enhancement of traction

A miniature electrically powered vehicle including an electric motor having a pair of permanent magnets mounted in the car to serve as the stator of the motor and also being mounted to extend in close magnetic proximity to the electric rails positioned in the track upon which the vehicle is operated. The magnets are mounted one behind the other in the vehicle such that a magnetic flux path exists running between one of the permanent magnets to at least one of the electric rails and then to the other of said permanent magnets. The resulting magnetic force between the car and the track provides an increased normal force of the car against the track to increase the traction of the driving wheels and to decrease slippage and prevent the vehicle from spinning as it negotiates curves in the track.
