Abstract
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.
