Abstract: A system for supplying electric power to and automatically controlling the speed of driverless, electrically driven, wheeled vehicles on a guide way. The system includes a power distributing track divided into a plurality of power segments and a plurality of electrical power sources each cyclically operated at different frequencies coupled to different predetermined power segments of the track to create a series of travelling waves, each at a different frequency, in the segmented track. A vehicle including an AC induction driving motor coupled to one power segment of the track receives electrical energy at the particular frequency appearing at a particular moment at a particular power segment. The induction motor in the vehicle continues to receive that particular frequency and, hence, maintain a constant torque so long as the vehicle continues to travel along the track at the desired rate of speed. Should the speed of the vehicle exceed or drop below the desired rate of speed, the induction motor will receive a preceding or succeeding travelling wave of such frequency as to compensate for the increase or decrease in speed thereby causing the induction motor to maintain the desired vehicle speed along the track.
