Magnetic fields of electrical operating components of electric-traction-motor powered vehicles, especially diesel electric and all-electric railway locomotives, are sensed as the vehicles pass given locations along their respective paths of travel, and the signals so obtained are processed to yield perceptible outputs, such as oscillograph charts or computer printouts, indicative of performance and any maintenance work that must be done for maximum utilization of available energy. In instances in which speed of the vehicle is a significant factor, that information is ascertained and utilized in the processing of the signals derived from sensing the magnetic fields. The apparatus comprises one or more magnetic field sensors, such as standard relay coils, strategically located with respect to the path of travel of the vehicle, and information processing equipment adapted to receive signals from the sensors and speed information, if significant, and to provide a perceptible output indicative of performance and any maintenance work required.
A method of determining performance characteristics of electric-traction-motor powered vehicles and electrical operating components thereof which produce magnetic fields during operation, comprising sensing the magnetic field of at least one of said electrical operating components from a stationary position outside of and not connected with the vehicle concerned as such vehicle passes said position, to thereby yield an electrical signal indicative of the magnetic field sensed;
A power propulsion system performance analyzer for vehicles having electric traction motors, comprising a pathway for vehicle travel;
