Title: Magnetic induction supported train - with track loops joined at equipotential points to form differential coils for lateral stability
Inventor: LICHTENBERG ALFRED DIPL ING
IPC: B60L13/00
Filed: 1976-02-23
Abstract: The hovertrain is supported on a magnetic induced field and is propelled by linear induction. Superconducting coils (1, 2) under the train generate the lift by interaction with the track coils. The track coils are arranged in a pattern (4, 5) to provide the travelling field for linear induction. Joining links (7) are provided at equipotential points so that the induced current from the train coils (1, 2) can flow in opposing direction in each side of the track for automatic lateral steering control. Only one set of track coils are thus required, with the coupling links enabling the track coils to perform a dual purpose.
