We have been jointly developing an on-board electric power source for MAGLEV trains by applying a 30kW generator for gas turbine hybrid passenger cars.

Operating the generator on a test model apparatus simulating the generator installed in a MAGLEV train, we investigated its electrical and mechanical characteristics with the location close to superconducting coils. The effects of magnetic field on the generator’s characteristics are investigated and described in this paper.

MAGLEV trains require about a 50kW on-board power supply per car. At present, we are designing a 50kW gas turbine generator on the basis of the 30kW gas turbine generator.
