In the superconducting Maglev system, a method for providing on-board service power is one of the most important subjects of technological development. As a solution, a linear generator is being developed that can collect power without contact by utilizing the harmonic magnetic field of ground coils. It can also generate electromagnetic force between the superconducting magnets and ground coils by controlling the current in the generator coils. By using this controllable electromagnetic force, it becomes possible to add magnetic damping to the electrodynamic levitation system, which is characterized by an intrinsically very small damping force. This paper describes the results of the vehicle running tests of the linear generator using zero-phase current control, combined with a magnetic damping function.
