In the superconducting Maglev system, it is important to develop a non-contact on-board power source that does not generate environmental pollution such as noise and exhaust gas. We have studied a combined superconducting coil (SC) type linear generator, which, we believe is the most realistic system. The linear generator system has increased output, and improved power factor and measuring equipment.
  In this paper, the linear generator system is experimented in running tests on the Yamanashi Test line. We can supply power of 25kW to half a car in the speed range 400km/h to 500km/h. A good correlation is recognized between analysis and measurement in the running tests. This linear generator system is expected to be applicable to practical use.
