Abstract
For the magnetically levitated (Maglev) transport system that uses superconducting magnets (SCM), it was important to develop an onboard power source that does not require contact with the ground and minimizes emissions of environmental pollutants such as noise and exhaust gases. We studied the feasibility of a linear generator (LG) that is integrated into an existing SCM, improved the output, power factor and measuring system, and tested it on the Yamanashi Maglev Test Line. A linear generator installed on the left half of a bogie was able to supply 25 kW of power to a Maglev vehicle in the 400 km/h to 500 km/h speed range, there being a good correlation between the results of analysis and vehicle running test measurements. The linear generator system thus expected to be of practical use.
