The development of the superconducting magnetic levitation system for transport has been progressing in Japan since 1977. Now, a new test line (Yamanashi Maglev Test Line) has been completed in Yamanashi prefecture, and running tests started in April 1997.@We have succeeded in running tests of a maximum speed 550km/h. This system employs a linear synchronous motor (LSM) to drive vehicles. This paper describes the characteristics of LSM drive proved at its test line.
