Abstract
High temperature superconducting (HTS) maglev technology has been developed for more than two decades. Permanent magnet guideway (PMG) has been always used for the rail of a HTS maglev system so far. For the long distance HTS maglev system, PMG has some disadvantages in practice. In last few years, we carried out studies to investigate the feasibility of using electromagnetic guideway (EMG) for a HTS maglev system. EMG is not only more reliable, but also more controllable and flexible. We have proposed an E-shaped electromagnet that could be the basic element for building an EMG with good controllability and flexibility. The geometrical and circuitry design of the E-shaped electromagnet were first suggested through theoretical magnetic circuit analysis. The design then was examined and optimized by computer simulation. Afterward, we made a prototype and conducted several levitation tests to verify the design with a high precision measuring platform. In this article, the performances of the prototype with different exciting modes and different dimensions are reported and discussed.
