LIM RESEARCH VEHICLE REACTION RAIL CURRENT DISTRIBUTION TESTS

A linear induction motor (LIM) operates, in principle, in the same manner as a conventional rotating induction motor. But LIM performance is subject to degration by so-called end effects, particularly at relatively high vehicle speeds (100 mph upwards). End effects are the phenomena caused by rapid generation of currents in the reaction rail at the entrance end of the LIM and their equally rapid decay at the exit end. Specific knowledge of dynamic current distribution and directional characteristics will materially aid the future design of improved LIMs. This report documents an investigation of current distribution in the LIM research vehicle (LIMRV) reaction rail at the U.S. Department of Transportation High-Speed Ground Test Center, Pueblo, Colorado.
