This report describes the electrical performance characteristics of a 2500-hp (at 250 mph) linear induction motor (LIM), based on data acquired while propelling the LIM research vehicle over a 0-to-250-mph speed range. Pertinent LIM design information is included to enable independent investigators to correlate their mathematical models with the test data published herein. The principal end product of this effort is tabulated LIM performance, in terms of thrust, voltage, power factor, efficiency, input and output power, velocity, and percent slip at five excitation frequencies and at 1-Hz slip frequency increments, with all data referred to a 2000-A primary current. From the acquired data the following information was derived and included in this report: LIM performance characteristics (thrust vs slip at constant current, power fctor vs slip, and efficiency vs slip), voltage- and current-source presentation of LIM data, influence of LIM end effects, and other LIM data, relevant to future design activities.
