LINEAR INDUCTION MOTOR ELECTRICAL BRAKING TEST

This report describes the electrical braking characteristics of a 2500-hp (at 250 mph) linear induction motor (LIM), which is used to propel and brake the LIM research vehicle. Three methods of electrical braking were investigated: ac dynamic braking, dc eddy current braking, and plugging. From the data acquired the following information was derived and is presented herein for each of the braking methods investigated: (1) LIM electrical braking characteristics in terms of braking force developed as a function of vehicle speed, with all data referred to a 2000-A primary current, (2) powerplant characteristics, (3) the location and magnitude of the braking energy dissipated, and (4) power and control equipment requirements. Pertinent LIM design information is also included to enable independent investigators to correlate analytical predictions with the test data published herein.
