The SERAPHIM linear induction motor consists of air-core, discretely-energized coil capable of efficiently providing high thrust at low and high speed. With the potential for a low-cost guideway by the use of a wide clearance between active vehicle coils and passive track coils, this propulsion system is being evaluated for applications in low-speed urban maglev transit. A concept four-coil motor has been developed to meet the requirements of an urban transit route that could include a mountainous section based on information from the Low-Speed Maglev Technology Development Program and the Colorado Department of Transportation I-70 Mountain Programmatic Environmental Impact Study. The concept includes definition f the track coils, power supply, and cooling systems. Thrust and efficiency curves are calculated using an improved motor-circuit-analysis code using normal and high-temperature superconductors (HTS). The design of a half-scale motor coil to operate at stress levels necessary to meet urban transit applications is presented that includes electrical, thermal, and mechanical stress analysis. Fabrication of coils and power supply is in progress for evaluation in a static test stand that also includes cooling, diagnostics, controls, and support structure. Test plans for the coil evaluation are discussed.
