Design and Performance Evaluation of a Tubular Linear Switched Reluctance Generator with Low Cost and High Thrust Density

This paper presents the design and performance evaluation of a tubular linear switch reluctance generator (TLSRG) with ferromagnetic rings to a conventional teeth-type TLSRG. The referred ferromagnetic rings are magnetically isolated with each other thus eliminate the stator yoke and make better utilization of material. Since only one set of ring windings are housed in the translator, no electric insulation measures are required. A standard analytical design procedure is developed for the presented generator and two demonstrators with identical dimensions are designed. The performance characteristic of the two generators are obtained and compared to each other in terms of inductance, load force, output current, and power density. The results demonstrate that the presented generator is superior to the teeth-type generator as linear generation systems such as electromagnetic dumper and wave energy conversion.
