Characteristic Analysis of HTS Linear Synchronous Generators Designed With HTS Bulks and Tapes

Two types of high temperature superconducting (HTS) linear synchronous generators (LSG) have been analyzed, which models developed have either an HTS bulk magnet array or an HTS tape coil as their secondary mover. The no-load induced voltage and output power characteristics versus the trapped flux density of the HTS bulk magnets, the HTS tape coils´ excitation currents, the secondary mover speed and the air gap length have been obtained using the Finite-Element Analysis (FEA). The principal characteristics of the HTSLSG with the secondary made by the HTS materials have been identified. The HTSLSG model under sinusoidal driving mode has been simulated, and also the electromagnetic force on the HTS secondary. The characteristic analysis provides a base for practical development of an applicable HTSLSG.
