Requirements for the industrial application of superconducting rotating electrical machines

The objective of the project reported in the paper is the design and constr uction of an experimental high Te (HTS) synchronous machine. The machine is excited with rare-earth permanent magnets on the rotor and rod-shaped arma ture conductors on the stator. The machine incorporates Bi-based HTS conduc tors supplied with electrical contacts. in the design procedure a special a ttention has been paid to the considerations regarding industrial applicati ons of HTS rotating electrical machines both in motor and generator modes o f operation. Possible applications have been analyzed to formulate the requ irements for the machine to be applied and calculations have been performed to check how the above requirements can be met by HTS machines. Comparison s have been made between conventional and HTS machines designed for particu lar practical cases..
