High-temperature superconducting motors and generators for power grid applications

J.W. Bray     GE Global Research, Niskayuna, NY, USA


This chapter describes the motivations for and benefits of superconducting motors and generators and explores the reasons why they are not yet commercialized. The design and construction principles of these machines are outlined with emphasis on those actions required by the use of superconductivity. The possible types of superconducting motors and generators are discussed, and the notable larger prototypes of these machines that have been built are summarized. These machines place significant requirements on superconducting wire and necessitate new cryogenic subsystems, and the consequences are explained. ...
