Process, general design parameters and first test results of our high temperature superconductingĭesign and test of superconducting magnet (SM) for a superconducting synchronous generator (SSG) are studied in this paper. Generation of homopolar electromagnetic turbines. Generator concepts over the last few years and has combined its experience to develop a new Guina Energy Technologies has developed, built and tested different motor and Only DC electric and magnetic fields and have no AC losses in the coils or the supporting Homopolar machines are pure DC devices that utilise Both technologies are critical toĬonstructing high performance machines. Surrounded by a conforming stationary channel of the stator. Liquid metal layer that fills a circular channel formed by the moving edge of a rotor and Liquid metal currentĬollectors deliver a low resistance, stable and low maintenance sliding contact by using a thin Of additional shielding coils reduces weight and stray field of the system. Static drive field as well as effective shielding for the field critical sliding contacts. The unique arrangement of the superconducting coils delivers a high In this paper we present our unique approach to high power and high torque homopolarĮlectromagnetic turbines using specially designed high field superconducting magnets and liquid Pure DC operation, high power-to-weight ratio and that rotating magnets or coils are not Some of the advantages of these machines are ripple free constant torque, Recent developments in superconducting, cryogenic and slidingĬontact technology together with new areas of application have led to a renewed interest in Homopolar machines were the first continuously running electromechanical converters everĭemonstrated but engineering challenges and the rapid development of AC technology prevented
