Summary on Grant Application Form
Losses in magnetic materials used in electrical machine cores consume 5 to 10 percent of all electrical power generated. Research carried out by the applicant has helped industry achieve significant but incremental improvements in material properties and utilisation which has had a marked impact on this figure. However, magnetisation conditions in materials used in a wide range of modern applications ranging from wind generation to electrical drives for hybrid vehicles, cause higher losses than in conventional machines and unless controlled may wipe out many of the benefits hoped for from alternative energy systems and novel machine designs. It is therefore essential to rethink our understanding of losses for industry to use to produce and utilise soft magnetic material in which these additional losses are minimised.The main aim of the research is to significantly improve our understanding of losses in soft magnetic materials and use results of a systematic series of experiments to develop methods of analysing and predicting losses under complex magnetisation conditions. The new awareness will be disseminated within industry to stimulate production and more effective use of materials which will be more efficient under such conditions. A new understanding of eddy current and hysteresis processes based on the research of the applicant and other internationally leading researchers will be acquired with the aid of studies of magnetic domain structures, Barkhausen noise and loss characteristics in electrical steels and compacted iron powder cores. The research would be carried out using unique world class magnetic characterisation systems developed by the applicant and his team under an EPSRC / OST JIF grant awarded for underpinning such research.The new analysis and knowledge will be used for specifying and demonstrating more appropriate methods of material characterisation and loss predictions vital for design and development of next generation high performance electrical machines.
