Wide Speed Range, Inverterless, Constant Current Mode Alternator. Increasing auxiliary electric power demands in cars due to proposed new features such as electromechanical valves and active suspension has created a pressing need for a higher power car alternator.

Increasing auxiliary electric power demands in cars due to proposed new features such as electromechanical valves and active suspension has created a pressing need for a higher power car alternator. There has also been a continuing need for improved alternators for small-scale renewable energy generation such as wind turbines. These applications require the lowest possible cost solution which meets the challenging technical specifications. Present research in this area is focussed on expensive inverter-based methods. We propose a low-cost, "inverterless" alternator configuration based on a specially-designed interior permanent magnet machine operating in a new current source mode.Read moreRead less
Advanced Future Automotive Electrical Machines based on Amorphous Iron. Electric machines consume about 70% of all electrical energy generated. Electric machines constructed from a promising magnetic material called amorphous iron can be much more efficient than conventional designs, hence saving energy. Amorphous iron is normally difficult to cut accurately into the shapes required in electric machines. We propose to design and construct high-efficiency permanent magnet machines based on amorp ....Advanced Future Automotive Electrical Machines based on Amorphous Iron. Electric machines consume about 70% of all electrical energy generated. Electric machines constructed from a promising magnetic material called amorphous iron can be much more efficient than conventional designs, hence saving energy. Amorphous iron is normally difficult to cut accurately into the shapes required in electric machines. We propose to design and construct high-efficiency permanent magnet machines based on amorphous iron for automotive applications, which will be cut using an innovative Australian waterjet cutting technique. The key challenges are to optimise the machine design for commercial production given the capabilities and limitations of the material and the new cutting process.Read moreRead less
