Efficiency maps for electric machines in electric vehicles. This project aims to improve methods for calculating and predicting efficiency maps, which describe how the efficiency of electric machines varies depending on their operating point. It will interpret and model their features, and link the design parameters to the resultant efficiency map. This project will consider machines including synchronous (permanent magnet, reluctance and wound-field) and induction types. Electric machines are n ....Efficiency maps for electric machines in electric vehicles. This project aims to improve methods for calculating and predicting efficiency maps, which describe how the efficiency of electric machines varies depending on their operating point. It will interpret and model their features, and link the design parameters to the resultant efficiency map. This project will consider machines including synchronous (permanent magnet, reluctance and wound-field) and induction types. Electric machines are normally designed for a single operating point, usually at rated torque and speed. The results are expected to improve machine design to give the best performance in typical driving conditions.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
A Novel Inline High-Efficiency Motor/Pump System. Around 19% of the world’s and 30% of the Australia’s electric energy is consumed by pump technologies. Significant energy savings are possible if the major components of pump systems, including inverter, motor and pump, operate at their maximum possible efficiency under varying loads. A novel pump design in this project accommodates integrated electronics in a submersible housing. A seal-less design helps mitigate several aspects of pump failure ....A Novel Inline High-Efficiency Motor/Pump System. Around 19% of the world’s and 30% of the Australia’s electric energy is consumed by pump technologies. Significant energy savings are possible if the major components of pump systems, including inverter, motor and pump, operate at their maximum possible efficiency under varying loads. A novel pump design in this project accommodates integrated electronics in a submersible housing. A seal-less design helps mitigate several aspects of pump failure and its in-line structure reduces assembly cost. Accurately measured efficiency maps will be utilised to demonstrate the non-linear relationship between motor and pump quantities as well as developing models for indirectly estimating feedback quantities and achieving the highest system efficiency.Read moreRead less
