Abstract:

Current Permanent Magnet (PM) machinery designs, used in hybrid electric vehicles (HEVs) and plug-in hybrids (PHEVs), suffer from increased eddy current losses in newer applications with higher operating speeds and/or higher pole count. The resistivity of the flux-carrying materials and the design of the machine impact the character of the losses (magnitude and localization). At partial power conditions, where core losses are high but net power output is low, the net impact on efficiency can be more pronounced. This project will employ commercially available finite element analysis (FEA) models to predict eddy current rotor losses for both interior PM and surface PM machine models. The models will be substantiated and improved upon through experimental testing of PM prototype machines. Commercial Applications and other Benefits as described by the awardee: In addition to advanced vehicle applications, the technology should find use in industrial applications related to compressors, conveyors, machine tools. Likewise, the results should be advantageous for aerospace and military applications, particularly all-electric ship and all-electric aircraft programs
