Welcome to this EEE power conversion research events
Background: Electric, hybrid, and turboelectric airplanes are currently being researched and developed to substantially reduce energy use and ultimately achieve zero carbon emissions. The presentation will cover specific electric motor technology and will review current trends and results available from major US programs funded by NASA and the Department of Energy (DOE), through the ARPA-E ASCEND framework. Special emphasis will be placed on the presenter’s research group novel concepts and research conducted under multiple NASA projects, including the ongoing large NASA ULI IZEA program with academic and industrial participation. Electric motor topologies, including PM synchronous in radial and axial flux configurations with Halbach arrays, coreless stators, special windings, superconducting and cryogenically cooled integrated systems will be reviewed in terms of ultra-high efficiency, power density, and reliability. The consequences of the largely different power specifications for the typical aircraft mission profiles, and the requirement for fault tolerance will be discussed together with the opportunities for using multiple and largely independent motor stages and modules, such as combinations of non-PM units with stator DC current stator excitation and reluctance rotors. The presentation will also include a proposed Markov chain-type technique to estimate reliability and a brief review of advancements in power electronics with muti-level converters, wide band gap (WBG) devices, electromechanical and thermal integration.
