An important thrust in current aerospace research is aircraft electrification, including propulsion system electrification. For an electrified propulsion system to provide net benefit over conventional propulsion, the electrical systems must meet high specific power, power density, and efficiency standards. This thesis presents experimental validation of components of a megawatt scale permanent magnet synchronous motor targeting power density of 13 kW/kg and 96% efficiency. This experimental validation demonstrates that it is possible to build a stator appropriate for this application. The results closely match the FEA analysis and increase confidence that the final motor will be capable of meeting the design requirements. The results also highlight the importance of tight manufacturing tolerances to minimize circulating currents and associated losses. In addition, this thesis describes work on testbed development. Specifically, the thesis discusses how to determine effective winding and resistor combinations to allow for testing the machine as a generator across a wide range of operating conditions with limited components.","abstract_html":"This thesis presents work evaluating the performance of components of a novel high-specific-power permanent magnet synchronous machine (PMSM) for electric aircraft propulsion.
