| Summary: | The growing momentum in the aircraft industry toward the idea of a hybrid electric-powered or more electric aircraft (MEA), and eventually an all-electric aircraft, exemplifies the industry's efforts to improve aircraft performance, lower operating and maintenance costs, boost dispatch reliability, and lower gas emissions. The MEA idea, in particular, calls for the use of electricity for all non-propulsive devices. Traditionally, various auxiliary power sources, including hydraulic, pneumatic, mechanical, and electrical, are used to drive these non-propulsive devices. These motors must have a wide range of operating speeds in addition to high efficiency, compactness, and torque density properties. Without the employment of rare-earth permanent magnets, these requirements have not yet been met. This paper demonstrated that it is possible to create a switched reluctance motor that is competitive with rare-earth permanent-magnet motors. Experiments revealed that the designed motor outperforms ordinary rare-earth permanent-magnet motors in terms of efficiency, torque density, and range of working speeds. |
