NASA is researching electric aircraft and conducted research on key components like axial flux motors and an electric compressor. The axial flux motor utilizes a "halbach array" configuration of magnets to increase efficiency. It can be stacked axially, taking up less frontal space ideal for aerospace. Researchers integrated the motor into a compressor hub. Prototypes were created using additive manufacturing with composite materials, allowing faster testing of concepts. NASA sees promise in this electric aircraft technology and is continuing research.
