Abstract:
A fractional concentrated stator for use in electric aircraft motor includes an inner and outer cylindrical surface about an axis of rotation comprising different radii. The stator includes a plurality of teeth disposed on the inner cylindrical surface and extending radially inward, the cross-sectional area of each tooth increasing as it extends from the inner cylindrical surface. The stator includes a plurality of modular winding sets, each comprising at least a segment of electrically conductive material wound upon at least a tooth, an inverter providing electrical power to a configurable portion of the stator, and rotor shaft at the axis of rotation disposed coaxially within the stator. The rotor shaft further includes a cylindrical surface facing the inner cylindrical surface of the stator, a plurality of magnets coupled to rotor shaft and coupled to a propulsor and an air gap between the rotor and stator.
