Abstract
An electrical propulsor motor includes a stator having a hollow cylinder with an inner cylindrical surface and an outer cylindrical surface, rotor incorporated in a hub of a propulsor and mounted to the stator, including a first cylindrical surface facing the inner cylindrical surface, where the inner cylindrical surface and first cylindrical surface form a first air gap, a second cylindrical surface facing the outer cylindrical surface, wherein the outer cylindrical surface and the second cylindrical surface form a second air gap, and a plurality of axial impeller vanes mounted to at least one of the first cylindrical surface and the second cylindrical surface and within at least one of the first air gap and the second air gap and positioned to force air through the at least one of the first air gap and the second air gap when the rotor rotates about the axis of rotation.
