Abstract: The present disclosure provides rotating impeller systems comprising a shaft with a plurality of blades attached to its inner wall. In motor applications, the shaft serves as the electrical and mechanical elements of a pump or vacuum system. In particular, the shaft rotates when energized, and the attached blades create a driving force. The rotating impeller systems of the present disclosure may be used in generator applications, where the shaft serves as the rotor and a housing serves as the stator. Generator applications include wind energy or hydroelectricity.
