Abstract:
An electric machine comprising:a rotor with a shaft having electromagnetic material portions therein, the rotor arranged to rotate freely about the central axis; and a stator including: a cylindrical body portion having a central major axis, the stator, and rotor arranged such that their major central axes are aligned with one another; a magnetic core, having a center axis aligned with that of the stator the magnetic core having a plurality of axially arranged slots formed therein; a plurality of conductive blades arranged axially about the center axis of the stator, the conductive blades formed of a rigid conductive material, each conductive blade being disposed within a respective one of the slots formed in the magnetic core, and the conductive blades carrying electric current flow such that the conductive blades serve as windings for the machine; and a common planar interconnect structure, disposed at one end of blades, to provide electrical interconnections for current flow through the blades in a desired number of turns and phases and to support the conductive blades within their respective slots without mechanically contacting the core.
