Abstract: An electrical machine rotor includes a flux-conducting portion and a flux-inhibiting portion. The flux-conducting portion is conducive to conveying an electromagnetic flux and has a plurality of salient rotor poles and a portion of back material. The flux-inhibiting portion is less conducive to conveying an electromagnetic flux than the flux-conducting portion and is disposed entirely outside the boundaries of the rotor poles.

Abstract: An electric machine includes a stator assembly defining a longitudinal axis. The stator assembly includes a substantially cylindrical stator core that is concentric with and extends longitudinally along the longitudinal axis. The stator core includes a stator pole having an inner surface spaced radially outward from the longitudinal axis. The stator pole includes a first aperture extending radially outward from the inner surface of the stator pole. The electric machine also includes a rotor assembly rotatable about the longitudinal axis. The rotor assembly includes a rotatable shaft and a rotor core. The rotor core is concentric with and extends longitudinally along the longitudinal axis. The rotor core also includes a rotor pole including an outer surface spaced radially outward from the longitudinal axis. The outer surface is spaced radially inward from the stator pole inner surface.
