Original Abstract Submitted
an electrical machine includes a rotationally-fixed stator defining a rotational axis of the electrical machine and having a plurality of stator magnetic poles, the stator magnetic poles disposed about the rotational axis. the electrical machine also has a rotor rotatably mounted coaxially with the rotational axis and axially spaced from the stator, the rotor having a plurality of permanent magnets facing the stator magnetic poles. each stator magnetic pole includes a plurality of ferromagnetic laminations in a lamination stack that extends from a radially-inward extent to a radially-outward extent relative to the rotational axis, and a ferromagnetic composite pole portion affixed to the radially-outward extent or the radially-inward extent of the lamination stack of the stator magnetic pole.
