Abstract
A rotor for an electric machine includes a core comprised of stacked laminations that define pockets between a hub portion and a pole portion. Each of the pockets are configured to receive magnetic material and define center cavities between regions of magnetic material to eliminate a flux leakage path between the magnetic materials. A cured mixture including an epoxy and a magnetic powder is disposed within the center cavities. The magnetic material may include sintered magnets and a cured mixture.
