A rotor includes a rotor core formed of webs defining a layout of the magnets in the rotor core. The rotor core has at least one layer of magnets forming a plurality of poles. Each pole includes a plurality of slots for holding a magnet, at least two ribs comprising web portions between the centerline slot and each wing slot, and a plurality of magnets arranged in corresponding slots. The slots have at least a centerline slot and two angled wing slots extending from a position at or around respective ends of the centerline slot towards an outer circumference of the rotor core. The wing slots may taper from a position at or around respective ends of the centerline slot towards an outer circumference of the rotor core.
