Abstract: An interior permanent magnet electric machine includes a stator having a plurality of teeth disposed around a circumference oriented radially towards a center defining slots interposed between each of the teeth, and a conductive winding wrapped around at least one of the teeth of the stator to receive an electrical current. The electric machine also includes a rotor which is rotatable relative to the stator. The rotor defines a plurality of openings configured to hold permanent magnets near an outer portion of the rotor and a number of spokes interposed between mass reduction cutouts located closer to a center of the rotor relative to the permanent magnets. Each of the permanent magnets defines a magnetic pole and each of the spokes is circumferentially aligned with one of the magnetic poles.

Abstract: An electric machine is provided that includes a rotor assembly having a rotor core configured to support permanent magnets spaced around the rotor core to define a number of rotor poles. The rotor core has multiple rotor slots arranged as multiple barrier layers at each of the rotor poles. The rotor core is configured so that the electric machine satisfies predetermined operating parameters. In one embodiment, the electric machine is coupled with an engine through a belt drive train and provides cranking (engine starting), regeneration and torque assist modes.

Abstract: The disclosure may generally relate to a motor which may include a rotor core which may include a first rotor lamination portion and a second rotor lamination portion. At least one magnet may be operably coupled to the first rotor lamination. The first rotor lamination may be in contact with the at least one magnet and the second rotor lamination may not be in contact with the at least one magnet. Additionally, the first rotor lamination and the second rotor lamination may be comprised of different materials.
