Abstract:
A rotor of an electric machine includes a rotor core having a plurality of axially-stacked rotor laminations, and a plurality of permanent magnets. The plurality of permanent magnets are first permanent magnets secured at the core outer circumferential surface of the rotor core and are made of a first permanent magnet material with a first magnetic orientation. The plurality of permanent magnets are secured to the rotor core via a plurality of mechanical interface joints defined by at least one first mechanical interface feature having a permanent magnet channel with a magnet channel surface, located inside the permanent magnet and at least one second mechanical interface feature having a core channel with a core channel surface located inside of the rotor core. At least one complimentary mechanical interface member is inserted in the magnet channel and the core channel, having surfaces complimentary to the magnet channel and the core channel.

Claim (Index 12):
An electric machine comprising:\n a stator; a rotor located about a rotor axis, defining an air gap between the rotor and the stator, the rotor magnetically interactive with the stator and including:\n a rotor core, wherein the rotor core comprises a plurality of axially-stacked rotor laminations; and \n a plurality of permanent magnets, each of the plurality of permanent magnets having a magnet inner circumferential surface, a magnet outer circumferential surface, and two opposing radial side surfaces, the plurality of permanent magnets secured at the core outer circumferential surface of the rotor core, the permanent magnets are first permanent magnets made of a first permanent magnet material with a first magnetic orientation; \n wherein the plurality of permanent magnets are secured to the rotor core via a plurality of mechanical interface joints, the plurality of mechanical interface joints defined by:\n at least one first mechanical interface feature having a permanent magnet channel with a magnet channel surface, disposed inside the permanent magnet, with the tangent of the magnet channel surface defined by an angle that is between zero and 90 degrees with respect to the magnet inner circumferential surface; \n at least one second mechanical interface feature having a core channel with a core channel surface disposed inside of the rotor core, with the tangent of the core channel surface defined by an angle that is between zero and 90 degrees with respect to the core outer circumferential surface; and \n at least one complimentary mechanical interface member inserted in the magnet channel and the core channel, having surfaces complimentary to the magnet channel and the core channel; \n \n wherein the permanent magnets secured to the rotor core are separated by a fixed angle or a fixed distance; and wherein the side surfaces of the first permanent magnets are in contact with air, a non-magnetic and non-electrical conducting material, or a second permanent magnet.
