Abstract
A rotor comprises a first rotor lamination and a second rotor lamination. The first rotor lamination and the second rotor lamination are configured for defining, when joined into rotor assembly, a central axis of rotation and a plurality of interior magnet pockets disposed symmetrically about the central axis of rotation, each pocket of the plurality of interior magnet pockets is configured for housing and retaining a permanent magnet. A method of forming a rotor comprises forming a first rotor lamination and a second rotor lamination, rotating the second rotor lamination about an axis of symmetry of the second rotor lamination; and mating the first rotor lamination to the second rotor lamination such that a first notch of the first rotor lamination is disposed adjacent to the first notch of the second rotor lamination.
