Abstract
An electric machine includes a stator and a rotor lamination assembly. The rotor lamination assembly may be configured and disposed relative to the stator. The rotor lamination assembly includes at least one lamination member wherein the lamination member defines at least magnet receiving aperture and a fastening region. The lamination member further includes a body disposed between an inner diametric edge and an outer diametric edge. The magnet receiving aperture includes a first end which extends to a second end such that the second end is spaced from the outer diametric edge to define a bridge region. The fastening region engages with a receiving region in a rotor shaft via an interference fit to generate a tensile load (or pre-load) in the body.
