摘要： A multilayer laminated rotor is mountable on a shaft for rotation relative to a stator of a rotary electric machine arrangement. The rotor has a plurality of laminas, joined together, and voids for receiving magnets. An annular rotor section, which surrounds a shaft opening within which the shaft is receivable, extends between the shaft opening and a radially outer circumferential rotor surface. The annular section mentioned includes an undulating series of the voids in void groups extending from the radially outer circumferential rotor surface inwardly toward the shaft opening and then back toward the radially outer circumferential rotor surface, as well as a solid radially interior portion without any of the voids. Distal voids in the void groups include curved, arcuate, or recurved stress relieving features extending inwardly from radially innermost corner locations of the distal voids.
