Original Abstract Submitted
A method of forming a stack of laminates for a stator includes stamping in sequence a plurality of annular stator laminates from a continuous sheet of metal. The annular stator laminates each including an interior surface with a plurality of winding teeth and an exterior surface with a plurality of circumferentially spaced radially protruding ears wherein the plurality of circumferentially spaced radially protruding ears of each adjacently formed annular stator laminate is circumferentially offset from the circumferentially spaced radially protruding ears of immediately adjacent annular stator laminates. Clocking each of the annular stator laminates a predetermined angular rotation relative to an adjacent annular stator and stacking the annular stator laminates with the circumferentially spaced radially protruding ears aligned within the stack.
