Abstract:
An apparatus for manufacturing a segmented core for an electric machine, comprising:a support; a stacking head mounted on said support and having a magazine, a stripper blade proximate to the bottom of said magazine and a stripper blade actuator, said magazine being sized, dimensioned and positioned to receive a plurality of segments stacked one on top of the other in said magazine, said segments being stamped from a coated electric steel and each having an annular length and winding openings; a dial operatively associated with said stacking head having an arbor and means for rotating said dial, said arbor having an outer diameter approximately equal to an inner diameter of said segmented core and having radially extending blades being sized, positioned and dimensioned to be engageable with said winding openings; a support table supporting said stacking head and said dial, said support table having rollers disposed about said arbor at an outer diameter of said segmented core; and means operatively associated with said stripper blade for controlling said stripper blade actuator and said rotating means, said stripper blade actuator being controllable to extend said stripper blade into one of said plurality of segments at a bottom of said magazine to strip said segment from said magazine into said arbor such that said winding openings engage said blades and being controllable to retract said stripper blade, said rotating means being controllable to rotate said dial a first predetermined angular distance and a second predetermined angular distance, said first predetermined angular distance being equal to said annular length and said second predetermined angular distance being equal to half of said annular length, said controlling means being programmable to form a plurality of layers from said plurality of segments by rotating said dial said first predetermined angular distance, extending said stripper blade, and retracting said stripper blade until one of said plurality of layers is complete, and said controlling means being programmable to stagger said plurality of layers by rotating said dial said second predetermined angular distance between each completed layer.
