ABSTRACT:
A method and apparatus for manufacturing laminated rotor cores in which lamina thickness variations are compensated for without disturbing the relative alignment of lamina shaft holes throughout the rotor core. The rotor core includes several truing laminas which are rotated to compensate for the lamina thickness variations and which include a central opening larger than the lamina shaft holes. The enlarged central opening in the truing laminas prevents overlap between the central opening and the shaft holes after rotation in spite of a lack of concentricity of the lamina shaft holes and central openings with respect to the laminas.
