Abstract
An apparatus and method for producing motor laminations from blanks uses a servo-controlled linear transport mechanism for transporting blanks a fixed stroke distance to a notching station wherein the notching station includes a stationary index spindle and movable punch head which adjusts for accommodating blanks of varying diameters. A lamination removal mechanism removes and transfers a notched lamination from the notching station to a lamination carrier by traveling a fixed stroke distance. Different diameter blanks are facilitated by adjusting grippers and the punch head while the stroke distances remain unchanged. The linear transport mechanism and the lamination removal mechanism move independently to transfer blanks and laminations at different times to improve blank throughput.
