Abstract
A method of manufacturing a stator core is disclosed. The method includes advancing a blank at each of a plurality of press cycles to form a segment at each of the press cycles and shaping the segments. Shaping the segments further includes activating a tooth punch, activating a mounting-ear punch, and activating an joint punch. The method also includes separating the segments from the blank.
