ABSTRACT:
A method of, and an apparatus for, constructing a laminated rotor for use in high speed stepping motors or the like. The apparatus consists of a rotatable carousel having a plurality of rotatable work stations each of which is carried to a plurality of operating stations. Lamina are punched from sheet metal stock and brought back into the stock and held in a friction fit. Sheet stock is then advanced to a stacking station where a lamina is forced onto a rotor shaft. The shaft is rotated thereafter in order to uniformly distribute any local metalurgical or planarity inconsistencies in the sheet stock throughout the laminated structure.
