METHOD FOR MANUFACTURING LAMINATED CORE

摘要

A method for manufacturing a laminated core comprising a step of punching a metal plate to form a stripe yoke core piece having a shape like a linearly developed yoke of a laminated core and having a coupling recess at the peripheral edge corresponding to the inner circumference, a step of winding and laminating the stripe yoke core pieces spirally and caulking them to form a yoke laminate, a step of punching a metal plate to form a pole core piece having a coupling protrusion at the root end, a step of laminating a predetermined number of pole core pieces and caulking them to form a magnetic pole laminate, and a step of winding a wire on the magnetic pole laminate, then fitting the coupling protrusion in the coupling recess, and thus coupling the yoke laminate and the magnetic pole laminate.
