Title:
PROCESS AND MOLD FOR PRODUCING FERROMAGNETIC CORES OF ELECTRIC MOTORS
Document Type and Number:
WIPO Patent Application WO/2010/125594
Kind Code:
A8
Abstract:
A process and a blanking mold are described for the production of a ferromagnetic core for electric motors formed by a plurality of segments. The laminations are blanked from a sheet of ferromagnetic material and stacked in an accumulation chamber of the blanking mold, along which they advance until a segment constituted by a stack having a preset number of laminations is formed, which is mechanically connected to an adjacent segment, thereby forming a rectilinear sequence of segments. The segments are hinged to each other with the possibility of mutual rotation to allow the sequence of segments to be brought from the rectilinear condition to a closed circular configuration.
