Abstract
This disclosure relates to a method for manufacturing a laminate used for manufacturing a laminated core including a circumferential yoke part and a plurality of magnetic pole parts radially extending from the yoke part. This method includes: feeding a metal sheet drawn from a roll thereof to a progressive die; stamping out a plurality of workpieces from the metal sheet in the progressive die, wherein each of the workpiece comprises a temporarily-interlocking portion between adjacent magnetic pole portions; and stacking the workpieces to integrate these workpieces together by the temporarily-interlocking portion to obtain the laminate.
