Title:
METHOD FOR MANUFACTURING STACKED BODY, AND DEVICE FOR MANUFACTURING STACKED BODY
Document Type and Number:
WIPO Patent Application WO/2019/203217
Kind Code:
A1
Abstract:
A method for manufacturing a stacked body (1A) includes: stacking a plurality of electrical steel plates (4) to form a stacked block (5), and overlaying a plurality of the stacked blocks (5) in a stacking direction (D1) of the electrical steel plates (4) to form one provisional stacked body (1B); forming a rotationally stacked stacked body (1C) in which at least one of the stacked blocks (5) in the provisional stacked body (1B) has been rotated relative to another about an axis in the stacking direction (D1); and adjusting the stacked number of electrical steel plates (4) in the formation of the stacked blocks (5) on the basis of thickness information relating to the thickness of the rotationally stacked stacked body (1C). Adjusting the stacked number on the basis of the thickness information includes acquiring pre-rotational stacking thickness information, which is the thickness information before the rotationally stacked stacked body (1C) has been formed, and, if the pre-rotational stacking thickness information is lower than a preset pre-rotational stacking lower limit, increasing the stacked number to make the thickness information equal to or greater than the pre-rotational stacking lower limit.
