Abstract:
1. An edgewise wound coil manufacturing device for manufacturing an edgewise wound coil, the device comprising: a core including a plurality of angle portions and recesses each formed between each pair of the adjacent angle portions, wherein a flat wire is wound about the core; a rotating part configured to rotate the core around a center axis of the core; a guide part configured to guide the flat wire such that the flat wire is pressed toward a deep side of the recess of the core and wound along the core while sandwiching the flat wire in a thickness direction; a first moving part configured to move one of the guide part and the core in an approaching/receding direction with respect to the other one of the guide part and the core; and a controller configured to adjust a moving amount of the first moving part such that the edgewise wound coil is formed into a desired shape, wherein the controller adjusts the moving amount of the first moving part such that the flat wire moves within a range smaller than a depth of the recess.
