Abstract

Disclosed is an edgewise wound coil manufacturing device for manufacturing an edgewise wound coil. The edgewise wound coil manufacturing device is provided with: a plurality of corners; a core having a recess formed between each pair of adjacent corners, and around which a flat wire is wrapped; a rotating part that forces the core to rotate around the central axis of the core; guide parts that hold the flat wire therebetween in the thickness direction, while guiding the flat wire in such a manner that the flat wire wraps around the core; a first moving part that forces at least one of the guide parts and the core to move in the approaching/receding direction of the other; and a controller that adjusts the amount that the first moving part moves such that the edgewise wound coil achieves the desired shape.

Dependent claims

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.
