Title:
ARMATURE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/145209
Kind Code:
A1
Abstract:
The present invention prevents the isolating coating of the terminal of a segment coil leg portion from being damaged when an inter-layer gap is enlarged. With this manufacturing method, a stator provided with a plurality of segment coils (40), both leg portions (42A, 42B) of which are inserted into each slot of a stator core and which are overlapped in the radial direction of the stator core into a plurality of layers (46A, 46B, 46C) and aligned in an annular shape, is manufactured. In this manufacturing method, a tool (74) having teeth (76A, 76B, 76C) is moved by a robot manipulator and thereby the teeth (76A, 76B, 76C) are inserted between the terminals of the leg portions (42) of the respective layers (46A, 46B, 46C). When inserted, the tool (74) is tilted in the insertion direction of the teeth (76A, 76B, 76C) and around the axis orthogonal to the radial direction and thereby the ends of the teeth (76A, 76B, 76C) are made non-contact with the insulating coatings of the terminals of the leg portions (42).
