Title:
TERMINAL CONNECTION METHOD FOR COIL, TWISTING TOOL, AND STATOR FOR ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/022338
Kind Code:
A1
Abstract:
In the present invention, input leader lines (14U1, 14U2, 14V1, 14V2, 14W1, 14W2) are configured of a slot insertion section (14b) which is located in an innermost-periphery-side layer of a slot insertion section of a coil segment (14) that is inserted into a slot (4) of a core (6) of a stator (2). The input leader lines are folded, together with a slot insertion section (12b) of another coil segment (12) located in the same layer, using a twisting tool (22), in the same direction as the circumferential direction of the core (6). Thereafter, joining sections (10), which are sites where end sections of slot insertion sections (12a) of an adjacent layer are joined, are guided in the outer peripheral direction by being bent so as to traverse gaps (21) between rows arranged in the radial direction, and the joining sections are connected to corresponding terminal members (15U, 15V, 15W).
