Title:
METHOD FOR PREVENTING LOCATION ABERRATION OF INSULATION SHEET AND DEVICE FOR PREVENTING LOCATION ABERRATION OF INSULATION SHEET
Document Type and Number:
WIPO Patent Application WO/2019/189934
Kind Code:
A1
Abstract:
According to the present invention, each of location aberration preventing rods (14, 16) disposed in a radial shape circumferentially on both sides of the axial direction of a core (2) has bifurcated convex portions (14A1, 14A2, 16A1, 16A2) inserted into a slot (4). Each of the convex portions has flanges (14A1a, 14A2a, 16A1a, 16A2a) on both sides when viewed in the circumferential direction of the core (2). When the location aberration preventing rods (14, 16) move to a radially inner side of the core (2) after an insulation sheet (8) is inserted into the slot (4), an edge of the insulation sheet (8) is covered by the flanges (14A1a, 14A2a, 16A1a, 16A2a) so that contact between a coil and the edge when the coil is inserted is prevented, and location aberration of the insulation sheet (8) in the axial direction of the core (2) is also prevented. The location aberration preventing rods are installed only on a distal end in the insertion direction of the insulation sheet (8).
