Claims

[Scope of Claim for Utility Model Registration] A ground insulating sheet for insulating between the coil and the iron core is arranged along the inner surface of the slot of the iron core, and inside the slot, inside the above ground insulating sheet, there is a lower opening and an upper opening. The coil is inserted while being insulated by interposing an interlayer insulating sheet between the layers, and outside the slot, an end coil interlayer insulating sheet is interposed between the end coil layers of the lower and upper coils, and In the insulating structure of a two-layer coil of a rotating electrical machine, in which a wedge is disposed on the opening side of the slot to hold the two-layer coil in the slot, the wedge is placed in place of the interlayer insulation sheet. A rectangular sheet having a width exceeding the entire circumference of the upper coil and a length slightly exceeding the length of the slot is placed between the upper and lower coil layers and between the end coil layers. and a trapezoidal sheet protrusion extending from both ends of the sheet base, the width of the rear end and the tip slightly exceeding the coil diameter of the end coil, and the width becoming narrower from the rear end to the tip. An insulating structure for a two-layer coil of a rotating electrical machine with a composite insulating sheet consisting of two pieces interposed.
