摘要： PROBLEM TO BE SOLVED: To provide insulating paper between the same phases which can insulate unit coils from one each other in a simple structure and also can suppress cost increase due to an increase in working man-hour or material cost.SOLUTION: The insulating paper 11 between the same phases is composed of a pair of insulating paper bodies 12 and a coupling link 13 which connects the insulating paper bodies 12 with each other. At this time, the insulating paper body 12 has at least a width W that is larger than the thickness of the winding section of each unit coil, and also has a height H that is larger than the height of the winding section projecting outward in its radial direction from the end face 2a of a stator core 2, thereby having a form which can insulate adjacent unit coils. The insulating paper 11 between the same phases has such positional relation that the pair of insulating paper bodies 12 catches the stator core 2 from both sides in its axial direction when the coupling link 13 is inserted into a slot 6, whereby it insulates the unit coils from each other at both ends of the stator core 2.
