<p>In a stator of a rotating electrical machine of an embodiment, a slot 6 is formed along an axial direction 5 on an inner peripheral surface of a cylindrical iron core 2, and, on both inner walls of an open groove section of the slot 6, an engagement groove 9 is formed, and, with both side sections engaging with an inside of the engagement groove 9, a wedge 9 is so provided as to cover 10 the open groove section of the slot 6, and the stator is subjected to a resin impregnation process. Inside the engagement groove 7, a concave section 7A-1 is so formed as to be inclined at a predetermined angle with respect to a width direction of the wedge 9 engaging with the 15 engagement groove 7; and, on the wedge 9, a projection 9A-1 of an inclined shape that can be inserted into the concave section 7A-1 is so formed as to engage with the engagement groove 7.</p> |
