Abstract

PURPOSE: To make phase insulation to be sure, and improve the reliability, by using band state insulator and a plurality number of insulators with legs, and making phase insulation on the coil end part.
CONSTITUTION: After band state insulator 24 is inserted along all circumference of the coil end part 22 and it is fixed by binding yarn 25 together with coil, insulator 23 with legs 231 which are inserted in the slot at the part on which each phase coil is contacted in neiborhood of an outlet of the slot. Length 1 of body part 232 of the insulator 23 with legs is made to be selected so as to match to 3 ∼ 6 pitches of the slot. Thus, since phase insulation is made to be sure and at the same time length 1 of body part of insulator 23 with legs is made to be short, formation of coil can be facilitated.
