Abstract

PURPOSE:To prevent the exposed parts of winding from adhering to the chips by machining the inside circumferential surface of a bracket and that of a stator core after contacting the beltlike film to the inside thereof in contact with the bottom surface of a coil end and the edge surface of a stator core. CONSTITUTION:The beltlike long and narrow films 30-1 and 30-2 are formed in ring to position so that they may contact to the bottom surface of the coil end of a winding 3 and the lateral surface of a stator core and that they may contact to the inside circumferential surface of notched parts 23 and 24. Then the inside circumferential surface of brackets 21 and 22 and those of the stator core are machined at the same time. Thus the winding 3 is completely sealed with the beltlike films 30-1 and 30-2 from the adhesion by the chips in the simultaneous machining.
