PURPOSE:To control electromagnetic vibration in the radial direction of coils, by a method wherein semiconductive sheet fixed substance which is laminated with heat-resisting synthetic paper and rubber-formed elastic unit is inserted between a slot side wall and the coils. CONSTITUTION:Two layers of stator coils 2 are contained in the slot 1 of a stator core 5, and are kept and fixed in the radial direction by a wedge 4 and a spacer 3. Fixing member 6 is inserted between the core 5 and the coils 2 in the slot 1. The fixing member 6 is organized by coating a heat-resisting rubber elastic unit 6b of the thickness t2 uniformly on one surface of semiconductive heat-resisting synthetic paper 6a excellent in elasticity in the direction of the thickness t1, and the thickness t1 of the heat-resisting synthetic paper 6a and the thickness t2 of the rubber elastic unit 6b are set in relation to (t1+t2)>A/2 for the space A in the slot 1. |
