CONSTITUTION: To uniformly pushing attach a layup core 1, a key-bar 5, to which both ends threads are cut, is connected to a dovetail 3 mounted to an outer circumference of the layup core 1 through a key 4, and fixed by clamping it in the laminating direction with massive plate bodies 7 from both surfaces of the layup core 1 by means of nuts 6. A metallic material with an excellent periodic damping characteristic or a metallic material with the coefficient of low linear expansion is used for the key-bar 5. Consequently, distortion and vibration due to a magnetic induction action are damped at the key-bar 5 before they spread to a foundation from the stator core 1, or the reduction of laminating pushing attaching force is controlled by restricting the thermal expansion of the stator core 1, thus decreasing the generation of noises due to magnetic vibration.
