摘要： PURPOSE:To decrease a stress to be applied on a flexible part and thus to prevent a breakage of a connecting piece by providing a linear part coming in parallel with the directionin which a centrifugal force works on the flexible part consisting of a laminated material at both sides of a central arched section. CONSTITUTION:A flexible connecting piece 6 consisting of a laminated material which connects conductive pieces 10 for an adjacent field coil 3 electrically each other is provided with a linear part 6b2 coming almost in parallel with the direction in which a centrifugal force f works according to rotations of a rotor, thereby connecting a central arched section 6b1 and a bent 6c. A stress working on the flexible part can now be decreased thereby, therefore the connecting piece 6 is free from being broken for opening and closing operations repeated frequently, thus improving reliability.

摘要： PURPOSE:To prevent the slip or movement of a spacer and to avoid the generation of vibration by forming the spacer which is inserted between coils at the coil-end portions from laminated plates and arranging the felt into the outer portion of which resin is impregnated. CONSTITUTION:A felt 7 into which resin is impregnated is wound around a laminated plates 8, thereby a spacer 9 is formed. The spacer 9 is inserted between coils 3 whose coil-end portions are neighbouring, and the resin impregnated in the felt 7 is cured. In this method, since the resin is closely stuck to the concave and convexed portions of the surface of the coil 3, the slip or movement of the spacer 9 can be prevented, and the generation of vibration can be reduced.

摘要： PURPOSE:To prevent the spring pressure of the end of a wavy spring disposed in a box under a wedge for elastic support by rounding the end of the spring, thereby preventing the wear and the contamination of the contacting surface with the end of the spring and suppressing the formation of a slot. CONSTITUTION:A slot spacer 12 is formed at the intermediate to be superposed, and coil bars 1, 11 surrounded by an insulator 10 are disposed in the slot 4 of a stator core 5. Since the coil bars 1, 11 are elastically supported in the slot 4, a wavy spring 8 which is rounded at 8a is disposed at both ends of the wavy spring in a longitudinal direction of a box 9 under a wedge 6. The wear of the box 9 as the contacting surface is prevented by the round 8a of the end of the spring, the contamination in the machine due to worn chips is prevented, and the formation of the slot due to the wear is suppressed, thereby preventing the spring pressure of the end of the spring from decreasing.

摘要： PURPOSE:To alleviate the concentration of pressure on the contacting surface of a wavy spring with a box-shaped insulator by providing a groove having a curvature larger than that of the spring at a load point on the insulator having a wedge. CONSTITUTION:A nonmagnetic wavy spring 6 having a high resistance is provided under a wedge 7, the spring 6 is contained in a plurality of box-shaped insulators 5 divided in the laminating direction of a stator core 1 to suppress the electromagnetic vibration of a stator coil 2. A groove 5b is formed corresponding to the top of a continuous waveform spring 6 on the insulator 5, and a recess along the deflecting line of the spring is formed from the box portion 5b in the deep groove. A groove 7a is formed on the wedge 7 in coincidence with the deflecting line of the spring 6. In this manner, the contacting part of the spring with the insulator can be prevented from being worn due to vibration, and stable spring pressure can be transmitted to the stator coil.
