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.
