PURPOSE:To suppress the occurrence of a vibration or a noise by clamping only block cores of both ends of core legs with yokes of both ends by relatively short clamping members. CONSTITUTION:Block cores 1 and gaps formed of gap insulating members 2 having excellent compressing characteristic are alternately laminated to form core legs 3, and windings 4 are wound on the legs. The both ends of the legs 3 are contacted with yokes 5a, 5b, and side legs 6, 6 are so provided as to be interposed between both sides of the yokes 5a, 5b. Inserting holes 15 are formed at the core 1a and the yoke 5a, relatively short clamping member 17 secured with receiving fittings are inserted to the holes 15, and clamped through a clamping plate 8a with a nut 10 to rigidly clamp the core 1a and the yoke 5a. The core 1b and the yoke 5b are similarly clamped. Thus, the elongation of the member 17 is reduced due to the temperature rise, and a vibration or a noise can be suppressed without gap between the block core and the yoke. |
