Abstract
PURPOSE:To prevent vibration and noise of an auxiliary pole with simple work by inserting curved wedges permitting plastic deformation and composed of a nonmagnetic material in the gaps at the tip sections of a magnetic pole opposing to an E-shaped auxiliary pole wherein the wedges are deformed after inserting the wedges to hold the wedges in the gaps. CONSTITUTION:Curved wedges 2 permitting plastic deformation and composing of a nonmagnetic material are inserted in the gaps at the tip sections of the central pole 4 and leg poles 3 of an E-shaped auxiliary pole 1. The practical width (b) of the wedges 2 is formed smaller than the gap (a) between the end edge section 4a of the central pole and that 3a of the leg pole for easy insertion of the wedges 2. And after inserting the wedges 2, external force A is applied to the curved projection sections of the wedges 2 to firmly hold the wedges 2 between the pole end sections 3a, 4a by extending the wedges 2 to the opposite sides for deformation. In this way, high- reliability noise-proof effect will be obtained with simple work.
