The permanent magnet of 1 pair opposed across the packing manner and the magnetic circuit packing body null void of the packing

摘要

PROBLEM TO BE SOLVED: To provide a packing for a magnetic circuit, with which a leakage magnetic field escaping from an aperture of the magnetic circuit is reduced and the magnetic attraction acting on the packing plates is lowered, thus reducing the number of packing work steps.;SOLUTION: There are provided the packing plate 1 for a permanent magnet-type magnetic circuit, the packing plate has at least one non-magnetic layer 2 and at least one magnetic layer 3; and a method for packing the permanent magnet-type magnetic circuit, including a step of shielding at least a portion of an aperture of the permanent magnet-type magnetic circuit using at least one packing plate.;COPYRIGHT: (C)2006,JPO&NCIPI
