PERMANENT MAGNET FOR MAGNETIC FIELD POLE, MANUFACTURING METHOD THEREOF, PERMANENT-MAGNET TYPE ROTATING ELECTRIC MACHINE EQUIPPED WITH PERMANENT MAGNET FOR MAGNETIC FIELD POLE

摘要

PROBLEM TO BE SOLVED: To reduce cost, by dispensing with finishing processing to a permanent magnet for a magnetic field pole, after a plurality of divided magnet pieces are integrated.;SOLUTION: The permanent magnet 3 for the magnetic field pole is obtained, by connecting and fixing the plurality of magnetic pieces 7 with an insulating member 9 by dividing and breaking the permanent magnet 5 for the magnetic field pole with a groove 5a as a boundary and by making the divided permanent magnets as the plurality of magnet pieces 7. When the permanent magnet is divided, a region being one magnet piece 7 among the divided magnet pieces is pressed and broken with the groove 5a, as the boundary in a state where the other region other than the divided one magnet piece 7 is fixed and held by a jig. The insulating member 9 is constituted by mixing non-conductive particles 11, such as, glass beads in an adhesive 10.;COPYRIGHT: (C)2011,JPO&INPIT
