FIELD MAGNETON, MANUFACTURING METHOD THEREFOR, AND ROTATING ELECTRICAL MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a field magneton which is high in permeability and has less iron loss.;SOLUTION: An axial gap type rotating electrical machine 10 is equipped with a field magneton 20, which rotates about a rotating shaft 50a, and an armature 30, which faces the field magneton 20 on the rotating shaft 50a. The field magneton 20 has a field generator 28. The field generator 28 has a permanent magnet 22 and a rotating magnetic core 24, which covers it from the side of the armature 30. The rotating magnetic core 24 is constituted of arcuate steel plates that are stacked vertically on the rotating shaft 50a, at the position provided. The outside diameter, centered at the rotating shaft 50a, of a magnetic pole face 21a on the side of the armature 30 of the rotating magnetic core 24, is larger than a value of added twice the thickness of steel plates to the outside diameter of the magnetic pole of the armature 30.;COPYRIGHT: (C)2010,JPO&INPIT
