摘要： An axial gap-type permanent magnetic rotating machine comprises a rotor comprising a rotating shaft having an axis of rotation, a rotor yoke of disc shape radially extending from the shaft, and a plurality of permanent magnet segments circumferentially arranged on a surface of the rotor yoke such that each permanent magnet segment may have a magnetization direction parallel to the axis of rotation, and a stator having a plurality of circumferentially arranged coils and disposed to define an axial gap with the rotor. In the rotor, each permanent magnet segment is an assembly of two or more divided permanent magnet pieces, and the coercive force near the surface of the magnet piece is higher than that in the interior of the magnet piece.

摘要： A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to elastically deform the digitate hook and move it backward and to bring the hook digits in pressure abutment with the magnet block, thereby holding the magnet block in place on the platform.
