Rotor for axial air gap-type permanent magnetic rotating machine |
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. |
