ABSTRACT:
A permanent magnet type rotating machine includes a stator core provided on an inner periphery thereof with armature windings, a rotor core, a plurality of permanent magnets arranged on an outer periphery of the rotor core, and a magnetic ring arranged between the permanent magnets and a stator. The magnetic flux running from the permanent magnets to the stator core through a gap, can be increased by a reduction in magnetic reluctance due to the magnetic ring inserted between the gap and the permanent magnets. The magnetic ring is fitted on either one of the outer peripheries of the permanent magnets and the inner periphery of the stator core.
