Abstract:
A rotor for a flux-barrier-type reluctance motor having a plurality of poles formed in a circumferential direction includes a plurality of slits provided for each pole, a permanent magnet partially inserted into the slits in such a manner that magnetic poles of the permanent magnet are directed substantially orthogonal to the slit, a slit for a movable element disposed radially inside the permanent magnet disposed at an innermost position in a radial direction, and a movable element made of a magnetic material and inserted into the cavity, the movable element being capable of moving in the slit for the movable element in the circumferential direction. A radially inner side of the innermost slit into which the permanent magnet is inserted and radially outer and inner sides of both the slit for the movable element and the movable element are in a concentric circular-arc shape.
