PERMANENT MAGNET TYPE DYNAMO-ELECTRIC MACHINE |
摘要 |
<p>The permanent magnet type reluctance electric motor includes a stator including a stator iron core and having armature coils placed inside slots, and a rotor provided with a plurality of magnetic barriers formed by cavities and placed on an inner side of the stator in such a manner that sections where a magnetic flux can easily pass (d-axis) and sections where a magnetic flux cannot easily pass (q-axis) are alternately formed, and made of a rotor iron core having permanent magnets in cavities, characterized in that the rotor satisfies a relationship of PL /2πRWqave ≧ 130, where Wqave [m] indicates an average thickness of the rotor iron core on an outer side in a radial direction of the rotor with respect to cavities arranged in a q-axis direction, L [m] indicates a width in a circumferential direction of the cavities, P indicates the number of poles and R [m] indicates the radius of the rotor.</p> |
