Abstract
A rotor described herein includes a plurality of flux barriers that include at least one magnetic path formed between a plurality of slits. The flux barriers are arranged in a circumferential direction at a predetermined interval. Adjacent flux barriers are concatenated on an inner circumferential side by an annular connector provided on the inner circumferential side, and are separated on an outer circumferential side by openings provided on the outer circumferential side. The rotor also includes a permanent magnet at least partially embedded within the annular connector.
Claims21
A rotor for a reluctance motor, said rotor comprising:
- a plurality of flux barriers including at least one magnetic path formed between a plurality of slits, the flux barriers arranged in a circumferential direction at a predetermined interval, wherein adjacent flux barriers are concatenated on an inner circumferential side by an annular connector provided on the inner circumferential side and adjacent flux barriers are separated on an outer circumferential side by openings provided on the outer circumferential side;
- and
- a first permanent magnet at least partially embedded within the annular connector and magnetized in a radial direction of the rotor.
A reluctance motor comprising:
- a stator that includes a stator core having a plurality of stator teeth;
- and
- a rotor configured to rotate with respect to the stator about a central axis that extends through a center of the rotor from a first end of the rotor to a second end of the rotor, the rotor comprising:
- a rotor core that includes an inner surface and an outer surface coaxially arranged about the central axis;
- a plurality of flux barriers defined within the rotor core, the flux barriers extending axially through the rotor core from the first end to the second end;
- an annular connector included within the rotor core, wherein adjacent flux barriers are concatenated on an inner circumferential side by the annular connector;
- a plurality of openings defined within the rotor core along the outer surface of the rotor core, wherein adjacent flux barriers are separated by an opening of the plurality of openings;
- and
- a permanent magnet at least partially embedded within the annular connector and magnetized in a radial direction of the rotor.
A rotor comprising:
- a rotor core having an inner circumferential side and an outer circumferential side, the rotor core including a plurality of flux barriers arranged in a circumferential direction around the rotor core at a predetermined interval, wherein flux barriers that are adjacent to each other in the circumferential direction are concatenated on the inner circumferential side by an annular connector that includes a permanent magnet at least partially embedded therein and magnetized in a radial direction of the rotor, and the adjacent flux barriers are separated by openings in the rotor core that extend to the outer circumferential side.
