Abstract
The described technology relates to a rotor having a flux filtering function and a synchronous motor comprising the same. The rotor includes a rotor iron core, a plurality of permanent magnets and a plurality of conductor bars. The rotor iron core has a rotary shaft insertion hole, formed in the center thereof, into which a rotary shaft is inserted, a plurality of permanent magnet insertion holes being formed in the circumference of the rotary shaft insertion hole, and a plurality of conductor bar insertion holes are uniformly formed in a region between the plurality of permanent magnet insertion holes and the outer surfaces thereof. The plurality of permanent magnets are respectively inserted into the plurality of permanent magnet insertion holes, thereby forming N and S magnetic poles of the rotor. Additionally, the plurality of conductor bars are respectively inserted into the plurality of conductor bar insertion holes.
