Abstract:
A rotor is for a permanent magnet embedded-type motor and a motor using the same. A rotor for a permanent magnet embedded-type motor includes a rotor core having a rotary shaft fixed to a center and having a plurality of magnet insertion holes formed to be spaced along a circumferential direction and a plurality of pairs of permanent magnets, respectively, inserted into each of the plurality of magnet insertion holes in a V-shape to be gradually spaced apart from each other toward a radially outer side. Each of the plurality of magnet insertion holes includes a pair of inner sides facing each other, and a barrier hole is formed to expand an inner space of each of the magnet insertion holes to protrude from the pair of inner sides, respectively.
