A permanent magnet-type motor includes a stator, on which coils are wound; and a rotor located on the inside of the stator, and having a plurality of magnet pairs arranged at positions thereof corresponding to the stator, each magnet pair including a high-energy magnet having a high residual magnetic flux density or a high amount of energy and low-energy magnets having a low residual magnetic flux density or a low amount of energy, thereby limiting the increase of the material costs of the magnets, improving the torque of the motor, and increasing the capacity of the motor. |
