PROBLEM TO BE SOLVED: To provide a permanent magnet embedded motor that is practically permissible even if a permanent magnet of weak magnetic force is incorporated. ! SOLUTION: A permanent magnet embedded motor includes a stator having a coil, a rotor body 2 rotatable along the stator, and having a first permanent magnet 22 that has a plurality of poles P,...,P, and arranged so that one pole faces the stator, and a first permanent magnet arrangement section 21 where the first permanent magnet 22 can be arranged, corresponding to each pole P, and a yoke 3 located on at least one end side of the rotor body 2 in the axial direction, and composed of a magnetic material at least partially, and having a second permanent magnet arrangement section 31 where the second permanent magnet 4, arranged so that one magnetic pole faces the axial direction, can be arranged, corresponding to each pole P. A space exists between the facing surfaces of the rotor body 2 and yoke 3, at a radially outward position corresponding |
