Patent ID: 7042127

Claim:
A permanent magnet embedded motor comprising: a rotor which is provided with a plurality of slits and a plurality of permanent magnets embedded into the slits, the slit comprising: a permanent magnet embedded part into which the permanent magnet is embedded in a direction perpendicular to the radial direction of the rotor; and an “L”-shaped air gap part integrally provided on both ends of the permanent magnet embedded part; and a stator which is provided with an iron core having a plurality of slots to which a coil is wound and is arranged to face the rotor via a gap, wherein an angle “θ 1 ” for one pole of the rotor and an angle “θ 2 ” of the “L”-shaped air gap part are set to be 0.1≦θ 2 /θ 1 ≦0.3.
