摘要： PROBLEM TO BE SOLVED: To provide an IPM motor that effectively reduces the magnetic flux leaked from a permanent magnet, does not impede the flow of a magnetic flux generated on the stator side from a permanent magnet or the magnetic flux passing through rotor and contributing to a reluctance torque, and ensures extremely high torque performance, and to provide a rotor therefor.
SOLUTION: Permanent magnets 31 and 31 are buried, respectively, in two magnet slots which are arranged apart to spread toward the periphery of a rotor core so as to form a magnetic pole 30. The rotor 10 for IPM motors is provided with a plurality of magnetic poles in its circumferential direction, and a flux barrier 50A is formed in a non-crossed peripheral region HG of the rotor core which is a region corresponding to a peripheral interval between two magnet slots and is a region not crossing the magnetic flux generated on the stator side from each permanent magnet 31 and 31.
