发明名称 回転子及び永久磁石式回転機
摘要 A rotor (11) adapted for a large permanent magnet rotating machine (10) having high output and demagnetization resistance and the permanent magnet rotating machine (10) are provided. More specifically, there is provided a rotor (11) adapted for a permanent magnet rotating machine (10), the machine (10) comprising the rotor (11) and a stator (15) disposed with a clearance from an outer peripheral face of the rotor (11) and formed by winding a winding wire through a stator core (16) having two or more slots, the rotor (11) comprising one or more permanent magnets (13) in each of two or more insertion holes, the insertion holes being formed in a circumferential direction in a rotor core (12), wherein a magnetic coercive force in a stator-side surface region of each of the permanent magnets (13) is greater than that in an inner central portion by 300 kA/m or more, the inner central portion being an inner portion at a depth of at least 5 mm from every outer shape face of the permanent magnet (13).
