Summary:PURPOSE: A rotor for permanent magnetic rotating device is provided to obtain high output and the thermal resistance by using the permanent magnet having high coercive force on the peripheral portion. CONSTITUTION: A rotor(1) comprises a plurality of permanent magnet segments(12) buried inside the rotor core. A stator(2) comprises a plurality of coils(13). The permanent magnet segment comprises the assembly of permanent magnet pieces. The coercive force near the surface of the respective permanent magnet is greater than the coercive force inside the respective permanent magnet.
