摘要： A rotor is provided for a permanent magnet type rotating machine having a stator 1 with armature windings 11. The rotor 3 includes a rotor core 31 and a plurality of permanent magnets 32 arranged in the rotor core 31 so as to negate magnetic flux of the armature windings 11 passing through interpoles 3b. The rotor 3 is constructed so that the average of magnetic flux in an air gap 2 between the rotor 3 and the stator 1, which is produced by the permanent magnets 32 at the armature windings' de-energized, ranges from 0.1 [T] to 0.7 [T] and the ratio (Lq/Ld) of self-inductance of the magnetic portion in a hard-magnetizing direction (q-axis) to self-inductance in an easy-magnetizing direction (d-axis) under a rated load condition ranges from 0.1 to 0.8. Under these conditions, it is possible to realize the rotating machine which operates as an induction machine at the machine's starting and also operates as an synchronous machine at the rated driving due to smooth pull-in.

摘要： A permanent-magnet rotating electrical machine includes a stator with an armature coil and a rotor arranged to rotate with a predetermined air gap with respect to the stator. The rotor includes a rotor core. Permanent magnets are arranged inside the rotor core on an outer circumferential side, or at the surface of the rotor core. The permanent magnets each are divided into a plurality of segments in an axial direction along a dividing face. The dividing face and an end face of the permanent magnet facing a circumferential direction form acute angles to define narrowed areas to suppress generation of eddy currents in the permanent magnets, prevent deterioration of the permanent magnets, and improve efficiency of the permanent-magnet rotating electrical machine.
