摘要： A rotor (8) is deployed such that the rotor (8) becomes coaxially rotatable with a stator (2), A shaft (10) is fixed onto the axis of a rotor iron-core (9). 1-pole constituting magnet slots (11) are deployed into V-character pattern along an outer circumference portion of the rotor iron-core (9), Permanent magnets (12) are embedded into the magnet slots (11). For the 1 pole, the 2 pieces of same-polarity permanent magnets (12) are embedded into the V-character pattern. The configuration of each embedded permanent magnet (12) is designed as follows: From the thickness of the permanent-magnet edge portion on the inner-diameter side of the rotor iron-core (9), which becomes the center of the V-character pattern, the thickness of the permanent magnet (12) gradually increases toward the outer-diameter side of the rotor iron-core (9), which become the right and left edge portions of the V-character pattern. Simultaneously, curved lines (13) are provided on both edge portions of the permanent magnet (12).

摘要： A rotating electrical machine includes: a rotor (7) comprising a rotor core and a field winding wound round the rotor core; and a stator comprising a stator core (4) and a stator winding (6) wound round the stator core. The stator is arranged in opposition to the rotor with a predetermined spacing there between. The stator core is formed by punching a split piece, which comprises teeth for insertion of the stator winding there into and a core back on an outer periphery thereof, from a magnetic steel sheet, and laminating a plurality of those circular configurations in an axial direction, in which a plurality of the split pieces are arranged in a circle in a circumferential direction. The stator core is configured so that the magnetic steel sheets at the axial central region (11) thereof are higher in magnetic permeability in the diametrical direction than the magnetic steel sheets at the axial end region (10) thereof.
