<p>A rotor of an electrical rotating machine includes a first rotor core, a second rotor core which overlaps the first rotor core in an axial direction, a non-magnetic substance layer which is interposed between the rotor cores, and a plurality of permanent magnet portions which are embedded in each rotor core. Each of the rotor cores includes a plurality of flux barrier portions and a plurality of effectual magnetic flux portions which are alternately arranged on an outer circumferential surface thereof. The flux barrier portion of the first rotor core overlaps both of a part of the flux barrier portion of the second rotor core and a part of the effectual magnetic flux portion of the second rotor core, in the axial direction. As a result, in the adjacent rotor cores, the effectual magnetic flux portions of which magnetic poles on the radially outer sides are different from each other do not overlap each other in the axial direction. Thereby, short-circuiting of the magnetic flux is prevented from occurring between the adjacent rotor cores.</p> |
