<p>PROBLEM TO BE SOLVED: To provide a rotor of a rotary electric machine capable of securing sufficient strength while securing effects for restraining leakage of a magnetic flux and reducing inertia.SOLUTION: A rotor 10A comprises: a rotor core 11 having pairs of two magnet housing holes 12 arranged in a V-shape so that a distance between the opposed holes gets larger toward an outer periphery side; and plural pairs of magnets 13 housed in the pairs of the magnet housing holes 12 arranged in the V-shape, and respectively forming each one magnetic pole. The rotor core 11 has: a pair of flux barriers 16 enlarged toward a center axial line O of the rotor core 11 from an end on a magnetic pole center side of each of the pair of magnetic housing holes 12; and a center bridge 15 formed between the pair of the flux barriers and extending in a radial direction. In the center bridge 15, circumferential width of an inner side portion 15a positioned on an inner side in the radial direction is made larger than that of an outer side portion 15b positioned on an outer side in the radial direction.</p> |
