Abstract
A rotor for a rotary electric machine includes a plurality of magnetic poles in a rotor core, a side barrier as a magnetic air gap, an air gap section as a magnetic air gap. Each of the plurality of magnetic poles includes a magnet insertion hole, a permanent magnet. The side barrier is provided at a portion adjacent to a circumferential end face of the permanent magnet and includes a projection barrier portion projecting radially outwardly from an extension line extending from an outer peripheral surface of the permanent magnet. The air gap section is provided at an area which is spaced apart from the projection barrier portion and the magnet insertion hole and faces a peripheral edge of a circumferentially central side of the magnetic pole with respect to the projection barrier portion and a circumferential end of the outer peripheral surface of the permanent magnet.
