Title: ROTOR FOR ROTARY ELECTRIC MACHINE, ROTARY ELECTRIC MACHINE, AND VEHICLE
Abstract:
Provided are a rotor for a rotary electric machine, a rotary electric machine, and a vehicle, with which the concentration of stress generated in magnet insertion holes of a rotor core can be alleviated, enabling high-speed rotation. This rotor 250 for a rotary electric machine is configured so as to be equipped with a rotor core 252 provided with a plurality of magnet insertion holes 253 for each magnet pole, and permanent magnets 254 inserted into the magnet insertion holes. Bridge parts 260 are provided mechanically connecting a rotor core section 256 on the outer circumferential side of the magnet insertion holes 253 and a rotor core section 263 on the inner circumferential side. On the outer circumferential side of the bridge parts 260 there are two inflection points 266a and 266b.
