PROBLEM TO BE SOLVED: To provide a rotary electric machine which efficiently inhibits the occurrence of an eddy current in permanent magnets at the rotary electric machine including a stator and a rotor compared to a conventional rotary electric machine.SOLUTION: A rotary electric machine 2 includes a stator 11 and a rotor 12 supported so as to rotate relative to the stator 11. The rotor 12 includes multiple insertion holes 41a formed at equal predetermined intervals in a circumferential direction of the rotor 12; and permanent magnets 50 respectively inserted into the multiple insertion holes 41a and formed by various kinds of split magnets 51a to 51f having different dimensions. The dimension of the split magnet disposed in a portion of the rotor 12 where high heat radiation performance is achieved is set so as to be larger than the dimension of the split magnet disposed in a portion of the rotor 12 where heat radiation is conducted at a low level. |
