Abstract
Provided is a rotating electric machine, including: a stator including: an annular core back; and a plurality of teeth projecting in a radial direction from the core back and being arranged in a circumferential direction, the plurality of teeth having slots each formed between the plurality of teeth adjacent to each other in the circumferential direction; and a rotor including: an annular rotor core which is arranged coaxially with the stator through a magnetic gap; and a plurality of magnetic poles arranged on the rotor core in the circumferential direction, wherein the rotor core includes a plurality of segment cores formed by dividing the rotor core in the circumferential direction with at division surfaces, and wherein the number of segments of the rotor core is different from a divisor and a multiple of the greatest common divisor of the number of poles of the rotor and the number of slots.
