Abstract:
Provided is a rotating electric machine. This rotating electric machine includes a stator and a rotor, and the rotor includes: a rotor core having formed therein a magnet insertion hole group; and a permanent magnet group. In the rotor core, a first magnetic slit and a second magnetic slit are formed. In the second magnetic slit, a first magnet magnetic flux guide path connecting a first q-axis magnetic path and a second q-axis magnetic path is arranged. When an angle between a straight line passing through a first intersecting point and a radial center point and a straight line passing through a second intersecting point and the radial center point is set as θ1, the number of pole pairs is set as P, a natural number is set as m1, and n1 is set as a natural number smaller than m1, the following expression: θ1=2π×n1÷{P×(2m1−1)} [rad] is satisfied.
