Abstract:
A saturation portion which is magnetically saturated during no-load operation of the rotary electric machine is formed in the rotor core at a position facing at least one of the first main surface and the second main surface of the permanent magnet when viewed in the axial direction. When viewed in the axial direction, the saturation portion includes at least one core protrusion firmed between the wall portion of the magnet accommodating hole and at least one of the first main surface and the second main surface of the permanent magnet such that a part of the rotor core extends in a direction intersecting the first main surface or the second main surface, and at least one nonmagnetic portion formed between the wall portion of the magnet accommodating hole and at least one of the first main surface and the second main surface of the permanent magnet.
