Abstract: A rotating electrical machine comprises a stator and a rotor. The rotor includes a rotor iron core in which a permanent magnet is disposed. The rotor iron core comprises a connection part, a plurality of magnetic pole part, a first gap, and a second gap for injection of the adhesive. The connection part is configured to surround a rotational axis. The plurality of magnetic pole parts are provided in an outer portion than the connection part in a radial direction. The first gap is configured to penetrate along an axial direction between the magnetic pole parts in an outer portion than the connection part in the radial direction and in which the permanent magnet is fixed with adhesive. At least one of the second gaps is provided for each of the first gaps in communication with the first gap.

Abstract: The rotating electric machine includes a stator and a rotor. The rotating electric machine includes a rotor iron core including a plurality of magnetic pole portions in a circumferential direction, a plurality of permanent magnets provided on the rotor iron core, and a stator iron core including a plurality of teeth around each of which coil winding is wound. The stator iron core is configured in such a manner that the tooth facing the magnetic pole portion in the radial direction is substantially magnetically saturated by the permanent magnet in a non-energized state of the stator winding.
