Rotating electrical machine

A rotating electrical machine, comprising:

• a rotor core having a permanent magnet placed therein;
• a stator core placed so as to face the rotor core in a radial direction and having a plurality of slots;
• and
• a concentric coil formed by concentrically winding a wire and placed in the slots of the stator core, the concentric coil comprises a first slot accommodated portion that is accommodated in a predetermined slot among the plurality of slots of the stator core and a second slot accommodated portion that is accommodated in a slot different from the predetermined slot among the plurality of slots of the stator core with both a first coil end portion and a second coil end portion between the first slot accommodated portion and the second slot accommodated portion, wherein
• a coil center is a line segment extending in an axial direction of the stator core and passing through the middle in the circumferential direction between the first slot accommodated portion and the second slot accommodated portion in the concentric coil,
• a center of a respective magnet pole is a line segment extending in the axial direction and passing through the middle in the circumferential direction between coil centers of concentric coils of the same phase located next to each other in the circumferential direction,
• the center of the respective magnetic pole is between the first slot accommodated portion and the second slot accommodated portion of both of the concentric coils of the same phase located next to each other in the circumferential direction,
• the concentric coil includes a first concentric coil and a second concentric coil which are of the same phase and are connected in series with each other, and a third concentric coil and a fourth concentric coil which are of the same phase and are connected in series with each other,
• the first concentric coil and the second concentric coil are connected in parallel with the third concentric coil and the fourth concentric coil, and
• each of coil centers of the first concentric coil and the third concentric coil is located at a respective position shifted by a distance to a first direction in a circumferential direction with respect to the center of the respective magnetic pole, and each of coil centers of the second concentric coil and the fourth concentric coil is located at a respective position shifted by the distance to a second direction opposite to the first direction side in the circumferential direction with respect to the center of the respective magnetic pole.
