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, wherein 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 on one side in a circumferential direction with respect to a center of a magnetic pole, and each of coil centers of the second concentric coil and the fourth concentric coil is located on the other side in the circumferential direction with respect to the center of the magnetic pole.
