Claim 0:
1. A rotating electrical machine comprising:
a rotor which includes a magnet unit and is retained to be rotatable; and
a stator which is equipped with a stator winding made up of a plurality of phase windings, the stator being arranged coaxially with the rotor,
wherein the stator winding includes magnet facing portions which overlap the magnet unit in an axial direction and turns each of which joints a first one and a second one of the magnet facing portions used for the same phase together axially outside the magnet unit, the first and second ones of the magnet facing portions being away from each other with a given number of the magnet facing portions interposed therebetween,
wherein the first and second ones of the magnet facing portions which are used for the same phase and joined together by one of the turns are arranged on the same pitch circle defined about a center of the rotor, and
wherein if an arrangement pitch that is an interval between centers of the circumferentially adjacent magnet facing portions arranged on the same pitch circle in the circumferential direction is defined as Ps, a diameter of the same pitch circle is defined as Ds, and Ds/Ps is expressed by τ, a relation of 24<τ<34 is met.
