Claim:
1. A rotating electrical machine comprising: a rotor which is rotatably supported and which has, on its outer circumference, a plurality of convex-shaped salient pole sections arranged in a circumferential direction; a stator core which is disposed around the outer circumference of the rotor with an air gap formed therebetween and which has, on its inner circumference, a plurality of convex-shaped teeth arranged in a circumferential direction, with axial-direction grooves that are formed on radial-direction inner sides of the teeth and open to radial-direction inner sides and both axial-direction sides and extend in the axial-direction; field windings each of which is wound around each of the plurality of the teeth, each of the field windings forming a pole; and armature windings each of which is wound around each of the plurality of the teeth so as to be insulated from the field windings, forming a plurality of poles, a plurality of conductor rods that are disposed in each of the axial-direction grooves; and a plurality of conductor connection members that are disposed on each of both sides of axial-direction outer sides of the rotor, and to each of which axial-direction end portions of a predetermined number of the conductor rods are connected, and which make up one closed electrical circuit along with a plurality of the conductor rods, wherein the number of the teeth and the number of the poles formed by the field windings are equal, and a ratio of the number of the poles formed by the field windings to the number of the poles formed by the armature windings is equal to a predetermined ratio, and the number of the salient pole sections formed in the rotor is equal to (p
