Abstract
A rotating electrical machine includes a stator including a plurality of slots on which conductive wire is wound, and a rotor facing the stator and including a plurality of magnetic poles, wherein the rotating electrical machine is configured of fractional slot in which a denominator of an irreducible fraction obtained by dividing a number of the slots of the stator by a number of phases and a number of the magnetic poles of the rotor is equal to or greater than four, and ratio of magnitude of magnetomotive force of each phase is even in respective poles of the magnetic poles of the rotor.
