<P>PROBLEM TO BE SOLVED: To provide a rotating electrical machine which is able to have magnetic reluctance reduced and magnetic flux increased. Ž<P>SOLUTION: In the rotating electrical machine including two rotors, differing in number of magnetic poles which are driven independently driven, in the rotor larger in the number of magnetic poles of the two rotors, either an N-pole or an S-pole magnets is smaller in the volume of each magnet with respect to the other.
