PROBLEM TO BE SOLVED: To provide a flux variable type rotating electrical machine which is reduced in size of a power generating section for generating drive forces of movable rotors, can change the effective flux amount of the rotating electrical machine, according to the operation state at high loading and high-speed rotation, and which can operate at high efficiency over a wide operating range. SOLUTION: The flux variable rotating electrical machine includes a stator 1 having a winding; the rotors which are arranged at the stator 1 so as to be rotatable with an air gap between the stator and themselves and divided into the first rotor 5 and the second rotor 6 in the rotation axial direction, and in which field magnets different in polarity are arranged alternately in the rotation direction; and a flux variable device JM, which varies the position in the relative rotation direction of the second rotor 6 with respect to the first rotor 5. The flux variable device JM includes a power generation section AC, a power transmission section DD which transmits a power generated at the power generation section AC to the second rotor 6, and a doubling mechanism BM which is interposed between the power generating section AC and the power transmission section DD and doubles the power generated at the power generation section AC.
