PROBLEM TO BE SOLVED: To provide a variable characteristic rotating electrical machine that has little field loss even at large torque and high output and ensures a high efficiency and a long rated time. SOLUTION: A first rotor 1, wherein N-pole permanent magnets 5a and S-pole permanent magnets 5b are alternately arranged in the peripheral direction, and a second rotor 2, wherein N-pole permanent magnets 6a and S-pole permanent magnets 6b are alternately arranged in the peripheral direction, are disposed opposite to each other so that the permanent magnets in the respective rotors may face each other. Between these rotors, a stator 7 is interposed which consists of an armature core 9 having yokes 8 extending in the revolving direction of the rotors and armature windings 10 wound around the yokes 8. In order to change the characteristics, an amount of interlinking field magnetic flux of these rotors with armatures 9 is adjusted by phase control of the first and second rotors 1 and 2 in the revolving direction to make possible the change in characteristics.
