PROBLEM TO BE SOLVED: To prevent such a state of affairs that a magnetic flux permeates mutually in three or more rotors and a magnetic resistance increases, even in providing a rotating electrical machine with three or more rotors to make it multiaxial. SOLUTION: For axial rotors 1 and 2, permanent magnets 5 and 6, in which N and S poles are arranged alternately in its circumferential direction, are counterposed coaxially so as to face each other, and are supported so that they can rotate individually around a common axis O. A stator 7 is interposed with a specified axial gaps between the rotors 1 and 2 (between the permanent magnets 5 and 6), and the stator 7 is constituted in an annular form by toroidally winding armature coils 10 on many yokes 8 extending in the circumferential direction of the axial rotors 1 and 2. On the outer diametrical side of the stator 7, radial rotors 11 are arranged coaxially with a specified radial gap, and on the inner diametrical side of the stator 7, radial rotors 12 are arranged coaxially with a specified radial gap, and these rotors 11 and 12 are supported so that they can rotate individually around the axis O. Permanent magnets 13 and 14, in which N and S poles are arranged alternately in its circumferential direction, are provided on the inside periphery of the rotor 11 and the outside periphery of the rotor 12.
