ABSTRACT:
A compact and reliable structure of a multi-rotor synchronous machine which may be employed as a generator/motor for automotive vehicles is provided. The machine includes an outer rotor having permanent magnets, an inner rotor having permanent magnets disposed to be rotatable relative to the outer rotor, a stator core having armature coils interlinking with field magnetic fluxes produced by the outer and inner rotors, and a rotor-to-rotor relative rotation controlling mechanism. A relative angle between the outer and inner rotors is controlled within a given angular range by controlling the phase and quantity of current flowing through the armature coils to rotate the inner rotor relative to the outer rotor through the rotor-to-rotor relative rotation controlling mechanism, thereby changing the magnetic fluxes interlinking with the armature coils as needed.
