ABSTRACT:
A revolving-flux type motor is provided with a stator including a coil wound around an iron core and a rotor including permanent magnets fixed to an iron core. The permanent magnets of the rotor have peripheries which form a circle as a whole when fixed to the iron core and bottoms of which configurations are determined to form a flux density distribution of a sinusoidal waveform at a gap between the stator and the rotor. The iron core of the rotor has an outer peripheral configuration which allows face-contact with the bottoms of the permanent magnets.
