A permanent magnet ring shaped moment electric motor with two rotors based on the dephasing technology is provided in the present invention pertaining to the field of electric motor technology. Said electric motor includes: a rotor flange which has a two-ring structure, an external ring electric motor, an inner ring electric motor and a structure for installing and cooling the stator that is positioned in the center of the chamber between the external and inner rings. Wherein, the external ring electric motor and the inner ring electric motor are positioned respectively between the external and the inner rings of the structure for installing and cooling the stator and the rotor flange. The rotors of the electric motor are connected to a rotor flange together to form a whole. The stator teeth of the inner ring electric motor and the external ring electric motor have the structure of different tooth width, that is: the width of the top of the big teeth is identical to that of the magnetic pole. As a result, the
