A slot-less electromotor having inner and outer rotors as well as the ring-type winding settles the problem that the conventional slot-less motor always appears to have insufficient torque at low speed, low efficiency and instability in operation. The iron core is of slotless construction, with winding coils wound on iron core, and inner and outer peripheries of which facing respectively inner and outer magnets and inner and outer magnetic yokes, together forming a complete system of electromagnetic induction circuit. Inner and outer magnets inner and outer magnetic yokes and rotating shaft are joined together by screws to form the rotor. Iron core is fixed with positioning plate and positioning seating and assembled with bearing housing to form the stator. Present invention has advantages of large power/volume ratio, wide speed regulating range and good performance at low speed. <IMAGE>
