Summary:PROBLEM TO BE SOLVED: To eliminate a defect that a belt pulley and a gear are cantilevered and held at an end of a rotor shaft, bent deformation is easily generated in the pulley and a gear fixing part and a driving mechanism is not miniaturized in a conventional outer circumference driving motor. SOLUTION: In an inductor motor, two groups of stators of an outer rotor motor are coaxially and continuously provided and both ends of the outer rotor as the belt pulley are rotatably held between the stators. An integral stator pole 15 is formed from one and another stator pole elements 15a, 15b for forming outer circumferences of two groups of the stators. One stator pole element comprises a connection 16c for connecting at least one crowning of an A phase magnetic pole 16a to a corresponding bottom of a B phase magnetic pole 16b. Another stator pole element is made the same as one stator pole element. One and another stator pole elements are arranged so as to be mutually displaced by 1/2 magnetic pole pitch in the circumferential direction.
