PURPOSE:To obtain a motor of high precision, by systematizing a driving coil portion as unit and connecting it magnetically to the axial direction side of the magnetic pole means of a stator structure. CONSTITUTION:Right and left rotors 1 are fixed to a rotor shaft 12 making the phase shift of the teeth deviating at the angle of 180 deg., and a permanent magnet 3 magnetized in an axial direction is fixed between rotors 1 to complete a rotor structure. And a stator magnetic pole means 2 is fixed to a supporting structure 4 to complete a stator structure. And a driving coil 5 having a coil core 6 confronting to the stator magnetic pole means 2 is arranged in a coil unit frame 7 to organize a driving coil unit. Then, a step control unit 11 connected to the magnetic pole means 2 and the core 6 is built-in according to the magnetic pole means 2, and the driving coil 5 is arranged inside. As the result, the rotor 1 dimension in the depth direction can be made smaller and the effective area of the coil 5 can be enlarged. |
