Abstract
PURPOSE:To reduce torque ripple by giving a difference between an inserting gap of an outer stator yoke and a frame, and an inserting gap of an inner stator yoke and a frame. CONSTITUTION:A stepping motor has a rotor 1 having a cylindrical permanent magnet 2 applied the multi-electrode magnetization to the periphery and the disc-like in and out stator yokes 3-4 having the pole teeth 3a and 4a, and the in and out stator yokes 3-4 are located in such a state that each of the pole teeth 3a and 4a is penetrated into each other. The outer diameter of a disc section 3b of the inner stator yoke 3 has a relation of an intermediate insertion against an inside diameter dimension of a frame 7, and an outer diameter dimension of the disc section 4b of the outer stator yoke 4 is a clearance insertion and support the gaps g. The stator coils 5 wound on an annular coil bobbin 6 are located between the in and out stator yokes 3-4. Accordingly, the occurrence of the deviation in the stopping position is eliminated by conforming a magnetic path of the flux from the permanent magnet 2 to a generation magnetic path at the time of stator coil excitation.
