摘要： Disclosed is a permanent magnet type twelve-pole stepping motor of an inner rotor type or an outer rotor type. A stator comprises an annular shaped yoke portion, a stator iron-core having twelve stator main poles each having a plurality of small teeth on the tip end thereof and stator coils wound in the stator iron-core as three-phase winding. The stator rotatably supports a hybrid type rotor having a cylindrical permanent magnet that is sandwiched between a pair of rotors each having pole teeth around the circumferential surface to be opposite to the small teeth. Second, third, fourth and fifth harmonic components are removed by composing cogging torque of the respective phases by means of the three-phase twelve-pole construction. Any one harmonic component of the cogging torque among the second to fifth harmonic components is independently erased by making a difference between the small teeth pitch and the rotor teeth pitch, thereby the selected harmonic component is doubly erased.

The small stator teeth provided on the tip end of each stator magnetic pole are divided into sets of two or three small stator teeth and at least one pitch of the adjacent teeth is different from the other pitch of the other adjacent teeth, so that the vector sum of the quaternary harmonics of permeance in each set is substantially zero. The small stator teeth formed on the tip end of the stator pole are composed of two sets of three small stator teeth, and at least one pitch of the adjacent teeth is different from the other pitch of the other adjacent teeth, so that a vector sum of the tertiary harmonics of permeance of the three small stator teeth included in each of sets becomes substantially zero, and that a vector sum of permeances of axialsymmetric two small stator teeth on the quaternary harmonic plane of two sets becomes substantially zero.
