摘要:
A magnet type stepping motor which has (1) a stator with three-phase stator windings, and 6m pieces of stator main pole arranged side by side, where m is an integer and null1, the stator windings of one phase are wound around every two stator main poles among the 6m pieces of the stator main pole, wherein when the stator windings of one phase are excited with a direct current, m pieces of N pole and M pieces of S pole are formed alternately on the 6m pieces of stator main pole, and (2) a rotor of a cylindrical permanent magnet magnetized in the circumferential direction to form Z/2 pieces of N pole and Z/2 pieces of S pole alternately, where Z is the number of rotor poles.
