A multiple-pole stepping motor includes M stator windings distributed on M/2 groups and coacting with a permanent magnet rotor for hybrid stepper and a soft iron rotor for a variable reluctant stepper. The two stator windings in each group are connected in series with different winding polarity. The uniform pole angle 360 DEG /M is to facilitate the winding process. The angles alpha and alpha ' are pitches between adjacent teeth of adjacent poles in the group, the angles beta and beta ' are pitches between adjacent teeth on adjacent groups, having a relationship with step angle t: <IMAGE> <IMAGE> In this relation m, n, m' and n' are integer greater than zero.
