A two-phase step motor with bifilar winding around the stator poles is connected to phases alpha and beta (90° apart) of a two-phase driver in a manner that maximizes torque at medium speed operation and minimizes vibrations. In particular, the coils that are wound around different groups of stator poles are connected in series. In one set, both coils are connected in a forward sense around the stator, while in the other set, the two coils are connected in opposite senses. All coils are energized in every phase of a pulse cycle. The properties are intermediate between that of convention series and parallel stator coil connections.
