摘要： A stepping motor for an electronic timepiece comprises a permanent magnet rotor, a stator and a driving coil, having at least one static equilibrium point for the rotor. The driving coil is arranged to be energized by a current smaller than a driving current so that the stator is energized to required polarities of low flux intensity, whereby the static equilibrium point for the rotor is electromagnetically shifted to an arbitrary position to permit rotation of the rotor in any desired direction.
