摘要： A stator (1) comprises a frist stator portion (1a) and a second stator portion (1b), which consist of high-permeability material and are united by welding with low-permeability or nonmagnetic connections (1c, 1d) interposed. The stator includes a hole (2) provided with a pair of recesses (5a, 5b), which establish an initial phase angle (01) and serve as means for setting the torque to hold the rotor (3) magnetically. A field coil (7) is connected magnetically between the terminals of the stator (1) to form a tow-pole stepper motor for a timepiece.
