Abstract

The electromagnetic stepping motor of the invention comprises two rotors coupled to a common transmission wheel. The magnetic circuit of the stator is arranged so as to subject the respective rotors to fluxes of opposite senses phi 1, phi 2 when the winding is energized. The magnetization sense of the first rotor is opposite to the magnetization sense of the second rotor in a manner such that they turn in the same sense when subjected to said opposite sense fluxes. This arrangement permits either a diminution of the volume or a decrease in energy consumption of the motor and at the same time increases the security of running thereof in the presence of external magnetic fields. Such a motor is particularly adapted to small volume horological applications.
