ABSTRACT:
In an electromagnetic driving device for example for an electric clock, a driving polar rotor arranged in the magnetic field of a coreless field coil drives a rotatable following polar rotor so that in their static states the poles of the rotors are shifted at a definite angle in the direction of the magnetic field of the coil. The driving polar rotor is rotatably supported within a bobbin on which the coil is wound and is retained in the bobbin by a rotor retaining part which is held in place by a printed circuit plate which controls the current flowing through the coil.
