Abstract: A low power synchronous motor is disclosed having a rotor including a pair of rotor discs between which is sandwiched a permanent magnet which is polarized such that one of the rotor discs is a north pole and the other is a south pole. The stator includes an energizing winding having a core passing therethrough. A pair of complementary stator plates are secured at each end of the energizing winding to the core and are bent at right angles to form a copolanar stator air gap portion. The coplanar portion of the stator has a notched, circular air gap into which the rotor is positioned. The flat stator plates provide for easy assembly of the motor in a clock movement. The electrical energy coupled to the energizing winding is attenuated by means of a pair of impedance elements connected in series with the energizing winding and situated in the plug of the energizing circuit.
