摘要： This invention relates to electric clocks and chart recorders driven by crystal controlled electric motors. The motor includes two stator plates, a rotor and a drive coil surrounding the legs of the stator plates. The rotor carries a pinion which drives the first gear of a mechanical gear train located between two side plates consisting of synthetic resin material. One of the side plates carries at least one bearing for the rotor and a plurality of projections which fit into holes in the stator plates and serve to position the stator plates in relation to the rotor. Electric pulses are supplied to the drive coil by an electronic frequency divider circuit having a push-pull output stage; a zener diode is connected in parallel with the power supply to the divider circuit and the drive coil to enable the motor to operate satisfactorily over a range of supply voltages. For this purpose, the drive coil preferably has a resistance of more than 1K and a resistor is connected in series between the supply and the zener diode.
