Abstract

An electronic drive arrangement for time measuring devices has a transistor controlled cartridge shape bending oscillator with at least one side having an electrically conducting layer. A synchronized motor is provided whose stator carries on one shank the cartridge shaped bending oscillator and on the other shank an inductance. The air gap between the two shanks is bridged by a ferromagnetic element functioning as a magnetic shunt. The element is so made that the energy is great enough to drive the bending oscillator as well as the motor. The efficiency is greatly increased by this arrangement, and by virtue of the integrated synchronized motor can be used in inexpensive clocks and watches.
