ABSTRACT:
A method and a circuit arrangement for driving a two co-ordinate mechanical oscillator with the aid of a deformed rotating field of forces defined by a plurality of exciting and pick-up components. The power dissipation of the employed circuits is kept at a low level by operating the oscillator near the mechanical resonance frequency. The exciting signals are achieved by comparing phase shifted electrical signals derived from the mechanical motion of the oscillator in a first pick-up component with the undisplaced signals of the second directional component and by supplying the difference signal obtained therefrom to the second exciting components of the oscillator. This is continued to the next adjacent components until the ring is closed.
