Abstract
PURPOSE:To obtain stable vibration of desired amplitude by using a variable voltage and variable frequency power source for an exciter. CONSTITUTION:Amplitude comparing circuit 6 compares amplitude (delta) of trough 2 with set amplitude deltas and supplies deviation signal deltas-delta to oscillating circuit 7. Further, amplitude characteristic phase difference comparing and discriminating circuit 13 compares vibration phase difference (phi) between vibrating motor 3 and trough 2 with common point phase difference pi/2 to discriminate which side of resonance characteristics the operation is carried out at, and then inputs the result to oscillating circuit 7. Next, oscillating circuit 7 receives both the inputs, and then outputs the frequency signal that corresponds to them. This frequency signal and the voltage signal that corresponds to it are applied to variable voltage and variable frequency power source I and control is so exercised that deviation deltas-delta will be zero. Thus, stable vibration of desired amplitude can be realized.
