ABSTRACT:
A drive circuit for an electromechanically excited vibratory conveyor responds to the inductance fluctuations of the conveyor drive coil due to mechanical vibration so as to feed the coil with drive pulses having a repetition frequency commensurate with the natural frequency of the mechanical vibration. Phase and duration of the drive pulses are automatically regulated.
