ABSTRACT:
The present invention provides a stroke control system for a vibratory conveyor which has a vibrating trough driven by a variable frequency motor. The stroke control system includes a transducer connected to the vibrating trough for sensing a vibration amplitude and for providing an output signal in response thereto. A motor control circuit is responsive to the transducer output signal for reducing the frequency of the motor when the output exceeds some threshold value.
