VIBRATORY CONVEYOR ABSTRACT A drive and drive controller for a vibratory conveyor, wherein the drive comprises, a pair of pole pieces offset along a direction of action of the drive, and moveable in the direction of action of the drive when energized by a power signal. Preferably, one of the pole pieces is mounted to a tray portion, and the other to a kinetic balancer portion, of the conveyor. The power signal comprises a series of pulse trains of controllable frequency and duration, whereby the drive unit may be vibrated at a controllable frequency and amplitude so that the vibratory conveyor may be readily tuned to optimal performance. Optionally, the voltage level of the power signal may be reduced by an autotransformer in series with the power signal to independently control the power level.
