The NeoDryve is a self-tuning, load-compensating Vibratory Drive that uses Neodynium magnets instead of electromagnetic coils to produce vibration for part movement. That means no coils, no tuning, and no springs to wear. 

The NeoDryve draws less than 2 amps at 12VDC. It's unique vibration profile can move a full bed of heavy parts on just a few watts of power.
