Abstract
Device and method for enabling independent tuning of frequency and amplitude of a reverse crankshaft motor. The reverse crankshaft motor provides periodic reciprocating motion based on periodic rotational motion from a rotational motor. The reverse crankshaft motor includes a crankshaft structure having first and second frames with a third axle arranged between them and connected to them by hinges. An amplituder is affixed to the third axle and may communicate with an external device. As the first and second frames move toward or apart from each other, the third axle moves radially toward or away from a central axis of the crankshaft structure. The position of the third axle determines the amplitude of the periodic reciprocating motion of the amplituder. By adjusting the position of the first and second frames, the operator may adjust the amplitude independently from the frequency of the periodic rotational motion supplied by the rotational motor.
