Abstract
The present invention proposes a thrust ripple mapping system in a precision stage with the thrust ripple mapping system comprising a moving stage, a load cell, a plurality of motors and a processing component. The load cell is coupled to the moving stage. The motors are employed in moving the load cell and the moving stage. The processing component takes a thrust force measurement at each of a plurality of moving increments of the load cell.
