Linear Motors

Linear motors are linear direct drives with uniform, linear force. They are particularly suitable for positioning and feed movements of high dynamics and high accuracy, e. g. in

Compared to other linear drive systems (such as toothed-belt, ball-screw, or rack and pinion drives) a linear motor by ESR combines all the advantages of a direct drive and provides high acceleration and high speed with high stiffness and precision at the same time.
