The Slotted ram also may be topologically transformed to make a rotary motor capable of generating very large torques directly, with only one moving part. This is of special interest to ship designers who require a reliable and fast-response rudder actuator that is electrically driven.
Finally, the ram can designed in configurations that actually have curvature to their length, and as the slot can also spiral along the length of the ram, the Slotted Ram can apply force fully in three dimensions.
