Servo Positioning Systems

Servo motors are great. But without a mechanical system, all they really do is turn in a prescribed (programmed) fashion. Speed, torque, current, force, position, and acceleration are all parameters that can be prescribed or derived to/from the servo motor. Two fine examples of mechanical systems that exploit the full features and value of a servo motor are EDrive's rod style linear actuators and Bell Everman's Servobelt linear motion system.

EDrive manufactures high precision, high force, high power density linear actuators. A ball screw or a roller screw translates the rotary servo motor motion from the servo motor into linear motion. Available either in-line or with a parallel offset that allows a 2:1 built-in reduction, these actuators are very versatile to fit your form when real estate gets tight on your machine build. Built to accept any motor, EDrive now offers an IP69K rated washdown actuator for food, pharma, and biomedical. More information is available: www.edriveactuators.com

Bell Everman's Servobelt linear system takes everything you thought you knew about timing belts and throws it out the window. Designed from the ground up, Servobelt can achieve one micron repeatability. The high accuracy of these units it independent of length. Suitable for grade AA granite applications, these actuators can easily be combined to build gantries as they are built on industry standard T-Slotted extruded aluminum. Bell Everman also makes high fidelity rotary stages. More information is available: www.bell-everman.com
