Servomotors

The high performance of brushless motors combined with the robust mechanical abilities of planetary roller screws make the GS series linear actuators the perfect choice for demanding linear motion applications.

The roller screw s unique design for transmitting forces enables it to carry a heavy load for thousands of hours in the most arduous conditions. The internal brushless motor offers high acceleration and cycle rate capability, as well as precise positioning and smooth motion. The design of the patented GS series offers the  most compact package possible by making the planetary roller screw and brushless motor an integral unit.

These innovative devices do away with the complex support systems (hydraulic power supplies, servo-valve, filtering, plumbing, etc.) and  high maintenance  associated with electronically controlled fluid power  actuators. Roller screws and actuators offer simplified  control due to their all-electric nature and greater (90% vs. 50%) power conversion efficiency.

The user is typically responsible for engineering the linear motion system, which often includes purchasing the actuator, motor, gear reducer,  timing belt  mounting, flexible couplings, etc. separately, and then assembling these components so that they perform properly in the given application. The GS actuator eliminates the  need for this systems engineering. The elements for producing linear motion have been properly matched and designed into the actuator and  tested for efficiency, smoothness, accuracy, rigidity and reliability. All this is accomplished in a much  smaller package than traditional  rotary-to-linear conversion mechanisms.
