Newport¡¦s UTS series linear stages incorporate many of the advantages of the popular UTM series providing superior motion performance in an enhanced, shorter, and lower profile package. They use the same optimized steel body, bearings manufacturers and lead screw of the UTM stages, but feature a number of mechanical improvements and completely new motor configurations.
UTS linear stages are available in three configurations. The first version, utilizing a Dc motor specification, features an ultra-high resolution 20,000 cts/rev rotary encoder with index pulse for precision homing and is the recommended choice for applications requiring accurate bi-directional positioning. For tightest position control, the rotary encoder is directly mounted on the lead screw. This eliminates the majority of drive train error sources that affect other stages with indirect position read-out. A high-torque DC motor provides the highest dynamic speed control and allows for linear speeds up to 40 mm/s. An 11:4 belt reduction between the motor and the lead screw increases the available output torque, reduces the servo sensitivity and ensures 0.3 ƒÝm incremental motion capability with all Newport manufacturers of motion controllers and drivers.
The stepper motor manufacturer version is a cost-effective solution for less demanding applications. When used with our XPS, ESP300, or SMC100PP controllers with high micro-stepping capability, low-noise operation and very small incremental motions are guaranteed. The stepper motor versions do not use industrial encoders, instead, position is attained by the number of commanded steps and micro-steps.
