The IMS Series is a robust line of fast, sub-micron resolution linear stages constructed with a light, stiff aluminum body and reliable components that prevent thermal bending effects. They complement the ILS Series linear stages by providing longer travel ranging from 300-600 mm and are capable of high-duty cycles in industrial and laboratory applications. Stepper motors are a lower cost alternative to DC servo systems for less demanding applications. These stages feature micro-stepping and screw-mounted rotary encoder to improve resolution and smoothness of motion.

Finite element method (FEM) was used to optimize the structural design of the IMS Series stage aluminum body allowing for extreme stiffness and minimizing bi-metal bending without compromising weight. The rigid body design reduces deflection under load allowing for the highest performance possible in an aluminum stage design. FEM optimized ILS stages are also available which offer shorter travel ranges, lower load capacities, and smaller moving platforms.
For less demanding applications, a stepper motor can be a more economical solution than a DC motor. A stepper motor operates using the basic principle of magnetic attraction and repulsion, converting digital pulses into mechanical shaft rotation. To improve the resolution and smoothness of motion, these stages feature micro-stepping, a method of electronically dividing a full-step of motion into a high number of partial steps.
Stepper motors are often run open-loop, with position attained by the number of commanded steps and micro-steps. This works reliably when used within their specified torque and speed range; however, the motion of a stepper motor becomes unpredictable outside their specified range. To avoid screw/motor coupling errors, position measurements of these stages are read on a 4000 cts/rev. rotary encoder located directly on the screw.
The recirculating ball bearing slides provide excellent payload capabilities and longer life with accurate linear trajectory. It mitigates the issue of ball cage migration, which is typically found on linear ball bearings or crossed roller bearings.
These motorized linear stages include a preloaded, backlash-free, precision ground ball screw, which provides smooth, rapid motion with short step and settling time. The screw profile is designed to reduce heating effects, extending the life of the stage.
A rigid top cover prevents damage to the drive train and protects it from dust and debris. IMS Series stages also feature a motor-end mounted origin for repeatable initialization, limit switches to prevent over travel, and elastomeric end-of-run dampers for smooth emergency braking.
Newport guarantees specification values which are measured and recorded following ASME B5.57 and ISO 230-2 standards. The typical performance values are two times better than the guaranteed specifications.
