The ILS 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 provide 50-250 mm of travel and are capable of high-duty cycles in light industrial applications. Stepper motors are a lower cost alternative to DC servo systems for less demanding applications. These stages feature micro-stepping and a screw-mounted rotary encoder to improve resolution and smoothness of motion.

Features
Economical Micro-stepping Stepper Motor
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.
FEM Optimized Aluminum Body
Finite element method (FEM) was used to optimize the structural design of the ILS 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 IMS stages are also available which offer longer travel ranges, higher load capacities, and larger moving platforms.
Rotary Encoder for Improved Performance
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.

ILS Stage Motor Options
ILS Series stages are available with the following motors:
- Stepper Motor (ILS-BPP) - For less demanding applications, a stepper motor can be a more economical solution than a DC motor.
- High-torque DC motor (ILS-CC) - Best characterized by their high speeds, smooth motion, good efficiency and a high power/weight ratio, DC motors are preferable to stepper motor stages for applications requiring high dynamic speed and tight repeatability.
- Linear Motor (ILS-LM) - The ILS-LM employs a centered, high efficiency 3-phase, synchronous ironless, linear motor. This drive system is noise-free and provides higher speed, acceleration and system responsiveness without the wear associated with motor brushes or drive screws.
