The IMS-LM series linear motor stages are designed for self-supporting applications with travel ranges from 300 mm to 1200 mm. The stages feature a robust design with highperformance but with low cost, making them cost-effective solutions for precision industrial applications such as semiconductor wafer inspection, micro-electronics test andassembly, pick and place, DNA sequencing, or laser machining. The IMS-LM-SA version with, 4-pt mounting, is ideal for delay lines and other applications with non-flat mountingsurfaces.The IMS-LM series utilizes an FEM optimized aluminum extruded body that is extremely stiff and minimizes the bending effect caused by different thermal expansion coefficientsof the aluminum body and the steel rails. Unlike-screw driven stages, the IMS-LM employs a center-driven linear motor. This linear motor is absolutely noise-free and has the advantage of higher speed, acceleration and system responsiveness with no wear of motor brushes or drive screws. Due to the fully integrated linear motor, the IMS-LM is more than 100 mm shorter in length than a comparable screw driven stage. Thus, the IMS-LM is the optimum solution for space constrained applications that require high-throughput, high reliability, and ultra-quiet operation.The IMS-LM uses a high efficiency 3-phase synchronous ironcore linear motor. While ironcore linear motors are often criticized for their cogging and high attractive forces, theirefficiency is almost twice the efficiency of ironless linear motors. This results in higher acceleration capabilities and significant less heat dissipation which often limitsperformance of rapid point-to-point positioning.Recirculating ball bearing slides with caged balls provide excellent payload capacity and long life. The ball separators in the recirculating elements ensure superior smoothmovement, lower noise, and longer service life compared to uncaged ball bearing slides. Precision position feedback is supplied by a highly repeatable linear scale mounted inside the stage. The encoder signals are interpolated by Newports XPS motion controller with20 nm MIM for outstanding Minimum Incremental Motion, repeatability, and stability. Absolute home position and limit signals are incorporated in the same to improverepeatability and reliability, while simplifying the design with less electronics and mechanical parts.
For critical positioning applications, Newport offers micropositioning calibration services. We will create, implement and verify an electronic compensation process to improve the absolute position accuracy of your Newport IMS-LM Series stages when commanded by our XPS advanced motion control system. Compensation is performed at 20.0 °C, +/-0.2 °C, for linear and non-linear errors, ensuring accuracy of up to 1 µm + 1 µm/100 mm over center 80% of travel. A certificate of calibration per Newport Metrology Procedure A167 and measured error maps are provided. Click here for complete information.
