IMS-V Series High-Load Vertical Linear Stages

Product catalog summary

Specifications:
The document provides technical specifications for the IMS100V and IMS300V motorized linear stages. Key specifications include travel ranges of 100 mm and 300 mm, respectively, with minimum incremental motion of 0.3 µm using XPS controllers. Uni-directional repeatability is 0.2 µm, and on-axis accuracy ranges from 1.5 µm to 10 µm depending on the model. Maximum speed is 20 mm/s with up to 100 N load. The stages have a mean time between failures (MTBF) of 20,000 hours under specified conditions.

Design Details:
The IMS-V series features a high-load vertical linear stage design with an extruded aluminum body optimized for stiffness and minimal thermal bending. It uses four-way equal load rating ball bearings and a self-locking lead screw for stability. The drive mechanism includes a precision ground lead screw with a high-wear resistance nut, and direct position feedback is provided by a linear steel scale with 0.1 µm resolution.

Load Characteristics and Stiffness:
The stages support a maximum load of 500 N with XPS controllers and 100 N with ESP300 or SMC100CC controllers. Compliance in pitch and yaw is specified as 0.2 µrad/N.m and 1 µrad/N.m, respectively.

Ordering Information:
Models available include IMS100V and IMS300V, with recommended motion controllers being XPS, ESP300, and SMC100CC, each supporting different payload capacities and minimum incremental motions.

Dimensions:
Detailed dimensions for the IMS100V and IMS300V models are provided, including thread dimensions and top plate interface specifications.

Using the same industry-proven technology as the IMS stages, the IMS-V stages provide very high performance in a cost-effective package, making them ideal solutions for precision industrial and laboratory applications. All IMS-V series stages are optimized for maximum stability and performance using FEM analysis, resulting in a light and stable stage. While high in stiffness, the bending effect caused by different thermal expansion coefficients of the aluminum body and the steel rails is also minimized. Four-way equal load rating ball bearings provide superior support for high cantilevered loads, and the caged recirculating balls ensure maintenancefree operation without cage migration. The drive system utilizes a 16 mm diameter lead screw with a proprietary wear resistant polyethylene terephthalate nut Design Details Base Material Extruded Aluminum Bearings Four way equal loaded caged recirculating ball bearings Drive Mechanism Precision ground 16 mm diameter lead screw, High-wear resistance polyethylene terephthalate nut, no preload Drive Screw Pitch (mm) 3 Feedback Linear steel scale, 20 ìm signal period, 0.1 ìm resolution Limit Switches Optical Origin Optical, approx. 8 mm from motor side limit Motor DC servo motor UET511 Cable 5 m long motor cable included optimized for carrying high axial loads. The drive nut closely assimilates static and dynamic friction, minimizing the slip-stick effect found in classical lead screw systems. When used with our XPS motion controller, this guarantees better than 300 nm motion sensitivity, even at full load and over the life of the stage. The lead screw self locks to ensure superior in-position stability with no change of position at removal of power – something typically experienced with braked ball screw drives. Precision position feedback is supplied by a linear scale with 0.1 ìm resolution. This direct optical reading system provides superior accuracy and minimum hysteresis when compared to indirect feedback systems. The direct read system is impervious to position drift caused by motion-induced heating of the lead screw for improved accuracy and repeatability.
