Motorized Vertical Stage, 300 mm Travel, 400 N Load, DC motor, 1/4-20

Similar to the finite element method (FEM) used to optimize the structural design of IMS series DC and stepper motor linear stages, the optimized aluminum body of the IMS-V is designed for extreme stiffness and minimizes bi-metal bending without compromising weight. This results in a light and stable stage whose rigid body reduces deflection under load.

The IMS-V features four-point contact, recirculating ball bearings to provide superior cantilevered loading capacity compared to other vertical stage families. The caged, recirculating ball bearings counteract moment loads and ensure maintenance-free operation.

Precision position feedback is provided by a linear scale encoder, which contributes to sub-micron MIM and makes the IMS-V less susceptible to hysteresis. The direct read system is impervious to position drift caused by motion-induced heating of the lead screw for improved accuracy and repeatability.

The drive system utilizes a self-locking lead screw with a proprietary, low-friction and wear-resistant nut optimized for carrying high axial loads. Consequently, these features decrease settling time by minimizing oscillation and unwanted motion. Additionally, the self-locking lead screw is not back drivable. This offers the best position stability, and (in contrast to braked ball screw drives) when the stage is within proper loading conditons, its position will not change when power is off.

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.
