Engineering isn’t a one-size-fits-all proposition. We can customize nearly everything we sell, from modifying housings and mechanical interfaces to fine-tuning performance parameters. Interested in custom assemblies?



Z-AxisnPL70 Linear-Motor Stage 

Designed and manufactured by Motion Solutions, the nPL70 linear-motor stage (MSL) is an integrated actuator aimed at life sciences, medical, and semiconductor OEMs. The stages are available in vertical, horizontal, and multi-axes configurations. They incorporate ironless linear motors for smoothest possible motion and minimal velocity error. Even without the iron core, the motors still operate with very high force density, courtesy of a patented coil design.

nPL70 stages feature cross-roller bearings with anti-cage-creep technology. These components, combined with precision preloads, result In high stiffness and smooth, accurate motion. The stages are designed with a high natural frequency (high-bandwidth) for low settling times.

Applications include microscopy, sample positioning, and imaging. Other examples include light- to medium-duty applications such as photonic and fiber-optic manufacturing.
