Precision linear motor stages


Dover, a Danaher Motion company, has introduced the MMG Mini-Mag line of precision linear motor stages.  Mini-Mag Stages deliver nearly twice the accuracy at virtually the same cost as competitive standard-grade options. The ability to deliver MMG prototypes rapidly speeds the proof-of-concept phase of an instrument under development, the company says.

Four models are available that deliver 25, 50, 100 and 150-mm travel, respectively.  They provide uncompensated accuracy ranging from 2um to 8um and resolution ranging from 1.0 um to 5 nm. Each model delivers repeatability to ±0.4 um and is rated for 8 kg load capacity.

One of the most significant features is an Integral anti-creep linear guideway, which can increase uptime by as much as 15 percent in high duty cycle applications by eliminating the need for homing moves typically required to reset standard crossed roller bearing retainer cages. These stages also feature adjustable limits to reduce the time needed to make adjustments to stage travel, thus reducing prototype development time and system startup costs by up to 10%.

An integrated advanced feedback mechanism enables exceptional uncompensated accuracy.  This encoder eliminates the need for compensation tables or slope correction factors, thus lowering software and integration complexity and implementation time.  A standard “Z” axis counterbalance kit eliminates the typical engineering required to integrate a “Z” option, thus reducing the implementation time of a “Z” axis stage.
