Aerotech MPS95LM Single-Axis Miniature Linear Motor Stage

The New Standard for Value-Driven Precision

MPS-LM stages define a new benchmark for high-quality linear motion

that breaks the traditional tradeoff between precision and price. This

makes them the ideal solution for demanding applications that require

a careful balance of performance and cost, without forcing you to

compromise on core technology. MPS-LM stages feature anti-creep,

crossed-roller bearings and ironless linear motors with exceptionally

high force density, resulting in smooth, precise motion. Plus, MPS-LM

stages are form-factor compatible with our industry-leading ANT-L

family of nanopositioning stages—offering OEMs an easy and efficient

means to scale.

Reduce Output-Switching Noise

The MFM Motor Filter Module reduces conducted line noise

generated by pulse width modulation (PWM)-switching servo

amplifiers. Use the MFM with our Automation1 XC4e, XC2e,

XC4 and XC2 servo motor drives.

The Enhanced Throughput Module (ETM) improves the positioning

performance of high-dynamic motion systems by directly measuring

the unwanted motion of the machine base and communicating it back

to the controller. By working in concert with the Dynamic Controls

Toolbox and the Aerotech controllers, ETM allows the servo system to

do a superior job of executing the desired motion path.

Noncontact Direct-Drive Technology

Only noncontact direct-drive technology offers the robust, accurate and

high-speed positioning necessary for mass production of precision devices.

MPS-LM stages use our advanced direct-drive technology to achieve superior

positioning performance. An ironless linear motor eliminates motor cogging

effects that would otherwise cause position errors and disturbances.

Coupled with anti-creep, crossed-roller bearings, MPS-LM delivers smooth,

consistent motion with outstanding dynamic characteristics to enhance your

process capability at an attractive price point. The optimized drive and bearing

combination, packaged in a compact form factor, offers distinct performance

advantages in many applications such as high-precision positioning, fiber

alignment, optics manufacturing and inspection, sensor testing and scanning

processes that demand smooth and precise motion.

Flexible System Design

MPS-LM stages feature convenient mounting patterns in the base and tabletop

to allow for easy system integration. Multiple stages can be assembled together

for flexible system designs and application-specific, multi-axis configuration.

Because MPS-LM stages are form-factor, drop-in compatible with our industry-

leading family of ANT nanopositioners, you can effortlessly combine MPS-LM

and ANT stages into multi-axis systems to achieve a balance of nanometer-level

performance and cost effectiveness.

High Precision ER Collet

The collet chuck on the ACS 100LP accepts an ER8 series collet, while

the ACS 150LP uses an ER25 collet and the ACS 200LP uses an ER40

collet. These collets are readily available from machine tool component

suppliers in sizes that support tube diameters from 0.5 mm to 30 mm.

ER collets provide excellent run-out characteristics for applications 

requiring high-precision gripping of tubular material. The collet is

retained with a threaded retaining nut that enables quick changeover,

and is configured in a “fail-safe” normally-closed mode where full

clamping force is applied when no air pressure is present.

Compact Package

The design of the ACS LP series direct-drive rotary stage was optimized

to minimize stage height. The low profile of the stage reduces the effective

working height of the system minimizing “stack-up” related errors.

Integral Rotary Union

Air is delivered to the collet or gripper assembly through an integral rotary

union using a seal-less, frictionless design. This 100% noncontact rotary-

union design ensures a lifetime of maintenance-free operation.

The combination collet chuck and rotary union assembly also has significantly

less friction and inertia than external assemblies created from discrete parts.

This reduced inertia improves system performance by allowing higher peak

acceleration and reducing position error during laser machining operations.
