Aerotech MPS95LZS Low-Profile Z Linear Motor Stages

MPS-LZS stages define a new benchmark for high-quality vertical motion

that breaks the traditional tradeoff between precision and price.

For demanding applications that require a careful balance of performance

and cost, you no longer have to compromise on core technology.

MPS95LZS stages feature anti-creep, crossed-roller bearings; ironless linear

motors with exceptionally high force density; and an adjustable pneumatic

counterbalance to offset up to 4 kg payload – so you get smooth, precise

motion. Plus, MPS-LZS stages are form-factor compatible with our industry

-leading ANT-LZS vertical nanopositioning stages, giving OEMs an easy and

efficient means to scale.

Noncontact Direct-Drive Technology

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

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

Compared to traditional screw-driven vertical and lift stages, MPS-LZS stages

can move and accelerate faster and more precisely. This is because MPS-LZS

stages use an ironless linear motor that eliminates cogging effects that would

otherwise cause position errors and disturbances. Coupled with anti-creep,

crossed-roller bearings, MPS-LZS delivers smooth, consistent vertical 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-LZS 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-LZS 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 extreme

performance and cost effectiveness.

Integrated Counterbalance

MPS-LZS stages are equipped with a minimally influencing pneumatic

counterbalance to offset the gravitational forces from the carriage and payload.

It includes a precision regulator for the exact dialing-in of the counterbalancing

force. Unlike spring or magnetic counterbalance designs, the pneumatic

counterbalance can be easily adjusted to exactly offs

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.
