Dover's Mini-MAG Linear Servo Driven Stages Available from Heason
Date: 01 August 2010
Dover's recently introduced Mini-MAG high precision linear servomotor stages are available from motion specialists, Heason Technology.
The compact 80 mm wide all-stainless steel
stages use Dover's well proven and unique MAGT moving magnet
concept that eliminates moving motor cables and are factory stocked
for fast delivery in four standard travel ranges from 25 mm to 150
mm.
With overall accuracy to 3.0 µm, positioning resolution to 5.0 nm
and bi-directional repeatability to +/- 200 nm, the powerful
3-phase brushless linear servomotor facilitates an impressive speed
rating of 500 mm/sec with 9 g acceleration, making the Mini-MAG
equally suited to high speed step & repeat or constant velocity
scanning - for exacting and rapid throughput micropositioning
applications in production or test.
The Mini-MAG features precision cross roller bearings with
anti-creep cages which ensures zero readjustment downtime and the
negligible bearing friction allows excellent in-position servo
system stability. The durable cross roller bearing set and
high-stiffness stainless steel construction combine for a direct
load rating of up to 8 kg.
A side mounted tape-style linear encoder with a non-contacting
reading head provides high resolution analogue or digital position
feedback plus datum and adjustable limit switch functions in a very
compact envelope and convenient design which is easily integrated
with the servo drive and motion system. Resolution options include
0.1 ?m, 0.05 ?m, , 0.02 ?m, 0.01 ?m and 0.005 ?m. The fixed reading
head also ensures no moving cables on single axis stages.
The Mini-MAG's moving top plate includes a series of M8 holes for
customer fixtures and provision for direct X-Y mounting with no
adapter plates. The range includes a standard counterbalanced
version for vertically mounted positioning.
In addition to fast delivery times the Mini-MAG also offers almost
twice the accuracy at around the same cost of competitive standard
grade stage options from other manufacturers. With its high
precision, impressive dynamic performance, smooth servo motor and
non-contacting encoder, the stage will provide a long-life, low
maintenance and excellent positioning solution across a wide range
of manufacturing and research applications.
Heason Technology supply the Mini-MAG with complementary servo
drives and motion controls as a part of its comprehensive motion
control service that includes an in-house design capability that
matches products from its distribution partners for customised
electro-mechanical solutions in challenging applications across,
aerospace, automotive, defence, robotics, process control,
packaging, motorsports and many more.
