DuraMotor Extends Durability Performance For UHV Applications
Date: 02 April 2007
Nanomotion's new DuraMotor ceramic servo motor extends durability performance for demanding ultra-high precision motion applications...
New and improved materials provide
exceptional cleanliness and improve motor life.
Nanomotion's new DuraMotor series ceramic servomotors provide
superior levels of durability for sub-micron linear and rotary
positioning applications in high vacuum, clean room and non
magnetic environments and for demanding high-duty/high speed move
and settle motion profiles.
Based upon Nanomotion's unique standing wave inverse piezoelectric
effect technology, the DuraMotor benefits from new materials and
manufacturing techniques for the motor tip and drive strip to
provide exceptionally low wear characteristics and long life
capability. The new range will suit demanding production and test
applications in semiconductors, fibre optics, photonics,
electronics, MEMS, bio-medical and cutting-edge research.
Available in the UK from Heason Technologies, the new DuraMotor
series includes four versions with 1-, 2-, 4- and 8- element motors
in a choice of configurations covering standard, vacuum, ultra high
vacuum, non magnetic and combinations of vacuum plus non-magnetic.
The range is identical to Nanomotion's HR series with the 8-element
version producing a static holding force of 28N and measuring just
41.6mm x 46.6mm x 23.8mm (l x w x h) with a mass of only
120g.
Nanomotion's ceramic servomotors provide an effectively unlimited
travel range, a nanometre level resolution and speeds ranging from
1?m to 250mm per second with exceptional smoothness, fast settling
times and excellent in-position stability. Depending upon the
loading and inertial requirements of the application, single or
multiple motors transmit force on to a drive strip which is fixed
to linear or rotary stage mechanics. The motors also provide a
built-in braking and holding capability and may be used with cross
roller, linear motion guide or air bearing based precision
positioning stages.
Encoder or other precision feedback is required for servo
positioning applications although ceramic motors may be used in
open loop mode for standard actuator type applications. Dedicated
20kHz servo drives can be supplied from Nanomotion and Heason also
offer other compatible drives along with range of motion
controllers.
The extremely compact motor design lends itself to customised
applications where envelope space is irregular or limited. Ceramic
servomotors bring advantages in size, simplicity, force per volume,
dynamic performance and cost over traditional drive
technologies.
