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 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.
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 28 N and measuring just 41.6 mm x 46.6 mm x 23.8 mm (l x w x h) with a mass of only 120 g.
Nanomotion’s ceramic servomotors provide an effectively unlimited travel range, a nanometre level resolution and speeds ranging from 1 μm to 250 mm 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 feed-back is required for servo positioning applications although ceramic motors may be used in open loop mode for standard actuator type applications. Dedicated 20 kHz servo drives can be supplied from Nanomotion and Heason also offer other compatible drives along with range of motion controllers.
