Nanomotion’s Miniature EDGE Motor for Space Critical Precision Positioning
Date: 29 August 2008
New Ceramic Servo motor module is rated as the smallest industrial motor of its kind
The EDGE Motor from Nanomotion is a micro sized
sub-micron resolution ceramic servo motor that provides an
extremely compact positioning solution for space restricted and
miniaturised mechatronic assemblies.
Available in the UK from Heason Technology Limited, the leading
precision motion specialists, the EDGE measures just 13.5 mm long,
7.6 mm wide and 3.15 mm high yet has the power to deliver a dynamic
stall force of 300 mN at speeds of up to 120 mm/sec - sufficient to
position apertures, shutters, focussing mechanisms and other small
optical devices as well as miniature pumps, grippers and
micro-positioning actuators with unlimited linear or rotary
travel.
The EDGE Motor's modular design includes a flexible flat vinyl
cable assembly with two 1.35 mm diameter mounting holes and
mounting pins for simple integration into a suitable bearing
structure with linear encoder or other position feedback device.
The durable motor is rated for industrial applications with a
temperature range of - 20 to + 60 oC and is well suited
to non magnetic environments.
Servo motor control is provided via a compact ASIC-based driver
which is compatible with Nanomotion motion controllers and most
analogue interfaced (+/- 10 V) motion controllers from Heason
Technology's wide range. Servo motion is guaranteed both smooth and
precise over a wide dynamic velocity range with positioning
resolution better than 100 nanometres, making the EDGE motor
suitable for ultra-low speed scanning appplications.
Unlike standard rotary micro motors, the technology has a unique
inherent holding force, effectively braking and maintaining motor
position at standstill and under power-off conditions - with
complete stability and zero drift.
