Nanomotion's miniature EDGE Motor for space critical precision positioning is available from Heason Technology

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.
