The EDGE Motor from Nanomotion is a micro sized sub-micron resolution ceramic servo motor that provides extremely compact positioning for space-restricted and miniaturised mechatronic assemblies.
Available in the UK from Heason Technology, a precision motion specialist, the EDGE measures just 13.5mm long, 7.6mm wide and 3.15mm high; yet has the power to deliver a dynamic stall force of 300mN at speeds of up to 120mm/sec -sufficient to position apertures, shutters, focusing 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 1.35mm 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 -20ºC to + 60ºC 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.
