The Edge motor can deliver a dynamic stall force of 300mN at speeds of up to 120mm/s, sufficient to position apertures, shutters, focussing mechanisms and other small optical devices
Nanomotion's Edge motor is a micro-sized, submicron-resolution ceramic servomotor that provides an extremely compact positioning solution for space-restricted and miniaturised mechatronic assemblies.
Available in the UK from Heason Technology, the Edge measures 13.5 x 7.6 x 3.15mm but can deliver a dynamic stall force of 300mN at speeds of up to 120mm/s, 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 1.35mm 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 - 20 to +60C and is well suited to nonmagnetic environments.
Servomotor control is provided via a compact ASIC-based driver which is compatible with Nanomotion motion controllers and most analogue interfaced (+/-10V) motion controllers from Heason Technology's range.
Servo motion is both smooth and precise over a wide dynamic velocity range, with positioning resolution better than 100nm, making the Edge motor suitable for ultra-low speed scanning applications.
Unlike standard rotary micro motors, the technology has a inherent holding force, effectively braking and maintaining motor position at standstill and under power-off conditions with complete stability and zero drift.
