New Scale Technologies Inc.'sminiature M3-L closed-loop linear motion module has a 0.5 micron positionresolution and a total package size of less than 27.5 x 13 x 7.5 mm. All motionand control functions are fully integrated into the M3-L module, including apiezoelectric linear micro motor, position sensor, guide mechanism, motordriver, control processor and software. The module runs on 3.3V input forbattery-powered operation. The standard serial interface (I2C or SPI) acceptsPID closed-loop system tuning parameters, as well as high-level input commandssuch as "move specified distance." No external controller isneeded.

TheM3-L module is offered with a bullet nose for pushing or a hook tip for pullingloads. Typical travel range is 6 mm. New Scale also develops custom OEM modulesincluding bi-directional (push/pull) systems, modules with custom travel rangeup to 20 mm and multi-axis configurations.

TheM3-L module draws approximately 500 mW of power while moving and 200 mWquiescent. Weight is approximately 4.5 grams without tips. M3-L productionmodules are customized to OEM specifications. M3-L Developer's Kits include anM3-L linear module along with a USB key and New Scale Pathway PC software. Thisgives designers a graphical user interface to evaluate motion and a scriptingenvironment for system development.

Itis useful for precision motion control of variable inductors, trimmingcapacitors and optical elements for RF, microwave and photonics tuningapplications. It also adds motion to a wide range of miniature optical andhand-held instruments, aerospace and UAV controls and biomedical systemsincluding fluid controls and microsurgery.
