A fully integrated NEMA 11 microstepping motor

With a 28mm square housing and length of just over 70mm for the triple stack motor version, capable of a 0.17Nm stall torque, the DMX-K-SA-11 is the smallest industry package for a distributed motor, driver, controller and encoder available today - and is delivered as a plug-and-play package with free-of-charge motion programming and set-up software.

A recent application for a film camera equipment manufacturer allowed the installation of the tiny DMX-K-SA-11 package to drive and position a miniature video camera that required precise run and repeat motion sequences in very confined spaces.

In another application a multispectral digital still camera lens system that rotates interchangeable colour-transparent screens for use in forensics, biological identification and many other life science areas (pictured) was developed with the NEMA size 11 package for commercial use.

The DMX-K-SA-11 features RS485 communication and opto-isolated limit and home inputs which may be configured as general purpose outputs together with a single digital output. The BASIC-like programming language simplifies high resolution position control with up to 1/16 microstepping in combination with an integrated 256 line incremental encoder. An absolute encoder is available as an upgrade. The drive is configurable for 12 to 24Vdc operation and selectable current from 100mA to 1.5A.

Also available are NEMA 17 and 23 frame size versions of the DMX-K-SA offering increased voltage and current with additional digital I/O that may be used for high speed position capture and event synchronisation.
