Welcome to New Scale News, your monthly update on micro-mechatronic systems and applications. This month we answer your questions about M3 module position resolution, share a customer application, and close with a short video holiday greeting.
M3 micromechatronic modules: closed-loop vs. open-loop stepping and position resolution
M3 beam steering system
New Scale M3 micromechatronic modules are "all in-one" smart modules, with the controller and position sensor built in to the miniature module. This embedded closed-loop control gives you the smallest size, fastest and simplest integration into your system, and lowest total cost.
When the application requires, M3 Smart Modules can also move using open-loop commands from the SPI, I2C or UART interface. This is particularly useful in applications that have an external sensor with better resolution than the internal sensor, or where very fast "step and settle" performance is required.
For example, for the M3-RS-U Rotary Smart Stage in the beam steering developers' kit, the closed-loop stepping resolution is 0.025 degrees (440 microradians) and accuracy is 0.25 degrees (4400 microradians), limited by the resolution of the embedded absolute angle sensor in the module.
Used open-loop, the stage has a resolution of better than 0.0057 degrees (100 microradians) and accuracy is typically better than 10% of the distance traveled after calibration. Read more.
Crest Optics is using the M3-LS Smart Stage multi-axis positioning system to enhance the resolution of optical flourescence microscopes. They gave us four key reasons for choosing the M3-LS:
Very compact size, easy to fit in our system
Very smart software developer's kit (SDK) package with compact electronics for the first phase of devolpment
Very competitive price
Electronic and software interface suitable for fast integration
