- M3 Modules and Closed-Loop vs. Open-Loop Stepping
M3 micro-mechatronics 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.
- Micro beam steering solutions
New Scale’s miniature M3 beam steering modules are designed for precise point-to-point positioning and dynamic movements up to 1K Hz. The direct-drive piezoelectric motors inside the modules hold position with zero power and no servo jitter. The effects of external vibrations on the mirror position are highly damped. M3 smart modules have fully-integrated closed loop controllers and communicate directly with your system processor over a standard serial interface. They have low drive voltage and low power use, making them ideal for portable instruments. This tech bulletin describes three types of beam steering solutions: a two-mirror system with galvo-type motion, a single-mirror solution with a tilting around a central pivot, and a dual-wedge Risley device.
