New Scale Technologies (Victor, NY) has introduced the miniature M3-L closed-loop linear motion module, featuring 0.5 micron position resolution and a total package size of less than 27.5 × 13 × 7.5 mm. It is suitable for applications in fluidics and valve controls, microsurgical manipulation, and precision photonics and optical controls in a diverse array of biomedical products such as lab instrumentation, portable medical devices, and endoscopic surgical devices. Motion and control functions are fully integrated into the module, including a piezoelectric linear micro motor, position sensor, guide mechanism, motor driver, control processor, and software. The module runs on 3.3 V input for battery-powered operation. The standard serial interface (I2C or SPI) accepts PID closed-loop system tuning parameters, as well as high-level input commands such as “move specified distance.”
