Specialty Motion Stages
stages in the world.
Piezo Motor Company’s Specialty Motion Stages deliver sub-micron precision in ultra-compact form factors that conventional motor technologies simply cannot achieve.
Engineered for researchers, instrument designers, and OEM integrators who refuse to compromise between size and performance, our LRMO-XYZ and ROMO-3AX platforms establish a new benchmark in miniaturized multi-axis motion.
Built on PMC’s patented piezoelectric actuator technology, these systems provide exceptional precision, stability, and control—all within packages compact enough for the most space-constrained environments.
Whether your application requires nanometer-scale linear positioning across three axes or precise multi-axis rotary motion, PMC’s Specialty Motion Stages are designed to integrate seamlessly into next-generation instruments and embedded systems.
Specialty Motion
Stages
Resolution
Linear steps down to <40 nm (LRMO-XYZ) and angular steps as fine as 30 µrad (ROMO-3AX), enabling nanometer and micro-radian level repeatability.
Backlash
by Design
Maintains position with zero power consumption. No active current is required to hold position.
Operation
Operation
Operates at low DC voltages (typically 5 V), making it ideal for battery-powered and thermally sensitive applications.
Ready
Optional encoder configurations enable nanometer and micro-radian level closed-loop control for the most demanding applications.
Integration
Pre-programmed driver PCBs with PWM, UART, and I²C interfaces allow fast deployment, simple control, and seamless software integration.
