LRMO-XYZ

Ultra-Compact Piezoelectric XYZ Stage

Introducing the LRMO-XYZ the world’s smallest lightweight piezoelectric XYZ platform designed for superior precision and expanded functionality for advanced applications.

Key Advantages of LRMO-XYZ System

Compact light weight design
Superior Resolution: > 40 nm = 25,000 steps per mm of linear travel with 9 mm of travel per axis
Max Speed: ca. 0,15 m/s
Fast Response Time: ca. 30 µs
Low Voltage Design: 5 V DC
Zero power consumption in hold mode
Optical encoder (optional): 2,66 µm close loop resolution

Design Principle

The LRMO-XYZ system integrates three precision miniature linear piezomotors (PMC Model# LRMO) into a compact XYZ stage, providing precise multi-axis motion in an ultra-small footprint. It is ideal for space-limited applications where silent operation, zero backlash, and sub-micron resolution are required. The LRMO-XYZ offers reliable, high-precision XYZ motion control for delicate applications where traditional XYZ designs are too bulky, heavy or generate electromagnetic interference, making it ideal for next-generation motion solutions in optics, life sciences, and precision instrumentation.

Electronic Driver Supports UART & I2C

The electronic driver is designed to offer an economical interface for user control. Motion of the motor is achieved via PWM (Pulse Width Modulation) control signals. The driver PCB also supports UART and I2C interfaces. The driver PCB is pre-programmed for software configurability, optimizing drive signals and integrating controls. Motor operation can be finely regulated through closed-loop control using an optional encoder factory-installed on the actuator.
