Ultra-Compact Piezoelectric XYZ Stage for Precision Motion
Key Advantages of LRMO-XYZ System
- Compact light weight design (just 1″ x 1″ x 1.8″)
- Superior Resolution: > 40 nm = 25,000 steps per mm of linear travel with 9.0 mm of Travel per Axis
- Max Speed: ≈0.15 m/s
- Fast Response Time: ≈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 each with 9.0 mm of travel (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.
