Micro Linear Actuators
M3-L MICRO LINEAR ACTUATOR WITH EMBEDDED CONTROLLER
The M3-L is a miniature high-resolution positioning system. It is a “smart” actuator with integrated driver and closed-loop controller inside the actuator.
This compact, powerful motion system helps OEM designers improve performance and reduce the size of instruments in a wide range of applications.
M3-L micro linear actuators add high-resolution positioning to portable and hand-held devices. They accept a 3.3 V supply and high-level input via standard serial interface.
NOTE: Actuator vs. Translation Stage
The M3-L is a linear actuator designed to push or pull a light object. It requires careful attention to loading under static and dynamic conditions. It is not designed to carry a load. If you need to carry a load, please consider the M3-LS Linear Smart Stage instead.
- Small: complete, compact system with embedded closed-loop controls. Less than half the size and one-fourth the weight of comparable systems.
- NO external control board is needed.
- Precise: 0.5μm position resolution with six millimeters of travel.
- Low voltage, low power use: runs on 3.3V input, holds position with power off.
- Simple system integration: accepts high-level motion commands DIRECTLY from your system processor, over standard serial interface (I2C or SPI).
- Flexible system, fast time to market: the M3 platform is designed for rapid customization. Modules are configurable for single- or multi-axis motion and travel up to 20 mm.
The M3-L is ideal for precision tuning of optical and photonics systems. Defense applications include laser beam steering and targeting, UAV and UGV flight controls, and field-portable systems for biomedical and chemical detection and analysis. Medical applications include micro surgical devices and point-of-care systems.

The M3-L micro linear actuator has an integrated SQUIGGLE motor and controller inside the compact housing. The motor moves a mechanical assembly. The NSE-5310 position sensor detects the movement of a multi-pole magnetic strip attached to the moving mechanical assembly, and provides the direct digital position information to the motion control processor.
The on-board NSD motor drive ASIC accepts commands from the processor and drives the motor. System input is provided as high-level commands from the system microprocessor via standard I2C or SPI serial interface. NO EXTERNAL CONTROL BOARD IS NEEDED. The M3-L linear actuator operates on standard 3.3 V battery power.
