Redundant precision linear actuator with a volume less than four cubic centimeters
A global aerospace and security company required a new and highly miniaturized M3 smart motion module. We used custom SQUIGGLE motors with higher force to create a linear positioning module that moves a precise distance (hundreds of micrometers).
A unique challenge was providing fail-safe redundancy of the "OFF" position by integrating two motors that work together in a unique spring and slide mechanism, operated by duplicate drive and control electronics.
New linear actuator for real-time engine tuning
A
first-tier automotive component supplier needed a
highly miniaturized linear actuator with very high holding force (hundreds of Newtons) when not powered, and also a range of several millimeters.
- Achieving a simple and manufacturable design.
- Minimizing operating power.
- Operating reliably in the extreme environment of a car engine.
Tiny motorized focus module for advanced imaging
A leading medical equipment company
required micrometer-scale lens movements in a highly restricted space of less than one cubic centimeter.
New Scale's experience with the M3-F and M3-FS Focus Modules and also the tiny UTAF motor was the starting point for creating this unique mechanism. Dual UTAF motors and flexure guides work together to generate precise linear movement with minimal tilt and de-centering.
Miniature high-force linear actuators in multi-axis systems
An emerging computer device company needed ti
ny actuator systems with several Newtons of force to provide real-time movements over many millimeters.
The M3-LS-1.8-6 Linear Smart Stage was the starting point for this custom development project. A new, higher-force SQUIGGLE motor was created and integrated in a highly miniaturized X-Y stage less than 20 X 20 X 10 mm.
Actuator for microliter-precision drug pump
For an advanced technology medical device company, we created
a higher-force version of M3-L Smart Linear Actuator using a custom SQUIGGLE motor. The starting point was
previously published work.
The crucial challenges included:
- Increasing force with bi-directional output.
- Integration with an optical encoder and the pump mechanism.
- Meeting the operating power constraints.
