High-Precision Vibration Isolation and Positioning Solutions
Custom-Made, based on Reluctance Actuation
Active Vibration Isolation
By using reluctance actuators in active vibration isolation systems (AVIs), we introduce negative stiffness through magnetic attraction. By creating a combination of positive stiffness of leaf flexures and negative stiffness of the actuator, the resultant will be a quasi-zero stiffness vibration isolation system. By tuning the actuator’s negative stiffness, we can actively control and calibrate the system dynamics according to the specific operating conditions.
The resultant stiffness of the system is the crucial variable on the natural frequency of the system, resulting in the first resonance frequency. By setting this value extremely low, we can suppress vibrations at lower frequencies than any commercially available AVI.

Products in Development
Reluctance Actuator
A power full reluctance actuator that can create a highly dynamic motion, dissipating 10x less heat compared to coil based reluctance actuators.
Contactless Magnetic Force Actuation
Coil-free, minimal flux leakage
Vacuum-compatible
Near-zero stiffness achievable
Compact design
Linear Motor
As Reluctance actuators can only move a few millimeters, we are developing a new type of actuator configuration that can use reluctance tuning to displace over a potential infinite displacement range
Motion Controller
Reluctance actuators are hard to control due to their non-linear dynamics. This called us to start developing a in-house controller that can specifically control reluctance actuators in an open-loop
Control & Simulation Software
Understanding and easy of use are critical, we make it easy for all of our customer to configure multi-axis systems and change the control behaviour to match their needs.
