Patented Coil-free Actuator Technology

Fluxthor develops a coil-free magnetic actuator that radically improves precision, speed and energy-efficiency.

The patented technology comes forth from scientific research at Delft University of Technology.

Reluctance Actuators

Our technology is based on reluctance actuators. As Fluxthor, we believe that reluctance actuators are the next generation of short-stroke electromagnetic actuators.

Technical Advantages

  • Extreme force density

  • Highly energy efficient

  • Contactless magnetic force

The Working Principle

Reluctance actuators are based on the strong attraction force between magnets/coils and ferromagnetic materials. The electromagnetic force is transmitted directly to the load to be moved without the use of mechanical transmission elements.

Application fields

These actuators are particularly suitable for applications that require high dynamics, high velocities, and energy-efficient actuation. Reluctance actuators inherently have a small displacement range, in the range of a few millimeters.

Revolutionary Coil-Free Actuation Technology

At Fluxthor, we have developed a patented coil-free actuator that revolutionizes precision motion: the Reluctance Tuning Actuator. This innovative design combines hard magnets with reluctance tuning modules to create contactless forces based on the reluctance principle.

Unlike traditional electromagnetic actuators, our coil-free technology eliminates unwanted heat generation, significantly reducing energy consumption and cooling requirements. The reluctance tuning modules dynamically adjust magnetic resistance in a local circuit, creating controlled magnetic flux differences. These flux deltas generate precise, contactless magnetic forces on a ferromagnetic mover, enabling highly efficient and directional motion.

Key Technical Advantages

  • 0% Heat Dissipation During Static Operation

  • 10x More Energy Efficient at High Dynamic Situations

  • Displacement Ranges of Electromagnetic Actuators

  • Minimal Magnetic Field Leakage

However, our technology can also be applied in other actuator configurations or magnetic technologies. Learn more about the possibilities on the our product page.
