Patented Coilless Actuator Technology

We, as Fluxthor, have developed a coil-free reluctance actuator design. Our patented technology is proven by scientific research from 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

  • Very high force density (motor constant) per volume

  • Very energy efficient

  • Contactless magnetic force

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.

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: No current is needed to maintain force.

  • Exceptional Energy Efficiency at High Speeds: Minimal heat generation compared to electromagnetic actuators.

  • High Control Bandwidth: Free from the physical limitations of coils.

  • Elimination of Coil Flux Leakage: Ensuring optimal magnetic performance.
