Atlas - Reluctance Actuator
The Atlas, a pure reluctance actuator consisting solely of ferromagnetic material, coils, and a compliant mechanism, requiring no rare-earth magnets. Reluctance actuators deliver the highest force-density of all electromagnetic actuators, with or without permanent magnets.
The Atlas is the ideal choice when you need maximum force in a compact, cost-effective package without rare-earth material dependency. Connect it to your controller and driver, and leverage our current-control models for immediate operation.
Key Advantages
Supply Chain Independence
By only using ferromagnetic materials and no rare-earth magnets. Mitigates exposure to rare-earth price volatility or geopolitical supply risks
Highest Force Density
Reluctance force scales with current², compared to Lorentz actuators. enabling superior force-to-volume ratios
Thermal Robustness
No demagnetization risk of permanent magnets. Ensuring consistent performance across extreme temperature ranges
