The heart of space craft power systems

At Flux, we understand that magnetics play a critical role in space technology. From propulsion systems to shielding and attitude control, magnetic components are at the heart of modern spacecraft, ensuring their reliability and functionality in the harsh environment of space.

Flux’s mechanical and electrical design teams shape innovation. Our everyday work most often revolves around our cutting-edge electromagnetic components and electrical designs, but behind every successful product lies the expertise of our mechanical design team, which ensures that each component fits seamlessly into existing applications. The collaboration between our Mechanical and Electrical Design Departments is a cornerstone of our innovation, and it's time to share how this synergy drives Flux forward.

The role of magnetics in space

Magnetic technologies are fundamental to various space applications, enabling essential functions such as:

• Power Conditioning Systems: These systems ensure stable and efficient power distribution within spacecraft through components such as PCDU, EPC, DCDC, and POL units.

• Electronic Motor Controls: These are used for precise movement in spacecraft, whether deploying solar panels, adjusting sensors, or operating robotic mechanisms.

• Attitude Control: Electromagnetic torque rods interact with planetary magnetic fields to help maintain and adjust a satellite’s orientation.

• Magnetometers: These instruments measure magnetic fields in space, helping to analyze celestial bodies and ensure mission stability.

• ION Propulsion: An electrical propulsion system (EP) using magnetic fields to accelerate ions, enabling long-duration space missions with minimal fuel requirements.

• Magnetic Shielding: Protecting onboard electronics from electromagnetic interference, ensuring the safe operation of spacecraft systems.

How Flux contributes to space missions

Since 1995, Flux has been a pioneer in developing bespoke magnetic components for space applications. As an ESA Technology Flow Qualified Manufacturer since 2019, Flux is among a select group of companies worldwide capable of delivering components that meet the highest standards of reliability and performance.

With decades of expertise in high-reliability magnetic components, we develop and manufacture inductors, transformers, and other custom magnetics that meet the stringent demands of space applications. Our components are integral to critical spacecraft systems, including power supply units, control electronics, and advanced scientific instruments. 

Operating in space requires components that can withstand extreme temperatures, radiation exposure, and mechanical stress during launch. At Flux, we design and qualify our magnetic components to ensure long-term performance and reliability in these challenging environments.

We take electromagnetic compatibility seriously, ensuring our solutions meet strict requirements to minimize interference between onboard systems. This attention to detail enhances the overall safety and efficiency of space missions.

Pushing the boundaries of space technology

At Flux, we continuously innovate to support the evolving needs of the space industry. Our collaborations with leading aerospace companies and research institutions allow us to refine and enhance our solutions, contributing to the future of space exploration. Explore some of our recent cases with Space Inventor, Micross, and Orbex to learn how Flux operates as a partner in performance 

By combining cutting-edge magnetic technology with our deep engineering expertise, we help spacecraft operate more efficiently, safely, and reliably—paving the way for discoveries beyond Earth’s atmosphere.
