Magnetic Winding

Exxelia offers industrialization support and technology expertise in the development of stators for use up to 220°C, crucial in various aerospace applications such as actuators and ventilation systems, including cabin, galley cooling, and heating systems. Our expertise extends to advanced technologies like RAM air turbines, which require precise engineering and reliability.


With a robust engineering background in winding, molding, and manufacturing competencies, Exxelia provides optimized solutions for the ramp-up and mass production of stators. Our capabilities include innovative processes such as overmolding and impregnation, whether wet or vacuum, ensuring the durability and performance of critical components like engine and braking cooling systems and alternators.


Exxelia has developed significant expertise in controlling Partial Discharge, a key factor in ensuring low aging and extended Mean Time Between Failures (MTBF) of our products, even in high voltage systems. This ensures our components maintain their reliability and performance over extended periods, supporting the rigorous demands of the aerospace industry.

What quality certifications does Exxelia hold?

Exxelia is certified EN 9100, a quality standard specific to the aerospace, space, and defense sectors. Our facilities are also ISO 9001 certified (quality management), and some are certified ISO 13485 for medical devices. Other industry-specific standards, such as NADCAP or AQAP, may also apply depending on the products and markets.

Why is EN 9100 certification important for the aerospace and space sectors?

The EN 9100 standard ensures a rigorous quality management system tailored to the critical requirements of the aerospace, space, and defense industries. It is required by major OEMs such as Airbus, Safran, Thales, or CNES. This certification guarantees product traceability, risk management, and compliance with international standards.

Are your components certified for use in medical devices?

Yes, some of our facilities are ISO 13485 certified, the quality standard for medical devices. This certification enables Exxelia to design and manufacture components (such as coils, sensors, or capacitors) used in high-reliability medical equipment, including MRI scanners, ventilators, and imaging systems.

What benefits do your certifications bring to the railway sector?

The railway industry demands durability, reliability, and long service life. While a dedicated certification like EN 9100 is not required, Exxelia applies IRIS standards and complies with IEC/EN regulations specific to railway applications. Our quality processes ensure component compliance for trains, metros, and tramways, including fire safety and electromagnetic compatibility.

Are your products compliant with defense standards?

Yes. Exxelia meets defense industry requirements through its EN 9100 certification and compliance with military standards (MIL-STD, STANAG). Our components are qualified for critical applications such as RF systems, embedded electronics, guided munitions, or radar systems. Some products are also subject to customer-specific qualification procedures.

What is Exxelia's "Thermal Optimization" initiative and what are its benefits for magnetic components?

The "Thermal Optimization" initiative aims to design the smallest possible high-reliability components for a specified power rating by incorporating the correct design margin. The main benefits include a better understanding and control of the operating temperature of our magnetic components, leading to size and weight reductions of up to 30%, and optimized thermal dissipation.

How does the "RELIABILITY OF HIGH VOLTAGE COMPONENTS" initiative improve long-term reliability for high-voltage components?

This initiative focuses on designing a control system that mitigates partial discharge inception. The goal is to create the smallest, highly reliable component for specified high operating voltages. The key benefit is achieving long-term reliability at high voltage with no partial discharge.

Can Exxelia SVM’s magnetics solutions address defence or harsh-environment requirements?

Yes. Exxelia SVM serves high-reliability markets such as defence, medical, EV, and communications, ensuring compliance with strict safety and regulatory standards.

What customization options does Exxelia SVM provide?

Exxelia SVM develops fully custom magnetics, offering in-house tooling, MATLAB/FEMM modelling, special core designs, Litz wire constructions up to 350 A, and complete solutions from prototype to packaging.
