Through a complex interplay with Earth’s magnetic field, onboard magnetorquers can automatically register and adjust the satellite’s position, with little-to-no consumption of fuel. Composed of a simple and durable magnet coil, magnetorquers offer a reliable, low-risk solution for attitude control systems.
Magnetorquers also require very little power to operate, even over extended durations. Compared to alternatives, magnet coils have much fewer points of failure. Their simple and reliable design is critical for equipment that must continually endure radiation, vacuum forces, and radical temperature shifts.
Custom Coils is at the forefront of resolving some of the most demanding challenges facing satellite technologies. Drawing on over 45 years working closely with the most successful satellite manufacturers, we’ve honed the possibilities of specially engineered magnetorquers for mission-critical aerospace applications.
Manufacturing Capabilities & Services
From design and prototyping to scalable manufacturing and final assembly, our custom magnetorquers services meet the highest marks of quality. We work closely with each client to fully understand their technical goals and fine tune our process:
Engineering Design Support
Our experienced engineers look closely at each specification and design challenge. Advanced CAD modeling and digital simulations further assist our combined efforts to determine how to balance every possible design element, from weight and size limitations to exact torque specifications and power requirements.
Rapid Prototyping & Testing
We also provide in-house prototyping to quickly bring designs into reality. Custom magnetorquer prototypes undergo thorough design validation and testing procedures, including vacuum/thermal tests and magnetic moment output, to rule out any design errors before authorizing full production runs.
Precision Coil Winding & Assembly
To enhance performance and maintain uniform magnetic fields, Custom Coils applies specialized coil winding and tooling methods. Using only the highest grade magnet wire insulation, we’re capable of meeting the tightest tolerance windows and performance requirements for each individual component (e.g., air-core coils and magnetorquer rods).
Scalable Manufacturing
By continually investing in modern manufacturing technology, our facility supports all production volumes. From small-batch runs for experimental satellites to full-scale production for constellations, Custom Coil applies the aerospace industry’s strictest quality controls. Each production phase is subject to inspection and automated testing to maximize consistency at any scale of production.
Designed for the Rigors of Space
Wielding extensive knowledge of aerospace-grade materials, our design engineers apply advanced material science methods to maximize thermal and radiation management. Doing so has the added benefit of extending magnetorquer service life and meeting other essential factors for harsh space conditions (e.g., minimizing magnetic hysteresis over temperatures and preventing off-gassing in space vacuums).
Industry Knowledge and Quality Assurance
Since 1978, Custom Coils has been at the forefront of advanced magnet coil technology to resolve engineering challenges unique to aerospace environments. To this day, our enduring legacy gives modern satellite manufacturers confidence in our hard-won industry knowledge and technical capabilities.
As the aerospace sector has strict regulations regarding quality and safety, Custom Coils can ensure that all parts manufactured meet ISO, NEMA, and UL standards with 100% traceability.
