The company
MagniX is redefining the future of aviation with cutting-edge electric propulsion systems. As pioneers of electric flight, they powered the world’s first commercial electric aircraft — the eBeaver — and followed up with the eCaravan, the largest all-electric commercial aircraft to date. Their high-performance electric motors and inverters are pushing the boundaries of sustainable air travel.
The challenges
Transforming traditional aircraft into electric-powered machines isn’t easy — especially under the rigorous demands of the aerospace industry. magniX faced several challenges, including:
- Validating complex controller software under tight timelines.
- Simulating electric propulsion systems (motors and inverters) before hardware was available.
- Replacing traditional gearboxes and heavy turbine engines with compact electric systems.
- Testing systems under strict safety and performance regulations.
To bring their vision of electric flight to life, magniX needed a way to quickly and accurately simulate real-world hardware behavior—without taking to the skies.
The objective was to test the control software designed for the flight in a very short period of time. OPAL-RT systems helped in the rapid modeling and emulation of hardware used for the verification and validation of the software.

The OPAL-RT solution
To speed up R&D and secure safe flight tests, magniX deployed an OP5707 real-time simulator using OPAL-RT’s FPGA-based eHS Power Electronics Toolbox and RT-LAB platform.
Key benefits of their OPAL-RT setup included:
- Real-time emulation of inverter and motor behavior with <400 ns time steps.
- Rapid modeling of R-L load and motor systems for controller validation.
- Integration with physical controller boards via intuitive peripherals and connectors.
- Python-based API for automated testing and reduced human error.
- Scalable HIL testing for magniDrive inverters and magni-Series motors.
The results
- Enabled the first-ever electric flight of a commercial aircraft (eBeaver).
- Validated and integrated magniDrive inverters into the eCaravan, the world’s largest electric commercial plane.
- Reduced controller software bugs early in development.
- Achieved seamless integration thanks to OPAL-RT’s documentation, support, and hardware interfaces.
- Delivered dramatic savings: the eBeaver’s 30-minute flight cost just $8.20 in power vs $135 in jet fuel.
During setup and installation, the OPAL-RT team was very supportive and responsive. The connectors and peripherals provided by OPAL-RT were seamless and easy to integrate with the control module and the measurement units. The documentation, examples and training provided by OPAL-RT helped to set up the system in no time.
