Next-generation of high-power magnetic components
Smaller, lighter and more cost-efficient
InnoMag develops high-power magnetic components for wind energy, EV charging, Power-to-X and industrial power electronics – helping our customers build more compact, sustainable and efficient systems at a reduced total cost.
The hidden bottleneck in electrification
High-power magnetic components are essential in wind energy, EV charging, Power-to-X and industrial power electronics.
But traditional designs are often large, heavy and material-intensive – making systems harder to scale, more expensive to produce and more dependent on complex supply chains.
To scale electrification, the components behind it need to change.
The world’s first high-power magnetic component using planar technology
A new way to build high-power magnetics
For decades, planar technology has been considered too difficult to apply in high-power magnetic components.
InnoMag has developed a patented planar design for high-power magnetic components – enabling smaller, lighter and more cost-efficient magnetic components that are easier to scale.
With lower material consumption, improved efficiency and better recyclability, sustainability becomes a built-in advantage.
