Problem
Designers of electric motors, power electronics, and safety-critical systems often face limitations in magnetic component performance, size, and reliability, which can hinder efficiency, power density, and compliance with safety standards.
Solution
VAC (Vacuumschmelze) supplies advanced magnetic alloys, permanent magnets, and inductive components that are engineered to deliver high saturation flux density, low losses, and stable operation across wide temperature ranges. Their nanocrystalline common‑mode chokes provide compact, high‑attenuation filtering for EMI suppression in industrial, automotive, and renewable‑energy applications. Custom fluxgate cores enable precise detection of AC and DC residual currents for safety devices such as RCDs, EV chargers, and solar inverters. By offering a vertically integrated production chain—from raw alloy to finished magnet assemblies and stamped soft‑magnetic parts—VAC ensures optimized form factors, consistent material properties, and rapid delivery to global customers.
Target Audience
Primary customers are OEMs and system integrators in automotive, e‑mobility, renewable energy, industrial automation, and aerospace that require high‑efficiency magnetic components and safety sensors for motors, power converters, and protection devices.
