Nanoperm Nanocrystalline Cores

Nanocrystalline cores are indispensable for EMI applications, mainly for common-mode chokes (CMC), for high nominal and unbalanced currents. Magnetec offers a unique combination of Nanoperm cores to reduce motor bearing currents in inverter-motor systems (up to 1200 kW) with long cables.

The CoolBlue line has been specially designed to be used like a CMC (also called inductive absorber) where all phases of the motor cable or bus bars are pulled through the core. NaLA cores reduce high-frequency noise further when added over each single phase. Since usually no winding is applied, installation or retrofit are easy (stack as many cores as necessary for noise reduction) and save maintenance and replacement costs.
