MAGNETECMAGNET-TECHNOLOGIE
1 What are Cool Blueinductive Absorbers
Nanocrystalline Ringcores made out of a ~ 20µm thickamorphous strip changed to nanocrystalline Structure by an annealing Process to a grain size of about 20 Nanometers.This gives about 1000 insulated areas only in the heightdirection of the tape.
The Power losses of Nanoperm is about 1000 times lowerthan from typical Silicon Iron.
The frequency range is fromsome Herz up to the 100 Mega Herz area.

Why Mhz and not kHz ?
Because of the impedance of the Motor, especially the bearings:

Cool Blue Cores are increasing the reliabilityof Motors and complete Machines in the case of maintenance and avalability.
With the new Cool Blue Plus(+) the performance is over 20 % higher
Thank your for your attandance
Cool Blue Cores are absorbing the dangerous electrical noise andchange it to safe thermical energy
Cheap Steel Bearing; No expensive insulated (Hybrid) Motorbearings are needed in many cases
