Whether it is wind power, thermal power generation, or new energy vehicle motor drive work will encounter harmonic current interference, these interferences are mainly in the form of common mode interference, electrical corrosion of the motor bearings, affecting the efficiency and life of the drive system, with nanocrystalline coiled oval common-mode magnetic ring can be an effective solution to the problems encountered in this regard. Nanocrystalline material itself has the advantages of high permeability, high magnetic induction strength, good temperature stability, compared with the traditional ferrite ring, common mode magnetic ring made of nanocrystalline material has the advantages of high inductance, high impedance, easy to produce, easy to install and so on.
