Reducing Interference and Eliminating Bearing Damage

High-frequency common-mode core filters reduce electromagnetic interference and eliminate bearing damage by electrical discharge. High-frequency common-mode (HF-CM) cores are special nanocrystalline magnetic cores which have superior filtering performance compared to regular ferrite cores. They act like a common-mode inductor (between phases and ground).
