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).

ATEX and Explosive Atmospheres

Drive systems often operate in potentially explosive atmospheres. One example is the inflow area of a sewage treatment plant. If frequency converters are used for speed control of drives in such areas, the facility must fulfil special conditions. The basis for this is provided…
