Reducing Interference and Eliminating Bearing Damage

Danfoss Drives Team 2015/05/12 2021/01/08

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).

Practical Aspects Of AC Mains Systems

Gregers Geilager 2014/08/18 2021/01/08

Various types of AC mains systems are used to supply power to electrical drives. They all affect the EMC characteristics of the system to various degrees. The five-wire TN-S system is the best in this regard, while the isolated IT system is the…
