How eddy current losses are minimized
WebAs these currents are not responsible for doing any useful work, and it produces a loss (I 2 R loss) in the magnetic material known as an Eddy Current Loss. The eddy current loss is minimized by making the core with thin laminations. The equation of the eddy current loss is given as: Where, K e – coefficient of eddy current WebWhen magnetic materials are subjected to an alternating flux, two types of losses occur which are: 1. Hysteresis Loss 2. Eddy Current Loss The above losses comprise the …

Web24 nov. 2024 · It is almost impossible to reduce the iron losses completely; however these can be reduced to a certain extent. Here we have made an effort to reduce the eddy current loss by reducing the iron area of core. It has been done by embedding an anti ferromagnetic bar of copper in iron core by keeping total area constant. As we know that …
