How eddy current losses are minimized
WebEddy currents are setup in any metallic block which is in the vicinity of changing magnetic fluxes. These primarily cause heat losses, and in certain cases causes damping of the relative motion between the metallic block (where the currents are induced) and the magnet producing the field.To reduce these effects, we use two strategies:- Web24 feb. 2012 · Iron or core losses are further divided into hysteresis and eddy current losses.Eddy current losses are minimized by using lamination on core. Since by laminating the core, area decreases and hence resistance increases, which results in decrease in eddy currents.Hysteresis losses are minimized by using high grade silicon …
