P iron p eddy + p hysteresis
Webbwhere P F e is the power losses in core iron (W); P e d d y is the power eddy currents losses (W); P h is the power hysteresis losses (W). A practical recommendation to reduce eddy currents losses is to build the ferromagnetic cores by coated double-sided areas with a thin layer of insulation, usually oxide insulation. WebbEffective permeability is dependent on the initial permeability of the soft magnetic material and the dimensions of air-gap and circuit. µₑ = µᵢ / {1+ [ (G x µᵢ)/lₑ]} Where; G is the gap …
