Grain-Oriented Electrical Steel - GOES

ATI Allegheny Ludlum Grain-Oriented Electrical Steel (GOES) is processed under carefully controlled conditions to develop optimum magnetic characteristics in the rolling direction. GOES develops low core losses at high inductions when used as core material in designs with the flux path parallel to the rolling direction. These low losses at high inductions are attained with low exciting currents because of the excellent high induction permeability of GOES. In addition, the normal operating inductions for GOES are sufficiently below the magnetic saturation of the material to allow a comfortable margin of safety in most designs. Processing of GOES is carefully controlled in order to achieve a very high stacking factor for the core material. This stacking factor often exceeds 95% of the theoretical maximum. The high usable magnetic induction of GOES, along with the high stacking factor, allow compact core designs requiring the minimum amount of material to be used in the windings surrounding the core. This contributes to low losses, not only in the core (no load losses), but also allows for the minimum load losses or winding losses in the transformer.
