Low leakage flux, non-oriented electromagnetic steel sheet, and core and
compact transformer using the same
摘要:
This invention relates to a non-oriented electromagnetic steel sheet with low leakage flux for a compact transformer and a method for making the same. After stress relief annealing, the magnetic permeability .mu..sub.C of the sheet in the direction transverse to the sheet rolling direction is.mu..sub.C .gtoreq.about 2.5.times.10.sup.-3 (H/m) and magnetic permeability .mu..sub.D of the sheet in the direction 45.degree. to the sheet rolling direction is .mu..sub.D .gtoreq.about 1.5.times.10.sup.-3 (H/m).
