The magnet core for a trans ductor roller the controller and the use of trans ductor roller regulators and method for producing magnetic cores for trans ductor roller controller

摘要

The invention relates to a transductor regulator with a magnetic core which is made up of a nanocrystalline alloy which is almost free of magnetorestriction. The core has as low cyclic magnetization losses as possible and as rectangular a hysterisis cycle as possible. Said alloy has the composition: FeaCobCucM'dSixByM''z, M' representing an element from the group V, Nb, Ta, Ti, Mo, W, Zr, Hf or a combination of these and M'' representing an element from the group C, P, Ge, As, Sb, In, O, N or a combination of these and the following conditions applying: a + b + c + d + x + y + z = 100 %, with a = 100 % - b -c - d - x - y - z, 0 /= b /= 15, 0,5 /= c /= 2, 0,1 /= d /= 6, 2 /= x /= 20, 2 /= y /= 18, 0 /= z /= 10 and x + y 18. The inventive transductor regulators are particularly advantageously used in motor vehicle voltage supplies, rail power supplies or in aircraft power supplies.
