  • The design of superconducting machines requires a knowledge of the magnetic characteristics of non-oriented soft magnetic materials at low temperatures. Therefore the performance of the electrical steels has to be examined under the given temperature constraints. This report shows that operating the steel at low temperature leads to increased iron core losses and an increased relative permeability. The losses are separated in different loss components and the loss components are quantified.
