Abstract

Abstract

In an MFCG, the magnetic field generated by the current of stator coils is compressed by the expanding armature. It is important to compute the value of the magnetic field exactly, for it is relevant to the output current of MFCG. Formulas of magnetic field with surface current density and that with point current density are presented. Numerical results prove that the former can describe the magnetic field more accurately than the latter, and the former is more efficient than the latter.
