Abstract: In recent years, the field-metric method for measuring
the joule losses set up in an electrical steel laminate when subjected to a
rotating field has gained popularity. The ideal geometry of the magnetiser
required to set up such a field is still however the subject of much debate.
The work presented in this paper aims at providing some useful guidelines
which might be considered when undertaking the construction of the simplest
of such magnetizing setups having four salient poles excited by a two phase
system and using a square sample. A 3D model for this rotational power loss
tester was simulated for different pole geometries with the induction
uniformity being assessed for every alteration.
Keywords: Two-dimensional magnetisers, iron losses
