On the variation with flux and frequency of the core loss coefficients in electrical machines [PDF]
, 2006 A model of core losses, in which the hysteresis coefficients are variable with the frequency and induction (flux density) and the eddy-current and excess loss coefficients are variable only with the induction, is proposed. A procedure for identifying the

Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]
, 2003 A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and
