“…The induction B s is calculated by the r.m.s. value of the inductor line current density, J l , as follows: 5,6) .................. (3) in which, k B represents a reduction factor considering the reaction of the eddy currents induced in the Wood's metal and the nonmagnetic steel vessel, determined for the effective magnetic Reynolds number 6) ... (4) where, Cend denotes the mean value in axial direction of the end effect factor C, computed by the effective radius of the secondary, Reff, in a rotational two-pole magnetic field: 6,7) ........ (5) In Eq. (3), m = 3 is the number of phases, nw the number of series turns per phase of the winding, kw represents the winding factor, I the r.m.s.…”
