Abstract: During field weakening operation time (FWOT), the total iron loss rises and affects the 11 accuracy of loss prediction and efficiency especially if a large range of FWOT exists due to a large 12 voltage drop which rooted from the resistance of the used material. Iron loss prediction is widely 13 employed in investigations for a fast electrical machine analysis using 2-D FEA. This paper proposes 14 harmonic loss analytically by a steady-state equivalent circuit with a novel procedure. 15 Consideration of skin e… Show more

“…Moreover, the voltage drops R s I d and R s I q of the stator winding resistance are taken into account for the iron loss model based on the equivalent circuit, in which Ref. [23] assumed the winding resistance negligible. However, its ohmic value can be large, especially under the field weakening condition.…”

“…Despite this, these voltage drops are ignored by the work done in Ref. [23], which causes a considerable error. The modified IEM-Formula, which can be rewritten based on the steady-state equivalent circuit and Equations (4) and (8), is given as:…”
