“…The presented methodology of iron loss computation has its roots in the loss separation theory by Bertotti [15] and the Steinmetz theory generalized by Fiorillo [16]. Our proposed model brinks a new component in these theories, namely the segregation of hysteresis loss into rotational and alternating ones, which behave in very different ways.…”

“…The most extended way to define the iron losses is by the widely known loss separation method in which they are divided in three main components: hysteresis losses, classical Eddy losses and excess losses [6,7]. In case of non sinusoidal voltages, the high order harmonics of currents can accentuate the presence of some phenomena such as the skin effect or the minor loops which are not directly taken into account by theses classical methods.…”

“…The prediction iron losses of the existing model keep constant while the actual iron losses vary significantly when temperature changes. On the other hand, the improved model (6) can predict the iron losses with low and stable relative prediction errors even when the temperature changes significantly. This is due to the fact that the improved model (6) can track the iron loss variation with temperature.…”

Abstract-In this paper, the different temperature dependencies of hysteresis and eddy current losses of non-oriented Si-steel laminations are investigated. The measured iron loss results show that both the hysteresis and eddy current losses vary linearly with temperature between 40°C to 100°C, a typical temperature range of electrical machines. Varying rates of hysteresis and eddy current losses with the temperature are different and fluctuate with flux density and frequency. Based on this, an improved iron loss model which can consider temperature dependencies of hysteresis and eddy current losses separately is developed. Based on the improved iron loss model, the temperature influence on the iron loss can be fully considered by measuring iron losses at only two different temperatures. The investigation is experimentally validated by both the tests based on a ring specimen and an electrical machine.Index Terms-iron loss, eddy current loss, hysteresis loss, temperature dependency, electrical machines . In [29], only the temperature dependency of the eddy current loss is considered while the hysteresis loss is assumed to be not influenced by the temperature. In [30], the temperature influence on the total iron loss is simply modeled by introducing an equivalent temperature dependent coefficient which is a mix of temperature influences on both the hysteresis and eddy current losses. However in [27] and [28], it has shown experimentally that the hysteresis and eddy current losses have different temperature dependencies.The aim of this paper is to develop an iron loss model which can consider the temperature dependencies of the hysteresis and the eddy current losses separately. The iron losses at different flux density, frequency and temperature in non-oriented Si-steel laminations are measured firstly by the ring specimen test as will be described in Section II. In Section III, the accuracy of existing iron loss model having variable
