In this paper the iron losses in induction motors are estimated and analysed using time-stepping Finite Element Method (FEM) both with sinusoidal and PWM supply. The iron losses calculation has been carried out by add up the iron losses produced by orthogonal components of the flux density, as if the iron losses produced by these components were independent phenomena. The rotational hysteresis loss...
In this paper, two different methods for iron loss prediction are analyzed. The first method is based on the classical separation of loss contributions (hysteresis, eddy-current, and excess losses). The model requires loss contribution separation using iron loss measurements with sinusoidal supply. In this paper, this method will be called the ldquolow-frequency method.rdquo The second method, named...
The present work compares three different methodologies reported in the literature for the iron loss prediction in magnetic lamination supplied with PWM waveform. The target is the comparison of these methods from an engineering point of view. In particular, the authors analyze the practical use of the methods, such as the measurement and/or calculation procedure difficulties inherent each methods...
