Modelling and prediction of iron loss with complex flux waveforms

Charton, J.T., Corda, J., Hughes, A., Stephenson, J.M. and McClelland, M.L. (2005) Modelling and prediction of iron loss with complex flux waveforms. IEE Proceedings - Electric Power Applications, 152 (4). pp. 862-870. ISSN 1359-7043


The paper describes the first phase of a project to improve the prediction and modelling of iron loss for use in the design of switched-reluctance (SR) machines. Earlier models are reviewed and the development of a comprehensive model is described. Its parameters are obtained from commonly available manufacturers’ data and this allows the prediction of not only average loss but also instantaneous power flow for a given flux waveform. Its validation against experimental measurements for sinusoidal and triangular fluxes up to 2 kHz, including superimposed DC bias, is demonstrated. The measurement work using toroidal specimens reveals some unexpected behaviour and a challenge to the measurement technique.
