Abstract
The paper is concerned with the development of a core loss model for a variable flux machine using AlNiCo permanent magnets. A relationship between different magnetization levels and the machine core losses is derived experimentally. An analytical core loss model for non sinusoidal flux waveforms in the PM machine is presented. This model is based on an equivalent sinusoidal waveform. In this model, eddy current loss and hysteresis loss have been estimated based on Maxwell's equation. The analytical results from the proposed model are compared with finite element model (FEM) and experimental results.
