Estimation of losses in the stator and rotor of interior permanent magnets synchronous (IPMs) machines using reluctance network Reluctance

An accurate estimation of losses becomes more and more important in the design process of permanent-magnet (PM) synchronous machines (PMSM). This estimation is also a key issue of thermal design. Therefore, the study of losses (in particular non-conventional losses) is of great importance. In this paper, the authors present a calculation of the stator, rotor and PMs losses for different types of fed and working condition (at no-load and at load with supply sinusoidal current). The developed model was validated by using 2-D finite-element method.
