Abstract :
This paper presents the experimental determination of iron losses in an outer-rotor permanent magnet synchronous machine (PMSM) by using an inverse thermal model (ITM) in connection with transient thermal measurements. First, the theory and assumptions lying behind the method are presented. Afterwards, 3D finite element method (FEM) based simulations are used to determine the flux density distribution and iron losses in the magnetic steel parts of the investigated machine. Thermal measurements are conducted to determine local iron losses in the stator tooth tips using the ITM. Finally, measurement and FEM simulation results are compared.
