In this paper, more than ten different iron loss models are experimentally evaluated, which cover alternating and rotating fields, influence of temperature, DC bias flux density and distorted flux density due to PWM inverter. Iron loss models considering alternating fields are evaluated by the measured results of a lamination ring specimen. The iron loss model considering rotating field and non-sinusoidal field are evaluated by the measured results of an electrical machine under different conditions. The iron loss models considering temperature influence are also evaluated by thermal analyses and experimental tests. Based on these comprehensive investigations, the iron loss models having the best prediction accuracy for each case are identified.Index terms --Electrical machine, Iron loss, Thermal analysis.Z.Q.

“…6). Here the axis ratio [5], α ratio = B short /B long , was introduced to separate the alternating and rotating magnetic field regions in the stator core. This ratio (confined between 0 and 1) defines the aspect ratio of a particular B-locus, with zero corresponding to a pure alternating field and 1 corresponding to a pure rotating field, where the B-locus resembles a circle.…”

“…Step 3 -the rotating and alternating magnetic fields in the stator core were separated by analyzing the magnetic field behavior using non-linear FE calculations [4,5]. The numbers of nodes where flux densities were calculated, in the teeth's tops, centers and bottoms and the stator yoke were 6, 3, 6 and 20, respectively (Fig.…”

Surface-mounted permanent magnet (PM) machines were examined experimentally and theoretically, through power loss measurements and calculations. Windage, friction and copper losses were calculated using simple analytical equations and finite element (FE) analyses. Stator core losses were calculated by determining core loss coefficients through curve-fitting and magnetic behavior analysis through non-linear FE calculations. Rotor eddy current losses were calculated using FE analyses that considered the time harmonics of phase current according to load. Core, windage and friction open-circuit losses and copper loss were determined experimentally to test the validity of the analyses.
