This paper proposes the application of analytical scaling laws on existing saturated flux-linkage and loss models for synchronous permanent magnet and reluctance machines. This scalable model is used for fast and accurate calculation of efficiency/loss maps and can also be used for drive cycle analysis including energy consumption. The scalable model is verified by comparison with existing state-of-the-art...
Rotor losses of axial flux permanent magnet (PM) synchronous machines with fractional windings depend on stator magneto-motive force (MMF) harmonics. To reduce rotor losses, a soft magnetic composite rotor can be used. This paper focuses on the comparison between two machines with the same soft magnetic composite stator and different rotor cores: one of solid steel and another of soft magnetic composite...
