Measurement of Iron Loss Using Rotational Magnetic Loss Measurement Apparatus
IEEE Translation Journal on Magnetics in Japan, 1990 Several methods have been proposed for the measurement of the magnetic losses in electrical steel sheet under the condition of rotating flux. The method considered here is based on a determination of the fied quantities and makes use of square-shaped samples and an air gap between the pole faces and the sample.

Maximum Efficiency per Torque Control of Permanent-Magnet Synchronous Machines
Applied Sciences, 2016 High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization.

The Estimation Method Comparison of Iron Loss Coefficients through the Iron Loss Calculation
Journal of Electrical Engineering and Technology, 2013 A new calculation method for iron loss coefficients is proposed by using the Steinmetz equation from Epstein data. The hysteresis loss must have linear characteristic according to the frequency. However, the existing iron loss coefficients are defined by formula of frequency. In this case, the hysteresis loss has non-linear characteristics by frequency.

Energy loss spectra of iron [PDF]
Surface and Interface Analysis, 2008 Abstract We present experimental and theoretical studies of the spectra of electrons backscattered from iron. The single surface and bulk excitation ratio in the energy range between 500 and 4000 eV are calculated. The contribution of single inelastically scattered electrons is derived from a dielectric response theory and from the ...
