Differences between Preisach Model and Experiment for Soft Ferromagnetic Materials, Effect of Instrument Accuracy
Original language description
The practical use of Preisach hysteresis model is based on proper identification of weighting function that characterizes the material. Obtaining of the weighting function needs two partial derivations of two-dimensional flux density function, called Everet surface, measured by specific procedure. Since the derivatives require exact measurements, the possible source of errors are studied. Main method is to compare experimental results and simulation. The comparison showed that the excitation current source accuracy influences the quality of Everet surface. Also the integration drift plays an important role. The random or systematic failure in excitation results in the minor secondary loops on the main hysteresis loop and can be effectively found or eliminated. The simulations showed that the errors in excitation can be reduced by repeated measurements. The used waveform is not the best one, especially the drift can be eliminated, if more harmonic periods are used.
