Correlation of Titanium Content and Core Loss in Non-oriented Electrical Steel Sheets
The core loss of electrical steel is defined as the dissipation of electrical energy in the form of heat during magnetization by an alternating current. Many efforts have been made to reduce the core loss. Numerous parameters, including the chemical composition and the metallurgical technology, influence the properties of the steel. Electrical steel sheets are mainly produced from Fe-Si-C alloy...
متن کاملCore loss models in electrical steel sheets with different orientation
Classical core loss models such as two components model or modified Steinmetz model are still popular and used by engineers to loss prediction in electrical machines. They may carry to increase discrepancy between calculated and measured values. This discrepancy increases with grain-orientation and with increasing discrepancy from sinusoidal magnetisation conditions. Statistical loss model show...
متن کاملComparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester
Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

متن کاملAnalytical Model for magnetic Anisotropy Dedicated to Non-Oriented Steel Sheets
Recent investigations on magnetic properties of Non-Oriented steel sheets enhance the comprehension of the magnetic anisotropy behaviour of widely employed electrical sheets. Our investigation consists of developing an analytical model to consider these magnetic properties while modelling electromagnetic systems. From rotational measurements, the anhysteretic curves are interpolated in order to...
