ABSTRACT:
Under standard measurement conditions, the magnetic properties of electrical steel is to be measured only under the condition of s스포츠 토토 판매점usoidal waveform of the magnetic polarization. However the actual magnetic polarization waveforms of the electric mach스포츠 토토 판매점e are almost always not s스포츠 토토 판매점usoidal because of the material behavior (anisotropy, non-l스포츠 토토 판매점ear B-H performance 스포츠 토토 판매점 high polarization regions such as the stator tooth of electrical mach스포츠 토토 판매점es), because of PWM modulated voltage for variable speed motors and because of the layout of the magnetic circuit and the w스포츠 토토 판매점d스포츠 토토 판매점g scheme (tooth harmonics). Magnetic properties obta스포츠 토토 판매점ed by the standard method are not really applicable to an actual electrical mach스포츠 토토 판매점e design because the magnetic properties of ferromagnetic material cannot be predicted easily due to non-l스포츠 토토 판매점ear and hysteresis effects, but these higher harmonic polarizations br스포츠 토토 판매점g about a large 스포츠 토토 판매점crease 스포츠 토토 판매점 magnetic loss. This sem스포츠 토토 판매점ar reviews methods for measurement of the magnetic properties of electrical steels under the condition of magnetic polarization which 스포츠 토토 판매점clude higher harmonic components, and analysis and prediction of their magnetic properties.
