Ac 바카라 양방 배팅 properties measurement under 바카라 양방 배팅 induction waveforms …

Under standard measurement conditions, the 바카라 양방 배팅 properties of electrical steel is to be measured only under the condition of sinusoidal waveform of the 바카라 양방 배팅 polarization. However the actual 바카라 양방 배팅 polarization waveforms of the electric machine are almost always not sinusoidal because of the material behavior (anisotropy, non-linear B-H performance in high polarization regions such as the stator tooth of electrical machines), because of PWM modulated voltage for variable speed motors and because of the layout of the 바카라 양방 배팅 circuit and the winding scheme (tooth harmonics). 바카라 양방 배팅 properties obtained by the standard method are not really applicable to an actual electrical machine design because the 바카라 양방 배팅 properties of ferro바카라 양방 배팅 material cannot be predicted easily due to non-linear and hysteresis effects, but these higher harmonic polarizations bring about a large increase in 바카라 양방 배팅 loss. This seminar reviews methods for measurement of the 바카라 양방 배팅 properties of electrical steels under the condition of 바카라 양방 배팅 polarization which include higher harmonic components, and analysis and prediction of their 바카라 양방 배팅 properties.
