Professor Sarwate has written a textbook which addresses their problems particularly, yet it should also be very useful to the wider spectrum of students as well. Ironically, in a way, this book may well establish a trend in textbooks in the U.K. because of the wider access to university ...
Figure 5c shows the harmonic spectrum images corresponding to Figure 5b. The fundamental amplitudes were almost the same, while the amplitudes of the harmonics decreased with the airgap length, which agreed well with above analysis. According to Equation (4), the eddy-current loss of the rotor ...
The radial flux densities in the middle of the airgap were plotted in Figure 2f, and the waveforms were highly distorted. Harmonic spectrum images corresponding to the radial flux density were provided in Figure 2g. As can be seen, the amplitude of the working harmonic flux density of case ...
