The modulation method in inverter-fed ac-drive applications has a great influence in the performance of the entire system as it generates losses in the converter and the machine, degrades the signal waveform quality and causes additional noise and vibrations. By carefully selecting the modulation method, some of these unwanted effects can be improved. This paper explores the influence of some of the...
Eddy current losses generated in the rotor of the permanent magnet machines may lead to an excessive magnet heating. This can cause full demagnetization of the magnets so it is very important to analyze the losses on them to adopt solutions to reduce eddy current losses. The most common technique is the magnet circumferential segmentation. The segmentation of the magnetic poles usually is the same...
Eddy current losses generated in the rotor of permanent magnet machines may lead to an excessive magnet heating. This can cause the magnets to get fully demagnetized so it is very important to analyze the losses on them. In high power application usually it is necessary to design solutions to reduce eddy current losses. The most common technique is the magnet segmentation. Analytical calculation of...
