Abstract :
Precise permanent magnet generator modeling requires a complex electromagnetic field analysis in order to account for rotor eccentricity and end-zone leakage field. The paper presents a particular technique that enables considering such phenomena through convenient 2-D and 3-D finite element models and incorporate electromotive force distributions including space harmonics in real time control systems. The proposed methodology has been validated by measurements on a permanent magnet wind generator prototype.
