Abstract :
This paper presents the parameter computation and performance prediction of a permanent magnet (PM) synchronous generator based on numerical magnetic field analyses. The finite element method is employed to accurately determine the magnetic field distribution and key parameters of the machine, such as the winding flux, back electromotive force, winding inductance and core loss. An equivalent electrical circuit is applied to predict the generator performance such as the external characteristic.
