Abstract:
This paper presents the accurate determination of
key parameters and performance analysis of a permanent
magnet synchronous generator (PMSG) by finite element
magnetic field analysis, providing a sound basis for the machine
design and optimization. Parameters such as the winding flux,
back electromotive force, and inductances are accurately
calculated based on a series of numerical field solutions and
improved formulations. An equivalent electrical circuit is
employed to derive the equation of the external characteristic,
the most important performance of the synchronous generator.
The theoretical calculations and analyses have been validated by
the experimental results on the PMSG prototype.
