Analytical Modeling of a Permanent-Magnet Synchronous Machine in a Flywheel

IEEE Transactions on Magnetics, 2007
We develop an analytical model for a radial-flux external-rotor permanent-magnet synchronous machine (PMSM) without slots in the stator iron and with a shielding cylinder. The machine is part of an energy storage flywheel, to be used as the peak-power unit in a hybrid electric passenger bus.

Vectorial Formalism of Polyphase Synchronous Machine With Permanents Magnets

Aceh International Journal of Science and Technology, 2013
Abstract- This paper presents a mathematical model that transforms the real machine to fictitious machines and our goal is to simulate these and see the behavior of these machines in load. The polyphase machines are developed mainly in the field of variable speed drives of high power because increasing the number of phases on the one hand allows to ...
