Determination of the charge angle of the synchronous engine with permanent magnets

Abstract

It was analyzed the dependence of the electromotive voltage and the voltage decline of the synchronous engine on the charge angle and the power factor. It has been proved that the electromotive voltage has a minimal value and corresponds to the optimal dimensions of the permanent magnets for the relation of the  charge angle and the φ angle of the power factor. There were obtained mathematical relations that can be used to determine the synchronous engine parameters with permanent magnets at the project phase.
