Comparative Analysis of Two Permanent Magnet Fractional Slots Synchronous Generators with Different Number of Phases 15 slots /16 magnets three-phase generator to 15 slots/18 magnets five-phase generator : 15 slots /16 magnets three-phase generator to 15 slots/18 magnets five-phase generator

Abstract

this paper presents a comparative FEM analysis of two types of permanent magnet generators with fractional slots. The first one, fractional slot designed, is with three phases, 16 magnets, and 15 slots (3PMSG), and the second one, with the same stator but different winding connection, for five phases, but with a different number of rotor magnets, 18 magnets, and 15 slots (5PMSG).
