Abstract

In this paper, two flux-switching (FS) permanentmagnet (PM) (FSPM) wind power generators with 9- and 12-phase windings are designed and comparatively analyzed. Both two generators are designed under the rated specifications of 10 kW output power and 220 V phase voltage at 500 rpm. The static characteristics and power generating performances including output voltage, power and efficiency at rated and variable load/speed conditions are predicted by finite-element (FE) analysis and co-simulation method. FE results show that the 12-phase 24-stator-slot/22-rotor-pole FSPM generator exhibits higher air-gap flux density, higher torque/power density and lower voltage regulation factor. Besides, it has better overload capability than its 9-phase 36-stator-slot/34-rotor-pole counterpart when the load and wind speed exceed the rated level. The comparative study reveals the benefits of lower leakage flux and permeance from larger stator-slot opening and longer magnetic circuit.
