Abstract
Two methods to minimization of the cogging torque in low-speed permanent magnet wind power generator are presented in this paper. The methods are optimizing the magnet pole arc and optimizing slot/pole matching. A simple original model of the cogging torque mechanism and a Fourier analysis are proposed. The methods are applied to design low-speed permanent magnet wind power generator and their performance are calculated by finite element analysis (FEA).
