Abstract The Fourier series decomposition is applied to compute the electromagnetic performance of surface dual three-phase permanent magnet brushless AC machines. The analytical model is set up in 2D polar coordinates, and the solution regions are divided into slot-opening, slot, air-gap and permanent magnet subdomains. Taking the vector magnetic potential as variable, the Laplace equation in slot-opening and air-gap subdomains, poisson equations in slot and permanent magnet subdomains are solved by the variable separation method. The Fourier coefficients are obtained by the boundary conditions between two adjacent subdomains. The analytical model accounts for the influence of radial/ parallel/Halbach magnetization, internal/external rotor topologies. This model is applicable to fractional-slot concentrated-windings configurations having either all or alternate teeth wound, which can be used to predict the open-circuit, armature reaction and on-load magnetic field distribution. Based on this analytical model, the cogging torque, back-EMF and electromagnetic torque of two winding connections for fractional-slot concentrated-windings are calculated. FE results confirm the validity of the analytical prediction.
