摘要：

This article proposed a nonlinear analytical model (NAM)-embedded optimal design procedure for permanent-magnet synchronous motors with an external rotor. Combined with the winding inductance calculation, a refined magnetic circuit is proposed for the analytical prediction of the electromagnetic performance. The stator nonlinearity, which is significant in torque prediction, is considered by using the conception of saturation current. Then, ant colony algorithm is employed for the multi-objective optimization for the great potential in global exploring. Finally, optimal design parameters are selected from the Pareto front. The effectiveness of the proposed optimization design method is verified by finite-element analysis (FEA) and experimental results of the manufactured prototype.
