| Summary: | Aiming at the issue of the traditional local optimization method of permanent magnet motor can not achieve multiobjective optimization, an optimization method based on Taguchi method is proposed. By using Taguchi method, air gap length, pole arc coefficient, permanent magnet thickness, stator tooth width and slot width of the fractionalslot concentrated winding permanent magnet synchronous motor are optimized, which makes performances including efficiency, cogging torque, torque produced by unit mass permanent magnet of the motor optimum. The orthogonal matrix is established according to the Taguchi orthogonal experiment. Combining with statistics, the influences of each optimization variable on the optimization objective are analyzed , and the optimal combination of multiple optimization factors are obtained at finally. Twodimensional transient field of the optimized motor is analyzed by using the finite element method, the magnetic field distribution and relevant characteristics of the motor under load conditions are obtained. Experimental data and related analysis show that the Taguchi method is suitable for the optimal design of fractionalslot concentrated winding permanent magnet synchronous motor, and can effectively suppress the cogging torque of the motor. |
