In order to improve the driving capability of the permanent magnet synchronous motor (PMSM), this paper optimizes the stator slot and rotor optimization variables of PMSM with the average torque and torque ripple as the optimization objectives. Firstly, the sensitivity analysis is used to find out the optimization variables which have a greater influence on the optimization objective from the initial selection of optimization variables. Secondly, the Taguchi method and Finite element method (FEM) are used to derive the best combination of optimization variables. Finally, the initial and optimized FEM model is built. The results showed that the average torque of the motor was improved by 27.27% and the torque ripple is reduced by 46.99% after the optimization is done.

In this paper, a new hybrid excitation drive motor (HEDM) was proposed to solve the problem of an uncontrollable magnetic field of a permanent magnet motor. The rotor part of the motor was composed of a combined magnetic pole permanent magnet rotor and a brushless electric claw rotor, in which the combined magnetic pole permanent magnet rotor has a parallel magnetic circuit structure. According to the characteristics of the parallel rotor structure, the equivalent magnetic circuit model was established, and the no-load leakage flux coefficient of the claw pole rotor was calculated. The Taguchi method was used for objective optimization of the permanent magnet rotor structure. The distortion rate of no-load back electromotive force (EMF) was taken as the first optimization goal; the cogging torque and the average torque were taken as the second optimization goal; and the torque fluctuation coefficient was a constraint condition. The optimal parameter matching under the mixed horizontal matrix was obtained. The parameters of the claw pole were optimized by using the method of uniform variables, and the dimension parameters of the motor were obtained. Finite element analysis and prototype tests were carried out for the optimized motor structure. The rationality and feasibility of the new HEDM as a vehicle motor were verified, which provided a possibility for the application of the new energy vehicle drive motor field.

To reduce the manufacturing cost, the cogging torque and the torque ripple of the traditional V-shaped permanent magnet motor (TPMM), an asymmetrical less-rare-earth permanent magnet motor (ALREPMM) is proposed. An equivalent air-gap flux density model is established, the model is employed to calculate the analytical expression of the no-load back-EMF, and the multiple objectives optimisation are carried out for the motor parameters based on the Taguchi algorithm. Electromagnetic performance of the TPMM structure and the ALREPMM structure is compared by finite element method-based simulation. It is shown that the ALREPMM structure can reduce the amount of rareearth materials by 19%, and the cogging torque and the THD values of no-load back-EMF are reduced by 77.3% and 26.8%, respectively. Finally, a prototype is manufactured, thus verifying the rationality of the design of the ALREPMM structure through experiments.
