摘要

设计了一种用于电动汽车(EV)的效率转换径向-轴向混合永磁同步电机(ES-RA-HPMSM),并比较了目前使用单挡或双挡变速器(TR)的电动汽车中使用的传统非效率转换电机(ES-M)的最大行驶距离$(d_{max})$和dmax与电机系统成本的比值$(d_{max}/M_{cost})$。利用MATLAB软件构建电动汽车模型,包括驱动、电机和逆变器、电池组、TR、车轮和底盘模型。在典型的城市、高速公路和城市+高速公路驱动工况下,对具有单档位TR的ES-RA-HPMSM和具有单或双档位TR的非es - m进行了评价。结果表明,ES-RA-HPMSM不仅在城市行驶工况下可将$d_{max}$延长25.4和46.8英里,在高速公路行驶工况下可将$d_{max}$延长30.4和44.9英里,在城市+高速公路行驶工况下可将$d_{max}$延长37.8和19.5英里,而且在城市行驶工况下可将$d_{max}/M_{cost}$分别提高4%和97%,在高速公路行驶工况下可提高21%和86%,在城市+高速公路行驶工况下可提高20%和92%。

Evaluation of Efficiency-Shifting Permanent Magnet Motor in Electric Vehicle
We have designed an efficiency-shifting radial-axial hybrid permanent magnet synchronous machine (ES-RA-HPMSM) for use in an electric vehicle (EV) and compared the maximum driving distance $(d_{max})$ and ratio of the dmaxto the cost of the motor system with transmission $(d_{max}/M_{cost})$ of the conventional non-efficiency-shifting motor (ES-M) used in current EVs with either a single-or two-gear transmission (TR). An EV model, comprising a driver, motor and inverter, battery pack, TR, wheel, and chassis model, was constructed using MATLAB software. The proposed ES-RA-HPMSM with single-gear TR and four non-ES-M with either single-or two-gear TR were evaluated under typical city, highway, and city+highway drive cycles. The results show that the proposed ES-RA-HPMSM not only extends the $d_{max}$ by 25.4 and 46.8 miles in the city, 30.4 and 44.9 miles in the highway, and 37.8 and 19.5 miles in city+highway drive cycles but also exhibits higher $d_{max}/M_{cost}$ by 4 and 97 % in the city, 21 and 86 % in the highway, and 20 and 92 % in the city+highway drive cycles, compared to the conventional motor with single-or two-gear TR, respectively.
