| 中文摘要: |
| 针对电动汽车轮毂电机负载下的铁芯损耗问题，提出基于JMAG的电磁分析方案。采用控制变量的方法，通过JMAG-Express参数化模块，组建参数化电机模型，在轮毂电机负载状况下，通过JMAG-Designer和JMAG-RT软件联合仿真，对轮毂电机的铁损进行定量分析，并得出电机铁损对电机效率的仿真数据。结果表明:电机铁芯的材料及其厚度影响着电机的铁损，从而影响电机的效率，即硅钢片材料厚度越小，牌号越低，铁损值越小，在电机的高效区(≥80%)范围内对电机效率的影响越大。由此，可为电动汽车轮毂电机的优化设计和正确选型提供理论依据和实践指导。 |

| Aiming at the problem of iron core loss under the in-wheel motor load, an electromagnetic analysis scheme based on JMAG is proposed. By adopting the method of controlling variables, the parameterized motor model is established by means of JMAG-Express parametric module. In the case of in-wheel motor load, the iron loss of the in-wheel motor is quantitatively analyzed by the joint simulation of JMAG-Designer and JMAG-RT software. And the simulation data of the motor iron loss on the motor efficiency are obtained. The results show that the material and thickness of the motor core affect the iron loss of the motor, thus affecting the efficiency of the motor. The smaller the thickness of the silicon steel sheet material, the lower the grade, the smaller the iron loss value, the greater the effect on motor efficiency within the range of high efficiency area(≥80%)of the motor. Therefore, it can provide the theoretical basis and practical guidance for the optimal design and correct selection of in-wheel motor for electric vehicles. |
