This article addresses the benefits of novel dual rotor machine for automobile sector. In case of traditional electric vehicle technology, the vehicle has a single rotor electric machine that can able to perform motoring or regenerative operation and can be possible according to the energy available in the battery. To overcome the above-mentioned problem, novel electric machine design topology with dual operation of motor and generator at same instances of time is proposed with improved electromagnetic, thermal and mechanical transmission losses. The design can be possible by adopting 7.2 kW claw pole alternator and 15 kW brushless permanent magnet synchronous machine as a dual rotor machine considering in-wheel concept. The performance analysis of the machine is done by using finite element analysis technique. The electromagnetic compatibility of machine is performed by three-dimensional transient solver in MagNet software. The electromagnetic analysis of machine is improved by introducing notches in the stator and permanent magnets in the rotor. Based on the electromagnetic results, thermal analysis of machine is calculated by coupling transient analysis using ThermNet software. The simulation results of machine are validated by using electric vehicle Powertrain blocks. The real-time performance of the machine is tested with real-world drive cycle using simulation software. The result substantiates the novelty of this design for improving the driving range of the vehicle for electric vehicle applications.

本文介绍了用于汽车领域的新型双转子电机的优势。在传统的电动车辆技术的情况下,车辆具有单转子电机,该单转子电机能够执行电动或再生操作,并且根据电池中可用的能量是可能的。为了克服上述问题,提出了一种新颖的电机设计拓扑结构,其在相同的时间实例中具有电动机和发电机的双重操作,并改善了电磁,热和机械传输损耗。考虑轮内概念,通过采用7.2 kW爪形极交流发电机和15 kW无刷永磁同步电机作为双转子电机,可以进行设计。机器的性能分析是通过使用有限元分析技术完成的。机器的电磁兼容性由MagNet软件中的三维瞬态求解器执行。通过在定子中引入槽口和在转子中引入永磁体,可以改善机器的电磁分析性能。根据电磁结果,使用ThermNet软件通过耦合瞬态分析来计算机器的热分析。通过使用电动汽车动力总成模块验证了机器的仿真结果。使用仿真软件,通过真实的驾驶循环测试机器的实时性能。结果证实了这种设计的新颖性,以改善电动汽车应用中车辆的行驶里程。通过在定子中引入槽口和在转子中引入永磁体,可以改善机器的电磁分析性能。根据电磁结果,使用ThermNet软件通过耦合瞬态分析来计算机器的热分析。通过使用电动汽车动力总成模块验证了机器的仿真结果。使用仿真软件,通过真实的驾驶循环测试机器的实时性能。结果证实了这种设计的新颖性,以改善电动汽车应用中车辆的行驶里程。通过在定子中引入槽口和在转子中引入永磁体,可以改善机器的电磁分析性能。根据电磁结果,使用ThermNet软件通过耦合瞬态分析来计算机器的热分析。通过使用电动汽车动力总成模块验证了机器的仿真结果。使用仿真软件,通过真实的驾驶循环测试机器的实时性能。结果证实了这种设计的新颖性,以改善电动汽车应用中车辆的行驶里程。通过使用电动汽车动力总成模块验证了机器的仿真结果。使用仿真软件,通过真实的驾驶循环测试机器的实时性能。结果证实了这种设计的新颖性,以改善电动汽车应用中车辆的行驶里程。通过使用电动汽车动力总成模块验证了机器的仿真结果。使用仿真软件,通过真实的驾驶循环测试机器的实时性能。结果证实了这种设计的新颖性,以改善电动汽车应用中车辆的行驶里程。
