摘要

在目前的情况下，许多行业面临的关键挑战是开发高功率密度的电机。材料技术的进步有助于工业在更大程度上提高功率密度以及电机的效率。导体在提高机器性能方面起着重要作用。本文讨论了导电材料在高功率密度电机中的作用。石墨烯是一种先进的纳米材料，具有优良的导电性和低质量密度。使用石墨烯涂层绕组，可以显著减少机器的重量和体积。为了了解纳米材料基导体的突出特点，在不同的电动汽车上进行了案例研究，如丰田普锐斯(2017)、日产LEAF和宝马i3。此外，高功率密度电机的主要制约因素是温升，并在最后进行了讨论。

Graphene: future of high power density electrical machines for electric vehicle applications

The key challenges faced by many of the industries in the present scenario is to develop a high power density electrical machine. The advancements in material technology help the industries to enhance the power density as well as the efficiency of an electrical machine to a greater extent. Conductors play a major role in improving the machine's performance. In this paper, the role of conducting materials in high power density electrical machines are discussed. Graphene is an advanced nanomaterial that exhibits excellent conductivities with low mass density. Using graphene coated windings, the weight and volume of the machine can be reduced significantly. In order to understand the prominent features of the nanomaterial based conductors, a case study has been carried out in different electric vehicles such as Toyota Prius (2017), Nissan LEAF and BMW i3. Moreover, a major constraint in high power density machine is the temperature rise, which is discussed at the end.
