Electric motors are widely used in industry and more particularly in transportation systems. They are mostly driven by power electronic drives. Traditionally, power electronic drives and electric motors are considered as two separated entities. A recent trend consists in integrating power electronic drives inside electric motors enclosure. Wide-bandgap (WBG) switches are the key components enabling this trend. This allows reducing significantly losses in the drive. This latter together with optimal design of the motor improves the overall efficiency of the electromechanical conversion system. Indeed, this constant improvement is due to new materials and designs, more performant drives and more effective control hardware and algorithms. However, manufacturing imperfectness as well as degradation and failures due to aging or unexpected operating conditions affect electric motor performances. Electric motors of the future are expected to show more resilient with the best performances possible. In this regard, solutions are emerging in both academia and industry. This research program on Smart Integrated Electric Motor Drives aims to address and reinforce this capability in electric motors of the future by enabling health-monitoring and fault-tolerance in highly integrated motor drives. Though the concept of more resilient electric motor drives can be considered for most of applications, the interest for electrified transportation systems and especially "more electric aircraft" (MEA) and future full electric aircraft is of paramount importance. It is why the target application in this program is air transportation. Indeed, the concept of power-by-wire is developed to improve the performance and reliability of future aircraft. This trend, known as "more electric aircraft" is the major challenge facing the aircraft industry which is undergoing an in-depth revolution where pneumatic and hydraulic subsystems are being replaced by electrical ones. The aim is to enhance reliability and propulsion efficiency and reduce maintenance costs and environmental impact. To get there, the aircraft industry is developing required electronic, electrical, and mechanical components, and looking at new means to protect and monitor them throughout their operating life. The integrated motor drives fit very well with the objective of increasing the efficiency. However, additional functions like health-monitoring and fault-tolerance must be included in the integrated drives to enable their wide use in future aircraft. This is the core of the expected technical outcomes of this program.

电机广泛应用于工业，尤其是交通运输系统。它们主要是由电力电子驱动器驱动的。传统上，电力电子传动和电动马达被视为两个独立的实体。最近的一个趋势是将电力电子驱动器集成到电动马达外壳中。宽带隙(WBG)交换机是推动这一趋势的关键组件。这可以显著减少驱动器中的损失。后者与电机的优化设计一起提高了机电转换系统的整体效率。事实上，这种持续的改进归功于新的材料和设计、更高性能的驱动器以及更有效的控制硬件和算法。然而，由于老化或意外的运行条件导致的制造缺陷以及退化和故障会影响电机的性能。预计未来的电动马达将表现出更强的弹性和最好的性能。在这方面，学术界和工业界都在涌现解决方案。这项关于智能集成电机驱动器的研究计划旨在通过在高度集成的电机驱动器中实现健康监控和容错，来解决和加强未来电机的这一能力。虽然更具弹性的电动马达驱动的概念可以考虑用于大多数应用，但对电气化运输系统，特别是“更电动飞机”(MEA)和未来的全电动飞机的兴趣是至关重要的。这就是为什么这个项目的目标应用是航空运输。事实上，有线供电的概念是为了提高未来飞机的性能和可靠性而开发的。这种被称为“更多电动飞机”的趋势是航空业面临的主要挑战。航空业正在经历一场深刻的革命，气动和液压子系统正在被电动子系统取代。其目的是提高可靠性和推进效率，降低维护成本和对环境的影响。为了实现这一目标，航空业正在开发所需的电子、电气和机械部件，并寻找新的方法，在它们的整个使用寿命内对它们进行保护和监控。集成的电机驱动非常符合提高效率的目标。然而，集成驱动器必须包括健康监测和容错等额外功能，才能在未来的飞机上广泛使用。这是这一计划预期技术成果的核心。
