Abstract: This paper presents a comprehensive survey of fault diagnosis and fault tolerant approaches for permanent magnet synchronous machines (PMSM). PMSMs are prominent in the pervading usage of electric motors, for their high efficiency, great robustness, reliability and low torque inertia. In spite of their extensive appliance, they can be quite non-resilient and inadequate in operation when faults appear in motor drive apparatus such as inverters, stator windings, sensors, etc. These may lead to insulation failure, torque fluctuations, overcurrent or even system collapse. On that account, fault diagnosis and fault tolerant methods are equipped to enhance the stability and robustness in PMSMs. Progressive methodologies of PMSM fault diagnosis and tolerance are classified, discussed, reviewed and compared in this paper, beginning with mathematical modeling of PMSM and then scrutinizing various fault conditions in PMSMs. Finally, the scope of research on the topic is highlighted. The contribution of this review is to emphasize optimistic schemes and to assist researchers with the latest trends in this field for future directions. Keywords: Permanent magnet synchronous machine (PMSM), fault diagnosis, fault tolerant control system (FTCS), fault detection, stability.
1 Introduction The consistent increase in greenhouse gas emanations has led to the use of electric motors for numerous purposes since the time they were invented quite a while back[1, 2]. Around then, the safety features of the motors only had simple apparatus, such as fuse elements[3]. With the advancement of human civilization, stability and reliability have become more crucial in motor control systems[4]. However, electric motors often prompt different faults, causing degradation of performance and damage in healthy components. In complex systems, the consequences of faults can be catastrophic. It is extremely important for the systems to be stable and fault resilient, which further may not lead to any enormous situation[5]. Over the previous decades, permanent magnet synchronous motors (PMSMs) have acquired significant ubiquity on account of high efficiency, high power to volume ratio, high torque to current ratio and higher power density[6]. They are utilized in diverse applications in the field of automotive vehicles[7], subway applications[8], aeronautics[9], turbines[10], industry applications[11] and so forth.
