An Overview of Reliability of Drive System for Small and Special Electric Machines

The small and special motors have been widely used in a variety of industrial and military applications, where high degree of reliability has been an important requirement for motor drive. Hence, the strategies to improve reliability of motor drive have been an area of great interest for researchers in order to reduce or eliminate the losses of fault. In this paper, the principle of reliability engineering is introduced, and two primary effective ways to improve reliability, namely redundant technique and fault tolerant approach, are applied to motor drive. Moreover, the state of the art in strategies to improve reliability of motor drive in the past thirty years is overviewed, and the merits and drawbacks of the strategies are also analyzed. Finally, the potential techniques to improve reliability of motor drive in the next years are prospected.
