A Survey of Multi-Sensor Systems for Online Fault Detection of Electric Machines

Abstract

A survey of the existing multi-sensor systems for condition monitoring and fault detection of electric motors is presented in this paper. Various types of sensors and their capability of serving as information sources are discussed and compared. This paper then listed a series of different type of multi-sensor systems examples. Different fusion models and their best fitted situation are detailed. At the end of the paper, feasibility of different type of systems is compared. The potentials and shortcoming of multi-sensor systems are also discussed.
