Applications and Specifics

This chapter deals with the diagnosis and prognosis of: AC electrical machines, the storage capacitors, and the inverter. The electrical machines, operating as motors or generators, are the main parts of electrical drive systems. The chapter focuses on two general types of machines, synchronous and asynchronous or induction ones. Discussing faults, their detection, diagnosis, and prognosis, it covers quickly the basics of the operation of these machines types. The chapter also discusses open and short faults, eccentricity, broken magnets and rotor bars. It provides the information on power electronics and systems. The chapter aims to demonstrate the wide breadth of signals and techniques used for the diagnosis on Induction Machine faults.
