Abstract
The vibration of generators end windings in rotor inter turn short circuit different (RISC) locations is studied in this article. Firstly., the influences of short locations on the air gap magnetic flux density (MFD) are investigated. On this basis., the electromagnetic forces (EF) of end windings are obtained. Then, theoretical analysis model is validated through finite element analysis (FEA) and experiment. It shows that the RISC fault will bring additional (50Hz, 150Hz, 200Hz) harmonics to the EF. In addition, the vibration of the end winding will increase as the short location gets distant from the large tooth.
