Abstract - Some of the electric generator stator core faults can be traditionally detected by means of the high induction iron test consisting in inducing a magnetic induction of about 1.0 -1.4 T to …

Research design of the given study includes both analytical calculation of stator core vibration from electromagnetic forces and a case study on site. The report will provide review of the …

In one case with upgrade work on a 50 MVA hydro generator, which included replacement of the stator core, the author has achieved a reduction in core losses from 290 kW down to 160 kW. …

The purpose of the stator core air ducts is to support the stator core iron while increasing the core surface area for cooling the core. The stator core clamping system consists of basically four …

Apr 10, 2009 · Abstract: In the preceding paper hydro generator constructional features and causes of core losses were presented. This second paper will further cover the definition of …

Experience with Hydro Generator Stator Noise due to Air Gap Harmonic Forcing. Thomas J Cunningham, P. E. Fellow Engineer. ElectroMechanical Engineering Associates, Inc. …

This paper examines a hydro generator where a loose rim problem was identified after refurbishment work that included changing the rotor poles, as well as incorporating additional …

Stator core is built from thin laminations to minimize the transformer type electrical losses and of specially rolled silicon steel to minimize hysteresis losses. The inner diameters of laminations …
