This paper presents a precise analysis of the efficiency characteristic synchronous generator under both normal and SAGE conditions. In this work, various losses are computed by qualitative theoretical model finite element in detail. Further, is proposed according to relationship between output power loss. The presented verified 5-kW non-salient generator. result demonstrates that loss increase...

This paper presents an intelligent fault detection based on adaptive continuous wavelet transform of broken rotor bars for Induction Motor (IM). Broken rotor bars, bearing decay, eccentricity, as motor faults appears as different frequencies in the stator current signals. The stator current and speed signals at deferent operation conditions obtained from the winding function are analysed throug...

The work undertaken in this research focuses on advanced condition monitoring and fault detection methods for wind turbines (WTs). Fourier Transform (FFT) and Short Time Fourier transform (STFT) algorithms are proposed to effectively extract fault signatures in generator current signals (GCS) for WT fault diagnosis. With this aim, a WT model has been implemented in the MATLAB/Simulink environme...

Research on the modeling and fault diagnosis of rotor eccentricities has been conducted during past two decades. A variety diagnostic theories methods have proposed based different mechanisms, there are reviews following either one type electric machines or eccentricity. Nonetheless, research routes common, regardless machine eccentricity types. This article tends to review all possible approac...

In this paper we have classified the nodes of OTIS-cube based on their eccentricities. OTIS (optical transpose interconnection system) is a large scale optoelectronic computer architecture, proposed in [1], that benefit from both optical and electronic technologies. We show that radius and diameter of OTIS-Qn is n + 1 and 2n + 1 respectively. We also show that average eccentricity of OTIS-cube ...

in this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real iranian earthquake records by considering soil-structure interaction. then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of iran, atc-3, new zeland, canada, mexico, austral...
