Modeling and Analysis of Induction Machines under Broken Rotor-bar Failures

This paper discusses a novel method for motor fault detection under varying load conditions. Winding Function Approach (WFA) is used to develop a mathematical model to provide indication references for parameters under different load levels and different fault situations. Broken bar defects reference indexes are developed to assess rotor fault severity based on stator current and rotor speed. S...

simultaneous estimation of speed and rotor and stator resistance in induction machines at motoring and generating conditions

most of the methods that have been proposed for speed estimation of induction machines require the rotor and the stator resistance to change in the normal operating range. on the other hand, estimation of the rotor resistance requires rotor speed. in this paper, after studying conditions for simultaneous estimation of rotor speed and rotor resistance, a method for simultaneous estimation of rot...

Separation of saliency information for speed sensorless detection of induction machines flux and rotor position

Purpose – The purpose of this paper is to describe an effective method to eliminate or substantially reduce the modulation harmonics due to saturation and inter-modulation for sensorless speed control induction motor drives at low and zero speed with high loads using artificial neural networks (ANN). Design/methodology/approach – In this paper, the separation of the saturation signal, the slott...

Detection of Broken Rotor Bar Fault in Induction Motor Using Paramter Estimation Approach

The detection of faults in a dynamic system can help to avoid severe damage where system reliability and safety are essential. An induction motor can fail either due to internal faults such as short circuit of motor leads; broken rotor bar and cracked rotor end rings or by external faults such as phase failure, asymmetry of main supply and mechanical overload (Karami et al 2010). Detection and ...

Effect of Harmonics on a Solid-rotor Induction Motor

The paper records a study of an investigating the performance of a solid-rotor induction motor with a rectilinear inverter excitation to identify the effects of the associated time harmonics. The performance is determined experimentally by using a stator of a three-phase laboratory induction motor that is fitted with a solid-steel rotor and compared with the theoretical model developed which us...
