Time Stepping Finite Element Analysis of Broken Bars Fault in a Three-phase Squirrel-cage Induction Motor
Broken rotor bars and end-ring are common faults in three-phase squirrel-cage induction motors. These faults reduce the developed toque and increase the speed fluctuations of the motor. Meanwhile, developed unsymmetrical magnetic generates noise and vibration in the motor. Local heat around the broken bars may gradually break the adjacent bars and the motor will be finally out of service. Finit...
متن کاملDetection of broken rotor bars in three-phase squirrel-cage induction motor using fast Fourier transform
Induction motors have become the most used electrical motors in the world. They are rugged, easy to maintain, low in cost and good in performance. Those benefits have made induction motors very popular among users. During their exploitation period induction motors are exposed to various stresses that can become fatal to their performance and bring with them huge economic losses and safety risks...
متن کاملDetection of broken rotor bars in squirrel cage induction motor using filter and wavelet analysis
A new method has been developed for the detection of broken rotor bars fault in squirrel cage induction motor during startup regimes. The incipient detection of fault is made by using DWT analysis of FIR low pass filtered original startup transient current signal. The extracted particular characteristic evolution of the time-varying signal is used as a fault index. The method was tested using h...
متن کاملBroken Rotor Bars Detection in Squirrel-cage Induction Machines by Motor Current Signature Analysis Method
Condition monitoring is an important issue in the maintenance of electrical machines. In the last years several methods for fault diagnosis of the squirrel-cage induction motors were cited in the literature. Among these methods the Motor Current Signature Analysis (MCSA) is considered the most effective non-invasive fault detection method, because it can easily detect all the common electrical ...
متن کاملTransdesign Of A Three Phase Squirrel Cage Induction Motor
Transdesign is the process of converting an idea that has already been used into another one by adding compensation or removing an information in order to modify it to suit a particular purpose. This paper presents the redesign concept as a radical method of revamping a dead electric motor back to usefulness. Data for this paper was got from direct measurement of parameter of a 2.5Hp discarded ...
