Induction Motor especially the squirrel cage type of this motor plays important role in industry. According to the application type, this motor place against various stresses that are caused failure in the motor. The most common failure is related to the Stator winding. Among these failures are turn-to-turn, coil-to-coil and phase to phase faults. Flow the high current do to the induction resul...

: استفاده از نیروی الکترومغناطیسی جهت پرتاب اجسام در سالهای اخیر بسیار مورد توجه محققان و مراکز تحقیقاتی قرار گرفته است. پرتاب کننده های الکترومغناطیسی قادرند پرتابه را با سرعت چندین هزار متر بر ثانیه پرتاب کنند. حل مسائل پرتاب کننده الکترومغناطیسی از نظر محاسبات جزو پیچیده ترین مسایل می باشد که البته روش اجزای محدود برای حل این گونه مسائل بسیار مفید است. بیشتر محققین در پژوهش های انجام شده در ...

In this paper, a novel method is presented for detection and classification of the faultyphase/region in the stator winding of synchronous generators on the basis of the resulting harmoniccomponents that appear in the terminal voltage waveforms. Analytical results obtained through DecisionTree (DT) show that the internal faults are not only detectable but also they can be classified andthe rela...

rotating machines in particular induction electrical machines are important industry instruments. in manufacturing, electrical motors are exposed to many damages, and this causes stators and rotors not to work correctly. in this paper we addressed modal analysis and an intelligent method to detect motor load condition and also the stator faults such as turn-to-turn and coil-to-coil faults using...

strength and duration, that have, so far, characterized economic activity. January 31, 2001: Preliminary real GDP growth for the fourth quarter is barely above 1 percent, more than 4 percentage points below what is was only two quarters before and about 7 percentage points below its level in the third quarter of 1999. Much of the press, and some forecasters, predict that the first quarter of 20...
