Analysis of broken rotor bars in large induction motors Projeto acadêmico sem fins lucrativos desenvolvido no âmbito da iniciativa Acesso Aberto Artigos 407 A new technique to detect broken rotor bars, in large squirrel-cage induction motors is presented. In order to avoid problems in industrial applications, the electromagnetic behavior of induction machines with rotor faults was examined, by ...
This paper presents a method based on neural networks to detect broken rotor bars and end rings in squirrel cage induction motors. In the first part, detection methods are reviewed and traditional methods of fault detection as well as dynamic model of induction motors are introduced using the winding function method. In this method, all stator and rotor bars are considered independently in ord...
There are many methods in literature for canalizing of circulating useful flux from stator core to rotor core without radial movements in induction machines. It is obvious to healing of useful flux with decreasing radial moved zig-zag flux and it increases the motor performance. Magnetic barrier, cutout and using of slits are the most used methods for improve the circulating useful flux in the ...
