Analysis of damage to the rotor bars of induction machines

By Roman Henzel

Abstract

This bachelor thesis deals with disorders of induction machines with focus on the failure or damage to the rotor bars or end rings. The work includes a literature research of the low resistance measurement, which can be used to determine the rotor bar resistance of the squirrel cage induction machine. The experimental measurement of the analyzed motor with the following conditions (short-circuit, no-load and load) is also includes. The magnetic model of the machine was described and created in MAXWELL and results were compared with the LabVIEW software (in order to verify the accuracy of the particular simulation). Analysis results evaluation of three phase squirrel cage induction machine with broken rotor bars was done

Topics: equivalent circuit; broken rotor bars; náhradní schéma; rotorová klec.; ANSOFT; Asynchronní stroj; Induction machine; porušené rotorové tyče; rotor cage.
