Extraction of Frequency Information for the Reliable Screening of Rotor Electrical Faults Via Torque Monitoring in Induction Motors

Conventional diagnostic methods applied to industrial induction motors, such as the motor current signature analysis, may lead to false-negative diagnostic outcomes in several cases. Such a case consists of the nonadjacent rotor breakages occurrence. Various alternatives with advanced digital signal processing algorithms have been proposed that concern the monitoring and analysis of the stator cur...
