Abstract

This research shows the development of a hybrid method for electric faults diagnostic as stator interturn short circuit, rotor broken bar and supply unbalance voltage in three phase induction machines and squirrel cage, through a motor computational model and its operation variables. The need arises from the following shortcomings:

1. Hybrid methods for faults diagnostic that integrate the advantages of traditional methods

2. A mathematical model that instead to consider constant the motor parameters, involving its variation as a function of slip

3. A calculation method that allows the extraction of motor internal parameters without make invasive measurements.
