Abstract
The effects of load level on the ability to diagnose broken bar faults in squirrel cage induction motors are studied in this paper. The pendulous oscillation of the rotor magnetic field orientation is implemented as a fault signature for rotor fault diagnostic purposes. Moreover, the effects of load level on the low side band component of the stator current spectrum are reported as well. These investigations were performed through testing 2-hp and 5-hp induction motors over a wide range of load levels and control-drives. The results of these tests and investigations demonstrate that the pendulous oscillation signature can be used for a wide range of motor operating conditions.
