This paper proposes a new method, based on the analysis of the active and reactive powers of the induction motor, for the diagnosis of rotor faults in motors coupled to time-varying loads. This new method is able to discriminate the presence of a true rotor fault from a time-varying load and can be used even when both the fault and the load torque variation coexist. A theoretical analysis complemented with experimental results support the effectiveness of this new diagnostic approach for the detection of rotor faults in operating three-phase induction motors.
