Abstract :
A method is here presented that allows the diagnosis of broken rotor bars in time varying operations with simple post processing of input currents. Extensive simulations are presented to validate the proposed approach for open loop and closed loop induction machines. A diagnostic index is presented also, that is quite robust versus load and inertia variations.
