This paper investigates the effect of different asymmetries on the results of the usual self-commissioning procedures for induction drives, as well as the further possibilities given by a digitally controlled inverter. It is shown that, even at a standstill, it is possible to detect some fault conditions of the machine. In particular, a specific supply scheme is proposed that, through the machine response, allows outlining the rotor conditions. This technique implements the IEEE Standards single-phase rotor test on a DSP-controlled converter, allowing the detection and the quantification of the rotor fault conditions. © 2010 IEEE.
