A system for controlling a synchronous motor drive may be configured to receive a command voltage signal and to identify, in the synchronous motor drive, a resistance imbalance signature from the command voltage signal. The system may determine, based on the resistance imbalance signature, respective phase resistances that correspond to phases of a synchronous motor of the synchronous motor drive. Each respective phase resistance may include a phase transistor resistance and a phase winding resistance. The system may identify, based on the phase resistances and an estimated average resistance between the phases of the synchronous motor, one or more phases of the synchronous motor that correspond to one or more phase resistances representing a resistance imbalance.
