A method of operation is provided during which an electric motor of an aircraft is powered using a power supply. The power supply includes a plurality of power strings electrically coupled in parallel. The powering includes: outputting string electricity from each of the power strings; and outputting supply electricity from the power supply. A plurality of string parameters are measured using a sensor system.
