Abstract

A drive system and method for controlling a synchronous motor having several phases, in which a method for controlling a drive system includes a synchronous motor having several phases comprises the steps: providing appropriate operating parameters for the synchronous motor by processing an input of the drive system; in case of a determination of a fault of one of the phases, calculating a zero sequence voltage for a neutral conductor based on motor parameters estimated by a parameter estimation algorithm based on detected operating parameters; and applying the calculated zero sequence voltage to the neutral conductor.
