The purpose of the invention is a method for controlling a three-phase electrical machine from an inverter. Each sector of the complex representation of the space vector modulation being subdivided into three subsectors, comprising a central subsector centred on the active vector, a first lateral subsector associated with the first zero-sequence vector, and a second lateral subsector, opposite the first lateral subsector relative to the central subsector, associated with the second zero-sequence vector, it comprises a step of control of the voltage at the terminals of each phase of the electrical machine, measured relative to neutral, with the value defined by the control vector associated with the subsector in which the control vector is located.
