The invention relates to a method for controlling a multi-phase electrical ship propulsion motor that is supplied with electric energy via a power converter. Said ship propulsion motor is preferably a permanently excited motor with at least three windings. The phase currents flowing in the windings are controlled via the power converter to minimize the body noise emitted by the electrical ship propulsion motor.

La présente invention concerne un procédé permettant de réguler un moteur électrique polyphasé de commande de bateau, qui est alimenté en énergie électrique par un convertisseur. Ce moteur de commande de bateau est de préférence conçu sous forme d'un moteur à excitation permanente comprenant au moins trois enroulements. Selon cette invention, les courants de phase qui circulent dans les enroulements sont régulés au moyen du convertisseur, afin de minimiser les bruits de structure émanant du moteur électrique de commande de bateau.
