摘要
The invention relates to a method for operating a ship drive motor (2) fed by at least one pulse width modulated inverter (3), wherein circuit elements (5) of the pulse inverter (3) are switched at a changeable switching frequency, wherein according to the invention the switching frequency is controlled manually by the operating personnel of the ship independently of the operating state of the ship drive motor (2) and the pulse inverter (3), in order to change an acoustic noise spectrum of the ship. The operating personnel of the ship can thereby selectively set a noise spectrum of the ship adapted to the requirements and conditions present at a particular time for operating the ship.
