The invention relates to a method for operating an electrical machine (2), especially for driving vehicles, in particular submarines. Said electrical machine (2) comprises a stator having a plurality of coils, and a plurality of converters (10a, 10b) for supplying current to the coils. In order to reduce noise when the electrical machine is operated a first current (I1) having a fundamental oscillation (G) with superimposed harmonic components (O) is supplied to the coils with a respective phase offset by means of a first group of converters (10a) associated therewith, and at the same time a second current (I2), which is modified, particularly inverted, with respect to the harmonic components (O) of the first current (I1), is supplied to the coils by means of a second group of converters (10b) associated therewith.
