When operating most vehicles, it is often the goal to reduce loud noise or even to avoid it.
- the invention has for its object to ensure the quietest possible operation of an electric machine or to provide a vehicle, especially a submarine, with such a quiet electric machine.
- the object is achieved by a method for operating an electrical machine, which is particularly intended for driving vehicles, in particular of submarines, comprising a stator having a plurality of coils, as well as a plurality of converters for supplying power to the coils by a first group of inverters into the associated coils with a respective phase offset, a first current having a fundamental with superimposed harmonics is fed in and, at the same time, a second group of inverters in the associated coils, a second with respect to the harmonics of the first Current modifi ⁇ ed, in particular inverted stream is fed.
- an electric machine which is provided in particular for driving Fahr ⁇ witnesses, especially of submarines, comprising a stator having a plurality of coils, a plurality of inverters for supplying power to the coils, and a control device for that is arranged to operate a first group of inverters for feeding into the associated coils with a respective phase offset from a first current, the first current having a fundamental with superimposed harmonics, and at the same time a second group of inverters for feeding a second one to operate in relation to the harmonics of the first current, in particular inverted current to operate in the associated coils.
- the object is finally achieved according to the invention by a vehicle, in particular submarine, with such an electric machine.
- the advantages and preferred embodiments set out below with regard to the method can be transferred analogously to the electric machine and the vehicle.
- the invention is based on the idea of generating by a counter clocking of the second group of coils an active Geisseschkompensa ⁇ tion.
- the noise is usually generated in the coils, which are supplied with the first current by the first group of converters, which are intended for the operation of the electric machine for generating anew fresh torque.
- the inverters of the first group feed the first current into the respective coils with a respective phase offset.
- the second group of inverters represents inverters that are not required for normal operation or a partial load operation of the electrical ⁇ rule engine. According to the invention, these inverters are used in order to supply current, in particular with the same frequency response, to the coils which energize them, but with one to the harmonics of the first one
- modified stream is understood to mean that the second stream is modified based on the first current, so that for a desired period of a counter clock for example, by a reversal of the current signal
- the amplitude of the differential clocking is not necessarily the same as that of the harmonics of the first group
- the course of the second current may be modified by a factor, wherein the factor may be variable in time, ie the modification is not continuous or closed Different periods of time are differently modified
- Group of inverters means a number of one, two or multiple drive is understood to be controlled in the same.
- a spatial proximity of the inverter inner ⁇ half of the group is advantageous, but not a mandatory requirement, that is, the group is not the spatial distribution ⁇ distribution of the inverter, but defined by their function.
- the active noise cancellation (Engl. Active Noise Reduction (ANR) or Active Noise Cancellation (ANC)) is known and industrial applications such as in active exhaust noise ⁇ absorbers for motor vehicles.
- the principle is based on the He ⁇ generation of sound to extinguish a disturbing sound using destructive interference. For this purpose, a signal is generated which corresponds exactly to the interfering sound of opposite polarity.
- sensors are mounted on the lineup to calm the excited motor structure, which first pick up the background noise and then apply phase-canceled eradication signals by means of actuators.
- He ⁇ follow below 1 kHz since about the synchronous phase shift can not be built quickly enough.
- the timing of the active coils engaged by the first group of inverters is known, and therefore the current parameters need not be determined. This eliminates a Re ⁇ chenakukanakukane and the Gegentaktung is more precise and faster already at the noise source.
- the second current is generated in a normal operation or a partial load operation of the electric ⁇ machine because not all converters are required for the torque generation.
- Such Geöschkom- is particularly advantageous pensation especially in a quiet crawl speed ei ⁇ nes submarine because corresponds not necessarily the full power of the electric motor in this case, is divisive, but the primary goal is to operate the drive of the submarine particularly quiet.
- the first group of inverters and the second group of inverters are used to generate an electrical torque in the electrical machine.
- the coils energized by the second group of inverters are no longer used to generate counter-noise, but in full-load operation these coils, as well as the coils of the first group of inverters, are used to operate the electrical machine , so that a particularly high performance of the electric machine is achieved.

- Under machine housing here is a housing of the electric machine understood, which encloses both a rotor and the stator.
- the outer converter are preferably gela ⁇ siege as close as possible to the machine housing, in particular on the machine housing.
- the outer environmental rectifiers are in particular those which are not required for normal Be ⁇ operating the electrical machine. They are therefore preferably added only in full load mode of the electric machine to the internal converters or they are used with regard to a particularly quiet operation of the electric machine (eg creeping a driven by the electric motor submarine) for active sound compensation.
- the electrical machine inverter not all required for the operation of the electrical machine inverter are arranged inside the rotor, but a number of inverters is outside the rotor, but as close as possible to store the electric machine.
