Definitions
- the invention has the object, in particular to provide dynamoelectric Ma ⁇ machine that reduces even in converter of the dynamoelectric machine mainly acoustic emissions ei ⁇ ne electric machine.
- Impregnating / casting of the winding system by means of a particles impregnated resin or potting material.
- the object of reducing the noise emissions is now achieved in that the oscillatory winding systems, that is, in particular the individual wires or electrical conductors in a impregnating resin or in a
- Potting compound are embedded, which has energy-absorbed Parti ⁇ cle. This avoids that such
- the particles, especially nanoparticles, that is particles which are smaller than 100 nanometers in its extension advantageously be homogeneous within the impregnating resin angeord ⁇ net. Otherwise, these thread-like particles have a length extension of up to a few millimeters, with corresponding diameters of a few micrometers. Especially with shorter particles, the diameter can be reduced to a few nanometers.
- these particles can also be reinforced in the impregnating resin.
- FIG. 1 shows in a schematic representation an electric machine 1 with a stator 2, which in this embodiment has a laminated core 12, wherein the magnetic field-carrying part as a one-piece material, e.g. when
- Composite material can be provided.
- this magnetic field ⁇ leading material 12 substantially axially extending grooves 4 are arranged, in which the winding system 3 is housed, which forms on the front sides of the stator 2 winding heads 8.
- this rotor 9 rotates about an axis 10 and can thereby drive a working ⁇ machine via a shaft 11.
- FIG 2 thus shows in a section of the magnetic field leading mate rials ⁇ example of the laminated core 12, a groove in which a coil of the winding system is used 3 4, wherein the coil consists of a plurality of individual wires.
- the wires te 5 have distances to each other, in which the impregnating resin is filled by appropriately suitable methods, then cured to form a solid bond with the magnetic field ⁇ leading laminated core 12.
- the impregnating resin is filled by appropriately suitable methods, then cured to form a solid bond with the magnetic field ⁇ leading laminated core 12.
- particles 7 are arranged within the impregnating resin, which are designed to absorb energy.
- the ur ⁇ nally, in particular thread-like, present in the impregnating resin particles 7 are now due to a physical or chemical blend process during or after Tränkungsreaes in vibration dampening form, so as knäulartige helical or spherical structures.
- the processes used in this case can be, for example, a special heat treatment and / or a catalytically initiated process in the impregnating resin 6, which leads to an energy-absorbing shaping of the particles 7.
- the invention is not limited to the application in Ak ⁇ tiv kind of dynamoelectric machines 1, as the
- Stators and / or rotors of motors or generators limited, but is also suitable for other electrical Ma ⁇ machines, such as transformers.
- the areas corresponding thereto dynamo-electric ma- chines for example, traffic engineering, such as To ⁇ drive motors of rail vehicles and electric cars, drives in industrial technology.
