|
Fields of application
|
|
|
Controlled three-phase drives with frequency inverter for printmachines, wood/plastic-machines, textile machines, packing machines, tool machines, production robots, conveyor belts, cranes, railway and transport, grinding mills, mixers, pumping aparatus, fans and chemical industries, test equipment, wind powerplants and photovoltaic system.

Description
|
|
|
Reactor with capacitor for sine wave creation of the output current of a frequency drive. Longer lifetime of motor insulation with reduction of du/dt and noise reduction. Motors can be operated over long supply lines, in most cases a screened cable is not necessary, better EMC data.
|
|
|
Advantages of cut-cores compared to normal metal sheets in sinusoidal filters
|
|
- higher harmonics possible (8 kHz instead of 4 kHz)
- lower hum noise due to lower magnetostriction
- thin tape material possible, thus loss optimised
- generally lower losses compared to metal sheets
- magnetic flux along the tape windings
- smaller air gap due to tape winding
- optimal distribution of the necessary choke air gaps due to a free choice of cuts
- more than one air gap possible
- nano crystalline material available
- higher efficiency
- no holes that would disturb the magnetic flux
