Claims (4)

1. Umrichter zur Leistungsregelung eines mittels eines Wechsel- oder Drehstrommotors angetriebenen Aggregates, wie einer Pumpe oder einer Verdichters, bspw. eines Seitenkanalverdichters, wobei in oder nach dem Frequenz umrichter eine Messung des elektrischen Stroms erfolgt, dadurch gekennzeichnet , daß der Frequenzumrichter ein Speicherelement aufweist, in welchem ein Zusammenhang zwischen der Stromstärke und der Frequenz bzw. der elektrischen Leistung und der Frequenz niedergelegt ist. 1. inverter for controlling the power of a driven by an alternating or three-phase motor unit, such as a pump or a compressor, for example. A side channel compressor, which takes place in or after the frequency converter, a measurement of the electric current, characterized in that the frequency converter comprises a memory element in which a relationship between the current and the frequency or the electric power and the frequency is set forth.
2. Umrichter nach Anspruch 1 oder insbesondere danach, dadurch gekennzeichnet, daß der Speicher ein EPROM oder ein EEPROM ist. 2. Converter according to claim 1 or in particular according thereto, characterized in that the memory is an EPROM or an EEPROM.
3. Umrichter nach Anspruch 1 oder 2 oder insbesondere danach, dadurch gekennzeichnet, daß in dem Speicher ein Zusammenhang zwischen dem elektrischen Strom oder der elektrischen Leistung und der Frequenz bezüglich eines ausgewählten Parameters des Aggregates, wie bspw. der Druckdifferenz oder dem Volumenstrom bzw. dem Massen strom, niedergelegt ist. 3. Converter according to claim 1 or 2 or in particular according thereto, characterized in that in said memory a relationship between the electric current or the electric power and the frequency with respect to a selected parameter of the unit, such as, the pressure difference or the volume flow or the current masses, has resigned.
4. Umrichter nach einem der Ansprüche 1 bis 3 oder insbesondere danach, dadurch gekennzeichnet, daß in dem Speicher Grenzwerte in Abhängigkeit einer maximal zuläs sigen Temperatur und der Frequenz niedergelegt sind. 4. Converter according to one of claims 1 to 3 or in particular according thereto, characterized in that laid down in the memory limits in dependence on a maximum zuläs sigen temperature and frequency.
