SINAMICS Inverters for Single-Axis Drives: Expansion of power loss data to include partial-load operation

  • Entry
  • Associated product(s)
Energy efficiency and losses data of SINAMICS frequency converters according the European ecodesign recommendation EN 50598.

Update: 03/08/2019

The European guideline series EN 50598.defines the ecodesign requirements for low voltage drive systems based on a combination of electrical motor and frequency converter.

The aim of this recommendation is to achieve a more sustainable energy industry in the EU and to get reasonable indicators for comparing the energy efficiency of an electrical drive system including a frequency converter.

With these indicators it becomes possible to compare drive systems not just related to their rated power, but in detail also based on the given application scenario and also in terms of optimal interaction between motor and frequency converter.

The scope of the recommendation comprises variable speed drives according the following criteria:

  • AC/AC-converters without regenerative feedback function
  • Motors with integrated frequency converter
  • Line voltage supply in the range of 100 V to 1000 V
  • Power range 0,12 kW up to 1000 kW
