Comparative Study of Energy Consumption and CO2 Emissions of Variable-Speed Electric Drives with Induction and Synchronous Reluctance Motors in Pump Units

This study carried out a comparative analysis of indicators electricity consumption and CO2 emissions for four-pole induction motors (IMs) efficiency classes IE3 IE4 with rated power 2.2–200 kW in variable speed pump unit. In addition, innovative converter-fed synchronous reluctance (SynRMs) were evaluated. The comparison was derived from the manufacturer’s specifications drive systems (PDSs) at various rotational speeds loads. results showed that emission class significantly worse compared low ratings, which make up vast majority electric service. justifies expanding mandatory range to least 7.5–200 or even 0.75–200 kW, as it will dramatically contribute achievement new ambitious goals reducing greenhouse gas emissions. operational advantages SynRMs over IMs demonstrated, such their simpler design manufacturing technology price comparable IMs.
