Three-phase electric motors IE3

IEC electric motors - Three phase - IE3


These electric motors comply with IEC 60034-30-1:2004 and IE efficiency codes.

In the territory of EU since 01.01.2017 all the electric motors from 0,75kW up to 375kW should comply with energy efficiency standard IE3. This is not valid for electric motors that work with (VSDs).


IE3 three phase motors have low energy losses, greatly reduce electrical costs during their exploitation life and are characterized by low heating and longer exploitation time span. The overall and joining dimensions are in accordance with IEC 72-1 and БДС EN 50347. IE3 three phase motors can be offered in both aluminum and cast - iron construction.
