Ultimo - IE4 Motors


IE4 motors, also known as Super Premium Efficiency Motors, are built around standard 3-phase motors using special materials. They are suitable for a range of applications. IE4 motors from LHP are developed in accordance with energy-saving guidelines from IEC (IEC/ EN 60034-30-1:2014) and approved by BIS as per the latest IS 12615. By using IE4 motors from LHP, one can save significant energy, reduce operating costs and carbon emissions to meet the pollution norms. IE4 motors operate two efficiency bands above IE3 motors, which is equivalent to almost 20% reduction in energy losses. They are recommended where motors operate almost continuously at full load.
