Reference: F.1.1
Replace existing motors by efficient motor
For electrical motors with a high annual duration of functioning (for example more than 3000 hours per year)
P> 7,5 kW : mini IE3 Premium efficiency class criteria P<7,5 kW, mini IE2 High efficiency class criteria
Standard IEC 60034-30 2009
Medium/long term
Reduce electricity consumption by replacing electrical motors and implenting VSD (if useful) : energy saving : replacing IE2 with IE3 : up to 20 % for small size motors, up to 10 % for medium size ; implementing VSD : energy saving : depends of the use : up to 30 % in best cases.
