High efficiency low voltage motors

Reference: F.1.1

LEME Mitigation

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

Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)

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.
