The efficiency classes according to CEMEP/EU specifications are
illustrated below. There are 3 efficiency classes, with only motors
> 1.1 kW taken into account. The ultimate objective is to remove
EFF-3 motors from the market and replace them by EFF-2 motors,
better still by EFF-1 motors. Using ebm-papst products helps to
exceed these voluntary agreements:
EC fans and motors even surpass the specifications for EFF 1.
Even the "Nema-Premium" limit as defined by the American
NEMA (National Electrical Manufacturers Association) is something
EC motor technology easily meets and even exceeds considerably
for each speed. And this with integrated control system!
