Intro

By making the decision to use energy efficient
motors, you can lower your energy costs and havea positive effect on the environment. ABB’s energy
efficient motors are designed and labeled tocomply with international IEC standards and local
MEPS requirements.
MEPS (Minimum Energy Performance Standards) for low voltage
motors have played an important role in helping countries to meettheir energy efficiency and carbon dioxide emissions targets. For
motor users, MEPS have led to an overall increase in motor efficiency
and made it easier to compare efficiency levels between
manufacturers.
These benefits have prompted many countries around the world to
adopt their own MEPS. However, the actual requirements vary
between the different MEPS.
