WEG has developed an online calculator that allows motor users to determine energy savings, payback times and reductions in CO₂ emissions when evaluating new projects, or replacing existing motors with higher efficiency types in fan and pump applications.

The payback calculator is not limited to WEG products: it can compare efficiencies with any product on the market. It produces reports, and can compare a wide range of variables, based on usage and component specifications, to find the best motor for an application, including multi-motor installations.
