ABB Develops NEMA Energy Savings Calculator
Forty-five percent of the world’s electricity is used to power electric motors in buildings and industrial applications. By 2030, this cost is projected to reach $900 billion annually. Lowering CO₂ emissions and increasing energy efficiency is critical for our planet, but also for ensuring stable and productive industry operations, lowering operating costs and total costs of ownership. To help motor operators better understand the financial and environmental benefits of upgrading current and end-of-life industrial electric motors, ABB has developed its NEMA motors Energy Savings Calculator.
The Energy Savings Calculator is an online tool that allows users to compare the electrical energy usage, costs and CO2 production of a motor currently in operation with that of a new, highly efficient ABB Baldor-Reliance motor. The tool has two modes: basic and advanced. The basic function allows users to search existing ABB Baldor-Reliance motors by catalog number, while the advanced option has fields for motor parameters such as power, efficiency class, speed and enclosure type to allow for comparisons with any existing motor.
Both options calculate the potential energy savings that could be achieved by upgrading to a new ABB Baldor-Reliance SP4 NEMA Super Premium efficiency motor through annual savings in kilowatt hours, energy percentages and U.S. dollars are provided, as well as energy consumption comparisons between the new and existing motor and annual CO2 reduction. A digital report with data and graphics can be exported in both the basic and advanced functions. Phase 2 of the Energy Efficiency Calculator, scheduled to launch later this year, will add variable speed motor calculations, input capabilities for multiple motors and additional enhancements to the current options.
ABB Baldor-Reliance SP4 motors are highly efficient, running cooler, reducing heat-based energy losses and extending bearing and other component life. Reducing energy losses also leads to lower electrical energy consumption, which lowers operating costs and total cost of ownership. They meet current U.S. Department of Energy efficiency standards as well as anticipated Medium Electric Motor (MEM) regulations, which take effect on June 1, 2027, in the United States.
“With so much of the world’s electricity being used to power industrial electric motors, investing now in high-efficiency motors will yield immediate, significant rewards in terms of energy savings and sustainability,” said Ben Hinds, vice president of product marketing and management for ABB’s NEMA Motors Division. “ABB is committed to enabling our customers to reduce their annual emissions of CO2 by 100 megatons from 2021 to 2030 while helping them to lower their energy costs. The Energy Savings Calculator is a powerful tool to help our customers increase energy efficiency while reducing their carbon footprint.”
