About 45% of the world’s electricity is converted by electric motors into motion, and there are more than 300 million industrial electric-driven systems in operations worldwide. The ABB Baldor-Reliance SP4 motors were developed to progress toward a more sustainable and efficient future driven by the need to reduce energy consumption. SP4 technology meets the NEMA Super Premium efficiency level in a standard AC induction motor design operating across the line, independently of a variable speed drive.

The idea is simple: take a proven AC induction motor design and make it better by reducing motor losses bySource: ABB Motors & Drives an average of 20% while maintaining the simplicity, form, fit and function of today‘s installed base of AC induction motors. With more than 80% of industrial electric motors operating direct on-line (DOL) — without using a drive to improve efficiency — SP4 represents ABB’s commitment to improving efficiency and performance without needing design engineers to make significant investments in additional technology or components. As a standalone DOL unit, SP4 achieves NEMA Super Premium efficiency; however, when paired with a variable speed drive, even higher efficiency levels are attainable.

SP4 motors are highly efficient, run cooler, reduce heat-based energy losses, and extend bearing and other component life. Reducing energy losses also leads to lower electrical energy consumption, which lowers operating costs and total cost of ownership.
