SP4 General Purpose - Open motor

Baldor-Reliance® SP4 open motors deliver NEMA Super Premium® efficiency, running cooler, longer, and quieter—DOL or inverter duty—now with a 48-month warranty.

The Next Evolution in Electric Motors

Leading the way in energy efficiency yet again, Baldor-Reliance® SP4™ motors give you a path to energy savings that makes a difference to your bottom line. These motors achieve NEMA Super Premium efficiency across-the-line, independently of a drive. DOL or inverter duty, runs cooler, longer and quieter – now with a 48-month warranty.

 

The idea is simple. Take the best and proven AC induction design and make it better by reducing motor losses by an average of 20% while maintaining the simplicity of today's installed base of AC induction motors.

Explore the key features and benefits

ABB’s 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.*

Large install base

There are more than 300 million industrial motor-driven systems in operation worldwide; and roughly 80% of motors still operate DOL (direct on line).

Lower energy costs

NEMA Super Premium® (comparable to IEC’s IE4 efficiency) can offer up to 40% lower energy loss in comparison with a NEMA standard efficient (IE2) induction motor.

Cooler running

Able to achieve cooler running operation for longer life which means longer bearing life. This translates to longer motor life and industry-leading 4-year warranty.

Inverter Duty

Suitable for inverter use per NEMA MG1 Part 31.4.4.2
