THE NEXT EVOLUTION IN ELECTRIC MOTORS
Leading the way in energy efficiency yet again, ABB Baldor-Reliance SP4™ motors give you a path to energy savings that makes a difference to your bottom line. These motors achieve NEMA Premium 4 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.
WHY UPGRADE TO SP4
Why upgrade to SP4
<p>More than 300 million industrial electric motor-driven systems operate worldwide, with many still running direct-on-line (DOL). SP4 delivers higher efficiency using familiar AC induction motor technology, making it easier to upgrade existing applications.</p>Lower energy losses
<p>NEMA Premium® 4 efficiency, comparable to IEC IE4, can reduce motor energy losses by up to 40% compared with NEMA Standard Efficiency / IE2 induction motors, helping lower operating costs over the life of the motor. </p>Greater efficiency as energy costs rise
<p>As electricity prices increase, motor efficiency has a greater impact on operating expenses. SP4 helps reduce the energy required to run critical motor-driven equipment without fundamentally changing how the motor is applied. </p>Cooler operation. Longer-lasting performance.
<p>Reduced motor losses help SP4 motors run cooler, supporting longer insulation and bearing life. The growing SP4 portfolio also brings this performance to general purpose, severe-duty, pumping and HVAC applications, backed by an industry-leading 4-year warranty.</p>ABB BALDOR-RELIANCE SP4 MOTOR TECHNOLOGY
For more than a century, ABB Baldor-Reliance has helped power industry forward.
Now, SP4™ technology advances proven AC induction motor design with higher efficiency, lower losses and the same familiar simplicity.
Revolutionizing the motor industry. Again.
SP4: THE REVOLUTION CONTINUES
SP4™ brings NEMA Premium® 4 efficiency to general purpose, severe duty, HVAC and pumping applications, using familiar induction motor technology designed for practical, straightforward upgrades.
One platform. More applications. Higher efficiency.
NEMA MOTOR EFFICIENCY REGULATION HISTORY
More than 30 years of evolving U.S. motor efficiency standards have led to today’s DOE requirements, continually raising the bar for energy-efficient motor performance.
