The Baldor-Reliance Super-E
Friday, August 19th, 2011In the mid-1970s, a southeastern tire manufacturing plant asked Baldor if it were possible to increase the operating efficiencies of motors in their plants. Baldor engineers determined that considerable energy savings could be gained from a better motor design. By adding more copper to the windings, upgrading the laminations to a higher premium-grade steel, designing precision air gaps between the rotor and stator, and reducing fan losses in the motor, Baldor was able to supply the plant with the premium efficient motors it needed.
This was the birth of the Baldor Super-E®. Today’s upgraded and expanded Super-E product line offers some of the highest levels of efficiency in more than 600 stock motors rated from 1/2 to 15,000 horsepower. Super-E, severe duty, close-coupled pump, IEEE 841, washdown, and explosion-proof models are also available with a three-year warranty or better. (Our IEEE 841 motors have a five-year warranty.) Called a “key breakthrough” by the Consortium of Energy Efficiency, the Baldor Super-E was recognized by the CEE in 1998 as the first premium efficiency motor line to meet their stringent efficiency criteria citing, “For the first time, one manufacturer will carry all qualifying products.” In 2001, the CEE efficiency levels were adopted as the NEMA Premium® efficient levels and expanded to 500 horsepower.
To understand what a motor really costs, compare initial purchase price with the cost of theelectricity it uses over its working lifetime. Often, too much attention is paid to purchase price. For most motors, this initial cost represents less than two percent of its lifetime cost. Electricity accounts for about 97 percent. Baldor Electric Company’s motors and drives save customers money every minute they operate. Whether it’s lower energy costs or greater reliability, these savings go straight to the bottom line. Baldor is the industry leader in overall efficiency ratings. Better than 96 percent of the energy used by some of Baldor’s Super-E motors is converted to mechanical work. The Baldo•Reliance Super-E runs cooler and longer with greater reliability than any other industrial motor. When you consider that a typical 50 horsepower motor costs over $36,000 to operate continuously in a year, it’s easy to see how just a few percentage points of higher efficiency can quickly reduce electricity costs. Even seemingly modest percentage point differences in efficiency ratings can yield substantial electricity cost savings when the motor is operating continuously every day.
