Electric Motors
Electric motors are found everywhere in commercial facilities and industrial plants, where they power fans, pumps, compressors and exhausts as well as manufacturing and assembly equipment. Electrical energy consumption can be greatly reduced by replacing older, worn out motors with energy-efficient equivalents and specifying energy efficient motors in new equipment. Such practices not only lower energy costs but also improve equipment reliability.

Energy Independence and Security Act
Dr. Edwin Brush explains the Energy Independence and Security Act as it pertains to electric motors. NEMA Premium is the minimum efficiency standard in most cases.- Motor Loss Categories
Dr. Edwin Brush of BBF and Associates explains the loss categories in an electric motor using a motor cutaway. - Above-NEMA Premium Motors
Explanation of motors that exceed NEMA Premium efficiency, particularly cast copper rotor motors. Each of the losses categories is explained, and how each is reduced. - Benefits of NEMA Premium
Randy Breaux explains that these motors run cooler than standard motors, can improve up-time. - NEMA Premium vs. Above-NEMA Premium Motors
Super premium motors, some featuring a cast copper rotor, are available that offer even lower losses than NEMA Premium, exceed the minimum efficiency required and save even more. - Replace Rather Than Rewind
When a motor fails, that’s the ideal time to consider a more efficient replacement. Rewinding an older, inefficient motor only produces a rewound inefficient motor. - IEEE 841 Electric Motors
An explanation of IEEE 841 industrial duty motors relative to standard NEMA Premium motors.
Education
- Copper Motor Rotors
Super premium motors are now available. - Introduction to Premium Efficiency Motors
This article describes the several loss categories in motors, how premium efficiency motors reduce these losses, and shows several tables with purchase and operating cost comparisons, as well as paybacks available when selecting premium efficiency motors as replacements for, or in place of standard models. - Go Beyond Minimum Requirements: NEMA Premium ® Motors Mean Big Savings, Fast Payback and Higher Reliability
This article explains reasons why you want to consider Premium Efficiency Motor and contains several examples of energy and dollar savings available with NEMA Premium ® Motors. - A Systems Approach to Calculating Energy Savings
This section will help you calculate the best, most efficient designations for wiring, motors and transformers. - MotorSlide Calculator™
A sliderule tool for quickly approximating the annual operating cost of a specific electric motor, or for calculating the approximate annual savings possible when comparing a more efficient motor versus another, less efficient model of comparable size. The calculator also has a built-in table of NEMA Premium ® nominal efficiencies versus EPAct minimums (up to 200 hp), for quick reference.

- Mineral Producer Installing 150 Copper-Rotor Motors Rising Energy Costs Drive Upgrades, Rapid Payback Expected
This New York State mining concern decided to fight increasing utility charges by going beyond premium motor efficiency, long before the law required the change. 150 new cast copper rotor motors are being installed in place of both NEMA Premium and EPAct-efficiency motors. - Copper-Rotor Motors + Variable Frequency Drives Maximize Savings at a Brass Mill
This summary describes the results of a copper-rotor motor evaluation program undertaken by the New York State Energy Research and Development Authority (NYSERDA) at the Rome, New York, brass mill of Revere Copper Products, Inc. - Copper-Rotor Motors + Variable Frequency Drives Maximize Savings at Water Treatment Plant
This summary describes the results of a copper-rotor motor evaluation program undertaken by the New York State Energy Research and Development Authority (NYSERDA) at the Albany County Sewage District’s (ASCD) North Plant in Menands, New York. - Motor Upgrades Help Cut HVAC Energy Costs at Emory University
A combination of a sound motor replace/repair policy along with a sophisticated monitoring system have contributed to large operating savings at this prestigious university. - Kodak Focuses on NEMA Premium®
Photo giant's Total Motor Program saves at least $250,000 per year by installing high efficiency motors whenever possible, irrespective of size. - Skating Arena Cuts Energy Costs with Premium-Efficiency Motors
Despite only a 28% duty cycle, new NEMA Premium® motors paid back their purchase price in only 4 months. - Brass Mill Cuts Costs with NEMA Premium® Motors
At one of the nation's largest brass mill, if a 50-hp (or smaller) motor fails, it's replaced with NEMA Premium. If it's larger and the cost of a repair or rewind is 50% or more of a replacement, a new motor is purchased. That policy is ensuring 18-month, or less, payback for Outokumpu Copper Products. See how this motor plan, along with copper-wound transformers, can help your company. - Cummins Engine Company Saves $200,000 per Year With 800 Energy-Efficient Motors
Experience shows improved motors produce huge savings and fast paybacks.
