U.S. Department of Energy efficiency standards (DOE)
Rules: Small Motor Rule (effective March 1, 2015) and Integral Motor Rule (effective June 1, 2016)
Why is the DOE requiring Commercial and Industrial Electric Motors to meet efficiency standards?
For more than three decades the efficiency of new motors has been regulated by federal law.
Nearly half of the electricity consumed in the manufacturing sector is used for powering motors and about two thirds of this machine-drive consumption occurs in the bulk chemicals, food, petroleum and coal products, primary metals, and paper industries.
The two rules that have most recently been established by the U.S. Department of Energy (DOE) are the Small Motor Rule and the Integral Motor Rule. These changes impact electric motors and will once again increase the minimum efficiency of new motors.
The updated electric motor standards apply the standards currently in place to a wider scope of electric motors, generating significant estimated energy savings. DOE‘s analyses estimate lifetime savings for electric motors purchased over the 30-year period that begins in the year of compliance with new and amended standards (2016-45). The annualized energy is equivalent to 1% of the total U.S. industrial primary electricity consumption in 2013.
Frequently asked questions
No. NEMA Premium efficient 230/460 dual volt motors are not recommended at +/- 208V voltage.
Yes. If the motor is tri voltage rated then it has a +/- 10% voltage tolerance for the stated voltages.
DOE considers 208V on a 208-230V motor an unusual condition and does not require the motor meet the efficiency over the broad voltage range.
Must meet table 12-12(NEMA Premium) at 230V and 460V.
208V requiring NEMA Premium should be 200V motor per NEMA MG1.
Commercial / end suction / multistage: In most instances, these products converted to dual voltage as standard for premium efficiency.
In case of the e-SV, we have a large offering of custom premium efficient tri-volt motors available. For motor part numbers and voltage descriptions, please check the price book for accurate descriptions of voltage offerings.
For any more not listed, or for special requests, please work with our applications / tech support team.
All commercial literature has been updated and can be found online at www.goulds.com (does not include eCOM price books).
At this time, the rules impacting the United States are not applicable to our Latin America and Canadian customers.
Efficiency rules apply but no confirmation of planned legislation to match the United States DOE regulations.
Motors built and/or imported into the U.S. must comply with DOE rules. Product built in Auburn is required to meet regulations.
Many of the new part numbers have been loaded in our system. Utilize the updated nomenclature found in the literature on www.goulds.com to configure your part number.
Part numbers that are no longer available will be marked obsolete. Obsolete part numbers have a referenced part number in the description.
Technical support / applications team is also available to help you with obtaining new part numbers.
Yes, we work daily with our motor vendors to offer you special voltages.
In general there were no significant changes to the vast majority of the motors however, if you have specific dimensional needs, please reach out to Technical / applications team for a dimensional drawing if you have specific sizing requirements.
Our dimensional information in our technical brochures and online are intended as guidelines only and are not motor specific.
No, we converted frame size to frame size. If you experience a change in frame size, please contact customer service with your part number information.
