Super-E Motors
Industrial electric motors represent the single largest end use of electricity in the United States. The Department of Energy estimates that 25 percent of the electricity sold in the US is consumed by industrial electric motors. In addition, 64 percent of the energy used in industry is consumed by motorized equipment. These motors are used to power production processes and heating, cooling and ventilation systems.Improvements to the efficiency of motorized equipment can therefore result in a significant impact to the overall profitability of manufacturing plants.
We understand the impact of electric motor energy efficiency to the "bottom line". Many years ago in 1983, we debuted the premium efficient Super-E motor line, an industry first. Since then we have maintained the lead in providing the most energy efficient electric motors and drives in the industry.

The pie chart to the left shows the typical life cycle cost of a 100 Hp motor operating in continuous duty over a 20-year life. As you can see, the original purchase price is almost insignificant compared to what it will cost to power the motor during its useful life.

The Baldor Motor line is being upgraded to meet the energy efficiency requirements of the Energy Independence and Security Act of 2007 (“EISA”). Under EISA, all general purpose motors, from 1 to 200 horsepower, manufactured in the United States after December 19, 2010, must meet higher efficiency levels.
Baldor will offer customers two broad lines of energy-efficient motors in response the EISA:
- Compliance for General-purpose Subtype I motors will be by our Super-E family of motors that meet or exceed NEMA Premium® efficiency levels of NEMA MG1, table 12-12.
- The efficiency for 1-200 HP Subtype II motors and the 201-500 HP motors will be met by Baldor’s Standard-E motors; providing efficiency levels compliant with the requirements. Efficiency levels will be adjusted on some motors to meet EISA levels of NEMA MG1, table 12-11. Super-E NEMA Premium® efficient motors are available for these ratings that exceed EISA requirements for companies wishing to save on electrical costs.

Savings using a 40-horsepower Baldor Super-E® - 94.5% efficiency
Compared with an average industrial motor - 88% efficiency.- Electricity accounts for nearly 98% of the lifetime cost of electric motors.
- A 30-horsepower Baldor Super-E motor can save more than $1200 per year during continuous use.
- Baldor Super-E motors have more copper in the windings, premium-grade steel laminations, precision air gaps and reduced fan losses compared to standard motors.
- Baldor was cited by the Consortium for Energy Efficiency for the Super-E motor line, as the first manufacturer carrying all qualifying products that meet efficiency criteria and exceeds EPA standards.
- Chemical processing, close-coupled pump and explosion-proof models available.
-
Payback is the time in months it takes for the cumulative energy savings to equal the full cost of a new
Super-E® motor. Payback varies depending on motor use.
- Payback can occur in less than a year depending on motor size.
- Modest efficiency ratings yield substantial energy savings.
- DOE recommends applications and processing improvements. The right combination of Baldor Super-E motors and adjustable speed drives can yield savings up to 50 percent.
- Baldor Save+ software compares operating costs, summarizes annual savings and calculates payback time based on individual operation.
- Energy savings continue to accumulate during the life of the motor.
-
The efficiency level of Baldor motors exceeds the level of the average installed Motor base.
- Depending on horsepower, Baldor Super-E® motors can reduce electricity use by up to 9%.
- Standard three-year warranty. Exceeds EPAct standards.
- Initial purchase price represents less than three percent of the lifetime cost of a motor. Electricity usage represents the remaining percentage, thus efficiency is critical to long-term economical operation.
- Fits requirements contributing to rebates or incentives offered by more than 30 utilities in the U.S.
- Installing proper drives increases savings potential.
