Detroit, Michigan - Automakers likely won’t curb summer shutdowns like they have in recent years, the result of the frigid weather that swept across the U.S. in the first quarter and boosted vehicle inventory levels.
Dallas, Texas - A team from the Renewable Energy and Vehicular Technology Laboratory (REVT) at UT Dallas was one of a few research groups selected for advanced participation in a Department of Energy conference aimed at presenting the next generation of energy technologies.
The DOE’s Advanced Research Projects Agency-Energy (ARPA-E) program hosts an annual summit in Washington, D.C., for researchers, entrepreneurs, investors, corporate executives and government officials to share transformational research funded through the program.
Dr. Babak Fahimi, professor of electrical engineering in the Erik Jonsson School of Engineering and Computer Science and director of REVT, has received $2.8 million through an ARPA-E program aimed at reducing rare earth metals, which are used in motors of electric vehicles. The metals are expensive, difficult to find and are usually imported into the United States from countries such as China. In addition, the mining process for these metals releases significant amounts of pollution into the atmosphere.
While hundreds of award recipients were invited to exhibit their research, Fahimi’s team was one of five selected to demonstrate their work to lawmakers and participate in a round-table discussion on climate change.
REVT members demonstrated electric motors or generators that eliminate rare earth metals. Typical motors are powered through the electromagnetic interaction between a rotor, which contains rare earth metals and rotates, and another part known as a stator, which is stationary but houses electromagnetic sources. The REVT solution, called a double-stator switched reluctance machine (DSSRM), has two stators, one on either side of the rotor, that cause an electromagnetic reaction that produces power. This approach produces significantly greater power and torque at a given size and weight than traditional motor technologies without the use of permanent magnets.
“The transformative nature of our motor technology stems from a novel magnetic configuration, which significantly reduces the radial forces while increasing the motional forces by a factor of three,” Fahimi said. “This technology also benefits from high levels of fault tolerance, low-cost manufacturing, and low acoustic noise. I strongly believe this technology is highly appealing to automotive, oil and gas, and renewable energy industries.”
Besides delivering more power and torque than competing technologies, this machine could be manufactured entirely in the United States, which would eliminate the pollution from mining rare earth metals, while also significantly reducing the amount of air pollution released through electric vehicle emissions. Other applications of this technology are airplanes, fans, pumps, wind generators, and robots.
The research, first funded in 2012, has one patent pending. At the conference earlier this year, REVT members demonstrated the technology to potential commercial licensees.
Team members who demonstrated the technology included Pete Poorman, assistant director of corporate relations, and Drs. Wei Wang and Chenjie Lin, postdoctoral researchers in the lab.
“Having the opportunity to present at the ARPA-E Energy Innovation Summit was a huge opportunity to further our work,” Poorman said. “Being one of the few projects selected for the round-table discussion and congressional reception is both an honor and an acknowledgement of the excellent work being done in the REVT lab.”

Albany, New York – Electric Motors Market (AC motors, DC motors, Hermetic motors) is expected to reach a value of $120.68 billion by 2019, at a CAGR of 6.3% from 2013 to 2019. The demand for energy efficient electric motors is rising globally due to the introduction of stringent electricity consumption standards and rising electricity prices. In addition, rising production of motor vehicles, home appliances and other electric motor driven systems is increasing the demand for electric motors. Moreover, stringent design and manufacturing standards in designing and manufacturing to improve efficiency of electric motors are encouraging global manufacturers to develop energy efficient motors. Demand trend for electric motors is steadily shifting from standard efficiency electric motors towards high-energy efficient motors. However, lack of awareness about benefits of energy efficient electric motors and high initial purchase cost are inhibiting the growth of the energy efficient electric motors.
Based on types, electric motor is categorized into AC motors, DC motors and hermetic motors. AC motor is the largest product segment and accounted for more than 80% of the revenue share of overall electric motors market in 2012. Hermetic motor is expected to be the fastest growing segment through the estimated period. Rising demand for HVAC equipment is expected to drive this growth in the future.
Fractional horsepower (FHP) motors are most commonly used in low voltage automotive, heating, ventilating and cooling, office machinery, and several other applications. Fractional horsepower (less than 1hp) motors are used in low voltage power applications and accounted for the largest revenue share i.e. about 70% of the electric motors market by output power in 2012. However, fastest growth is expected from Integral horsepower (IHP) segment as industrial users are replacing their traditional electric motors with energy efficient motors. In addition, several incentive programs in the U.S. and European countries for early replacement of low efficient electric motors are also influencing the demand for energy efficient IHP motors from industrial sectors.
Applications of electric motors include motor vehicles, industrial machinery, HVAC equipment, aerospace and other transportation equipment, home appliances and commercial and other service industries. Motor vehicle segment is expected to remain the largest in the electric motors market. In 2012, motors vehicles accounted for more than 31% of the revenue share in the overall electric motors market by application. The sale of electric and hybrid vehicles doubled in 2012 as compared to 2011. The motor vehicle segment is expected to remain the largest application segment for electric motors due to rising demand for electric and hybrid vehicles through the estimated period. However, fastest growth is expected from HVAC equipment segment with increasing residential and commercial construction globally.
Asia-Pacific is the largest as well as the fastest growing regional market in the global electric motors market. In 2012, Asia-Pacific accounted for about 66% of the revenue share of global electric motors market. Continuous rise in production of electric motors driven systems such as motor vehicles, HVAC equipment, and household appliances in major countries including China, India, Indonesia, South Korea and Singapore is primarily contributing to the growth of electric motors in Asia-Pacific. North America and Europe are expected to see slow growth in the future. This is because several motor vehicles and electronic appliances manufacturers from these regions are shifting their manufacturing plants to countries in Asia such specially India and China.
The global electric motors industry comprises many small and large sized players worldwide. The market is highly fragmented and top five players accounted for less than 15% of the revenue share in 2012. Some major players in the global electric motors market include Baldor Electric Company Inc, AMTEK, Danaher Motion LLC, Franklin Electric Co Inc, Asmo Co Ltd, and several others.

Arlington, Texas – Texas Gov. Rick Perry and General Motors's Arlington Assembly Plant Manager Paul Graham recently attended a celebration to mark the launch of 2015 sport utility vehicles from GM’s Texas plant.
"GM has a rich heritage in Texas, building award-winning vehicles since 1954, and these new vehicles are no exception," says Graham.
"In Texas, we realize that jobs mean more than just a paycheck, they mean more opportunities to grow, better lives for families and lifelong friendships formed over the years," Gov. Perry says.
GM invested more than $500 million at Arlington Assembly to build the next generation of full-size sport utilities. Consumer demand for the all-new 2015 collection of GM SUVs is outpacing expectations. The average turn rate, or how quickly it takes a particular vehicle to sell after it is delivered to the dealer, is between 10 and 17 days for the Chevrolet Tahoe and Suburban, and the GMC Yukon and Yukon XL. The plant has also begun shipping the 2015 Cadillac Escalade to dealers.
As part of the SUV launch celebration, Graham and Gov. Perry provided General Motors Foundation grants totaling $56,000 in support of five local nonprofits as part of its annual Plant City Grants program. The organizations receiving the grants were the United Way of Tarrant County ($25,000), the Arlington ISD - Teacher Grants ($10,000), the Community Food Bank of Fort Worth($7,000), the Junior Achievement of the Chisolm Trail ($7,000) and Parents Step Ahead ($7,000).
