New motor drive design reduces heat, wear in high-power systems

US motor cuts internal voltage fluctuations by 90% for electric aircraft

Researchers at the Oak Ridge National Laboratory National Transportation Research Center have designed a new electric motor drive architecture. The system reduces internal thermal stress and slows down mechanical degradation in high-power applications. “Simulations show a 90 percent reduction in neutral-point voltage fluctuations and a 43 percent drop in current stress on capacitors, helping systems operate more reliably where durability and upt…

New motor drive design reduces heat, wear in high-power systems

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory's (ORNL) National Transportation Research Center have developed a novel electric motor drive design that meets the performance demands of aircraft, marine vessels and heavy-duty trucks while reducing excess heat and premature wear.

New electric motor design cuts heat and wear without adding extra parts

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) have developed a new electric motor drive design that could make powerful electric vehicles more reliable and longer-lasting. The new technology reduces heat, electrical interference, and wear inside motor systems without adding any extra hardware. The research could benefit large electric vehicles and […] The post New electric motor design cuts heat and wear wit…
