Tula’s DMD™ Improves Electric Motor Efficiency While Reducing Rare Earth Materials in Battery Electric Vehicles \ SAN JOSE, Calif.-Tula Technology, Inc., a leader in propulsion efficiency, reported today at the International Vienna Motor Symposium that their product Dynamic Motor Drive (DMD™) mitigates efficiency losses of electric motors while significantly reducing reliance on rare-earth materials. DMD’s application to electric vehicle motors has the potential to increase range while using less energy. Improving the efficiency of the powertrain is key to reducing the energy consumed by an electric vehicle. Electric motors equipped with rare earth magnets can exceed 90% efficiency at peak performance; however, real-world driving conditions often reduce motor efficiency to approximately 70-85%, far below the peak. The patented DMD pulse density strategy mitigates efficiency losses through improvements in control software. Tula has simulated the DMD concept and projects efficiency improvements of 2.5% on the Worldwide Harmonized Light Vehicle Test Procedure (WLTP) cycle for an average electric vehicle. These improvements increase driving range while lowering total energy consumed. DMD is cost-effective, software-driven and does not require hardware changes to the motor or vehicle. Additionally, DMD avoids many of the rare earth material challenges including escalating future costs, limited supply and sourcing risks.
