Tula Technology presents findings on its Dynamic Motor Drive at the 42nd International Vienna Motor Symposium Tula Technology, Inc., the developer of Dynamic Skip Fire (DSF) and diesel DSF cylinder deactivation technology for combustion engines, reported at the International Vienna Motor Symposium that its product Dynamic Motor Drive (DMD) (earlier post) 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. 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.
