Researchers have developed a novel Teamwork Optimization Algorithm (TOA) that significantly improves electric vehicle (EV) motor performance by dynamically adjusting the motor’s magnetic flux in real time, a process likened to a “breathing pattern.” This innovation addresses a longstanding challenge in EV design: achieving both high energy efficiency and low torque ripple (vibrations) simultaneously. Tests demonstrate that the TOA can reduce energy consumption by up to 15%, decrease torque ripple by 40%, and lower motor stress (Total Harmonic Distortion) by 35%, all while reacting within milliseconds to changing driving conditions. Unlike previous methods, this approach requires minimal computational power and does not depend on large memory tables or complex AI systems. For everyday EV drivers, this breakthrough translates into longer driving ranges, smoother rides comparable to luxury vehicles, and reduced maintenance costs due to less motor wear. By enhancing both efficiency and comfort, the technology could help alleviate range anxiety and increase the appeal of electric cars to a broader market. Published
