Mr. Ashwin Venkitaraman, an esteemed engineer and researcher based in California, USA, has conducted a comprehensive analysis on the topic of "Trends and Challenges in Electric Vehicle Motor Drivelines." The review presents a breakthrough in understanding the pros and cons of the modern-day automotive industry and sheds light on how selecting electric motors can improve drive efficiency. The research provides insights into the past and present state of the industry, as well as a detailed outlook on how the upcoming automotive industry should consider picking drive motors.
Mr. Venkitaraman's analysis focuses on the design and determination of motor execution across a broad range of speeds and powers. It highlights that while every motor has a unique torque-speed relationship, permanent magnet (PM) motors are more efficient in overload transients at a constant speed, while reluctance motors (RM) perform better under high-speed overloads. Additionally, switched reluctance (SB) motors are highly efficient across a large operating range and can operate at high speeds because of their control. The control of RMs enables high-speed operation, but at low speeds, efficiency quickly degrades. Despite being less efficient overall than PM motors, SB motors are still highly efficient, making them a cost-effective and reliable industrial use case.
The research evaluated the integration of permanent magnet synchronous motor drivelines into electric vehicle battery technology or hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) as a way to achieve the appropriate balance between the electric drive and the range-extending IC motor.
Mr. Venkitaraman's research concludes that PM motors are better than RMs, SBMs, and induction motors (IM), with IM being the least efficient in terms of performance. The cost of PM motor raw materials will ultimately decide whether PM motors become the industry standard or if RM and SBM achieve a breakthrough in the market. Overall, this analysis provides valuable insights into the trends and challenges in electric vehicle motor drivelines, and its findings are likely to have important implications for the future of the automotive industry. His research is published in the esteemed and highly rated Scopus indexed journal " International Journal of Electrical and Computer Engineering Systems ".
His findings present an exceptional contribution to the electronics industry, and his review shall make it easier for industries to thrive through the adoption of motor lines.
