Abstract: The rapid electrification of India's four-wheeler (4W) passenger vehicle market presents unique powertrain engineering challenges, characterized by stringent cost constraints, dense urban driving conditions, and a strategic imperative to minimize reliance on imported rare-earth materials. This paper presents a comprehensive analysis of traction motor trends within the Indian electric vehicle (EV) sector, focusing on the strategic selection rationale and the resulting drivability dynamics. A critical comparative study is conducted between the currently dominant Interior Permanent Magnet Synchronous Motors (IPMSM) and the highly relevant alternative, AC Induction Motors (ACIM). Furthermore, the paper highlights how advanced dynamic control strategies specifically Field-Oriented Control (FOC) are implemented in high-power simulation environments to mitigate the inherent drivability limitations of each architecture. The findings conclude that while IPMSMs offer unmatched volumetric efficiency and low-end torque for urban commuting, ACIMs provide a vital, supply-chain-secure alternative with superior high-speed coasting dynamics. Ultimately, optimizing Indian EV powertrains requires balancing localized manufacturing capabilities with sophisticated, closed-loop motor control algorithms.
