Fault-Tolerant PMSM with Dual Inverter Control
The second patented innovation focuses on a Fault-Tolerant Five-Phase Interior Permanent Magnet Motor (PMSM), incorporating a dual inverter control system. This configuration uses an open-end winding structure that allows seamless switching between star and delta modes. Star mode improves startup efficiency, while delta mode enables higher torque output during demanding conditions. The motor is designed to maintain continuous operation even if a single phase fails, significantly enhancing system reliability. Such fault tolerance is critical in applications requiring uninterrupted performance and safety assurance.
Collaborative Development and Engineering Contribution
The development of these technologies reflects a strong collaboration between Tsuyo Manufacturing and academic expertise from Visvesvaraya National Institute of Technology in Nagpur. This partnership has enabled the integration of advanced theoretical research with practical engineering applications. By combining institutional research capabilities with industrial execution, the patents demonstrate a structured approach to innovation that supports both performance improvement and commercialization readiness within the electric mobility ecosystem.
Impact on Electric Mobility and Future Applications
These patented technologies contribute significantly to the evolution of electric powertrains by addressing efficiency, cost, and reliability challenges simultaneously. The reduction in rare-earth material dependence aligns with global sustainability goals, while the fault-tolerant PMSM design enhances safety and operational continuity. As electric vehicle adoption accelerates, such innovations are expected to play a crucial role in enabling scalable and robust drivetrain solutions across multiple vehicle segments and industrial applications.
