Tsuyo Manufacturing, an integrated electric vehicle powertrain company, has secured two additional breakthrough motor technology patents, further strengthening its position in advanced EV systems and indigenous deep-tech innovation.
The newly granted patents include a Non-Magnetic Bridge Assisted Synchronous Reluctance Electric Motor and a Fault-Tolerant Five-Phase Interior Permanent Magnet Motor with Dual Inverter Control. These globally novel technologies are designed to enhance efficiency, reliability, scalability, and performance across electric mobility applications.
The first patent introduces a non-magnetic bridge design for synchronous reluctance motors, aimed at improving torque density, reducing energy losses, and enhancing structural strength while optimizing the use of rare-earth materials.
The second patent focuses on a fault-tolerant five-phase PMSM powered by a dual inverter system with an open-end winding configuration. The system intelligently switches between star mode for startup efficiency and delta mode for higher torque demand, ensuring improved torque control, better efficiency, and uninterrupted operation even during single-phase failures.
Commenting on the achievement, Vijay Kumar said, “These patents mark another important milestone in our mission to develop Design-in-India technologies for global EV markets. Our focus remains on creating scalable, efficient, and reliable powertrain systems that address real-world mobility challenges while strengthening India’s deep-tech capabilities.”
The innovations were developed through Tsuyo’s in-house R&D efforts in collaboration with Visvesvaraya National Institute of Technology under the guidance of Prof. Ritesh Keshari and Prof. Ramsha Sachin.
With over 29 patentable innovations, deployment of more than 300,000 powertrains, and partnerships with over 25 OEMs across on-road and off-road EV applications, Tsuyo continues to expand its footprint in India’s evolving electric mobility ecosystem.
