TSUYO EV Powertrain Technologies Launched with Gen 3.0 IPM Motor and AMT for Electric Three-Wheelers

TSUYO EV powertrain technologies were expanded on February 14, 2026, as TSUYO Manufacturing Pvt. Ltd. introduced a new portfolio aimed at electric three-wheelers and light commercial vehicles. The announcement centers on the Gen 3.0 IPM motor and controller architecture, engineered to improve thermal management, enhance durability, and simplify servicing. With a focus on performance optimization and operational reliability, TSUYO EV powertrain technologies target real-world commercial use cases where uptime, load handling, and serviceability directly influence total cost of ownership.

Gen 3.0 IPM Motor Architecture Enhances Performance

At the core of TSUYO EV powertrain technologies is the Gen 3.0 IPM motor platform. This upgraded system integrates external Hall sensors and split-phase cabling to improve control precision and electrical efficiency. An aluminium cast controller housing strengthens thermal dissipation while enhancing structural robustness for demanding duty cycles.
Additional refinements include external bootloader access for faster diagnostics and software updates, along with LED-based fault indication to streamline troubleshooting. The platform also adopts upgraded MOSFET technology to support higher-performance EV applications, reinforcing the scalability of TSUYO EV powertrain technologies across multiple vehicle categories.

Automated Manual Transmission for Electric Three-Wheelers

A major highlight of TSUYO EV powertrain technologies is what the company describes as India?s first Automated Manual Transmission for electric three-wheelers. This system is designed to enhance range, improve gradeability, and increase load-carrying capability in urban and semi-urban operations.

Improved Load Handling and Range Optimization

The Automated Manual Transmission for electric three-wheelers enables lower-power motors to manage more demanding duty cycles by optimizing torque delivery across varying gradients. By improving mechanical advantage during acceleration and hill climbs, the system supports better energy utilization and extended operational range. This advancement positions TSUYO EV powertrain technologies as a solution tailored to high-load commercial mobility segments.

SynRM Motor and Hairpin Winding Technology

The portfolio further expands with a patented SynRM motor that reduces reliance on imported rare-earth materials. By eliminating permanent magnets, the SynRM motor contributes to supply chain resilience while maintaining competitive efficiency levels for commercial electric vehicles.
Complementing this is hairpin winding technology, which is claimed to increase motor power density and overall performance by up to 20%. The adoption of rectangular conductors improves slot fill factor and thermal characteristics, strengthening the efficiency credentials of TSUYO EV powertrain technologies in high-demand applications.

Flat Tube Axle for Higher Load Capacity

Rounding out the portfolio is a flat tube axle featuring a common gear interface. This configuration is developed to enhance load capacity while simplifying parts management for L3 and Mini-L5 vehicles. By standardizing interfaces and improving structural rigidity, TSUYO EV powertrain technologies aim to reduce complexity for OEMs and fleet operators while supporting heavier payload requirements.
With integrated advancements spanning motor architecture, transmission systems, magnet-less designs, and axle innovation, TSUYO EV powertrain technologies signal a focused push toward efficiency, durability, and scalable electrified propulsion solutions for India?s commercial EV ecosystem.
