1. Tsuyo was founded in 2020 with a vision to reshape the EV industry through advanced powertrain solutions. What inspired the company’s founding vision, and how has the journey evolved since then?
Ans) With over a decade of experience in the automotive industry, we have a clear vision: the manufacturing of vehicles is well-supported by a long-standing legacy of component fabrication and assembly. However, critical components such as the powertrain and power source require a transformative and innovative approach to define e-Mobility. In terms of power sources, battery production is heavily reliant on imported cells, as cell manufacturing in India is virtually non-existent. This dependency extends to countries like China, Japan, and Korea.
Regarding the powertrain, the motor and drive systems present new challenges that demand a comprehensive re-evaluation. These systems are considered key technologies within electric vehicles (EVs), crucial for delivering optimal performance and user experience. As electric motor technologies evolve, the technological advancement of EVs becomes a sustainable area where continuous innovation and engineering efforts can position any entity ahead of its competitors, provided there is a focus on consistent research and development.
With a background in engineering, particularly in metals and materials, and extensive exposure to the automotive industry, specializing in research and new product development, focusing on the powertrain sector in EVs was a natural choice. Additionally, with the rising demand and adoption of EVs, many core technologies—such as motors, controllers, and drivetrains—remain largely imported.
For India’s EV ecosystem to achieve sustainable and scalable growth, it is essential to develop these technologies domestically. Given the unique geographical conditions, driving behaviors, and duty cycles in India, there is an urgent need to create solutions tailored specifically for Indian OEMs. These solutions must address specific vehicle requirements and conditions, which cannot be sustainably achieved through the use of standard SKUs imported or offered by foreign companies, as these are developed with other countries’ conditions in mind. This realization led to the establishment of Tsuyo. Our objective is to deliver reliable, high-performance powertrain solutions that are both designed and manufactured in India, thereby supporting OEMs in their transition to electric mobility.

Scalable powertrain technology is instrumental in facilitating electrification across a broader spectrum of mobility and industrial applications.
4. Your solutions cater to both on-road and off-road applications. How do you approach engineering solutions for such diverse use cases?
Ans) When designing powertrain systems, our starting point is always a rigorous analysis of the real‑world application profile and the duty cycle specific to the geography and operating environment. Vehicles across segments—from light urban mobility to heavy off‑highway machinery—exhibit vastly different load spectra, transient behaviors, and thermal constraints.
On‑road3W/4W vehicles:
These typically require compliance with IEC S9 duty cycles, characterized by highly dynamic load variations, frequent acceleration/deceleration, and regenerative braking events. The engineering focus here is on:
- High efficiency motors with optimized electromagnetic design (slot/pole combinations, winding topologies).
- Compact packaging to minimize weight and maximize volumetric power density.
- Advanced cooling strategies such as liquid jacket cooling or integrated heat pipes to manage transient thermal spikes.
- Inverter design with wide‑bandgap semiconductors (SiC/GaN) for fast switching and reduced losses.
Tractors and construction machinery:
These operate under constant torque and constant power duty cycles, often at low speeds but with sustained heavy loads. The engineering priorities shift toward:
- High‑torque motors with reinforced rotor structures and higher thermal mass.
- Continuous operation efficiency in the constant torque region, ensuring minimal copper and iron losses.
- Robust drivetrains with gear reduction stages optimized for mechanical shock loads.
- Enhanced cooling systems (forced liquid cooling, oil‑spray cooling) to sustain long‑duration operation under high ambient temperatures.
Engineering Approach
Our methodology is application‑driven customization, where each subsystem is tailored to the performance envelope of the target vehicle:
- Motor Design: Selection of topology (PMSM, SRM, induction) based on torque ripple tolerance, efficiency targets, and cost constraints.
- Cooling Systems: From passive finned housings for light EVs to closed‑loop liquid cooling with integrated chillers for heavy machinery.
- Drivetrain Components: Gear ratios, bearing selection, and lubrication systems are optimized for load cycles and terrain conditions.
- Power Electronics: Inverter and DC/DC converter architectures are tuned for switching frequency, EMI compliance, and thermal robustness.
Environmental Robustness
Given the diversity of operating environments—high ambient temperatures, dusty terrains, water ingress, and mechanical vibrations—our systems are engineered with:
- IP67/IP69K protection levels for enclosures.
- Redundant thermal management sensors for predictive derating.
- FEA for structural integrity under shock loads.
- Advanced control algorithms (field‑oriented control, torque vectoring) to ensure stable performance across variable conditions.
This technical framing highlights not just the application differences but also the specific engineering levers—motor topology, cooling architecture, drivetrain robustness, and electronics design—that are tuned to deliver optimal performance across diverse duty cycles.
