Chennai Startup Torus Motion Unveils India's First Domestically Developed Axial Flux Motor Designed for Low-Voltage Electric Vehicle and Robotics Applications
Summary
Chennai-based Torus Motion has achieved a significant milestone by developing India's first production-ready axial flux motor for sub-100 V applications, offering a domestically engineered alternative to imported drivetrain solutions in alignment with the government's 'Make in India' and 'Aatmanirbhar Bharat' initiatives. The company's V1 and V2 motor series deliver peak power outputs ranging from 7 kW to 20 kW, catering to a broad spectrum of platforms including electric two-wheelers, three-wheelers, forklifts, autonomous guided vehicles, and industrial machinery. Compared to conventional radial flux designs, the axial flux architecture provides 50% greater compactness, superior torque density, and thermal efficiency, with peak operational efficiencies reaching up to 95%, making them particularly suited to India's demanding and diverse operating environments. The motors support flexible voltage configurations of 48 V, 60 V, and 72 V and are paired with Torus Motion's Gen 5 intelligent controllers featuring automotive-grade CAN communication and over-the-air update capabilities, ensuring seamless OEM integration and long-term reliability. Beyond commercial electric mobility, the technology is being actively explored for robotics, marine propulsion, micro tractors, and autonomous utility vehicles, signalling broad strategic and industrial applicability.
Key Takeaways
- 1. **Strategic Defence & Dual-Use Potential:** The axial flux motors' compactness, high torque density, and rugged IP67-rated protection make them viable candidates for military robotics, autonomous ground vehicles, and unmanned utility platforms used in defence logistics and border applications.
- 2. **Reducing Import Dependence:** By developing production-ready indigenous drivetrain technology, Torus Motion directly supports India's defence and strategic self-reliance goals, reducing vulnerability to foreign supply chain disruptions for critical electromechanical components.
- 3. **Autonomous and Robotics Applications:** The motors' suitability for autonomous guided vehicles and industrial robotics has direct implications for defence automation, including battlefield logistics robots, surveillance platforms, and remotely operated military equipment.
- 4. **Scalability for Military Utility Vehicles:** The V2 series' ability to power forklifts, tow tugs, and off-highway vehicles mirrors requirements for military base logistics, forward operating area support vehicles, and equipment handling in field conditions.
- 5. **Aatmanirbhar Bharat Alignment:** The development strengthens India's indigenous defence-industrial ecosystem by building domestic expertise in advanced electric propulsion — a technology increasingly central to next-generation military mobility and electrification of battlefield assets.
