Problem
Addressed

Dependence on Imported Morse Motors:

Most UAV motors in India are imported, leading to high costs and supply chain vulnerabilities. This motor is entirely designed and developed in India, ensuring technological self-reliance and reducing dependency on foreign suppliers.

Unsuitability of Imported Motors for Indian Conditions: Imported motors often struggle to perform optimally in India’s tropical climate. This indigenous motor is specifically designed to handle high temperatures, humidity, and diverse environmental conditions, ensuring reliable performance across the country.

Cost Inefficiency of Foreign Technologies: Imported motors are expensive, making UAV development costly. By leveraging a low-cost rectangular PM design, this indigenous motor provides an affordable yet highperformance alternative tailored for the Indian UAV market.

Lack of Locally Adapted UAV Technologies: This motor bridges the gap by offering a solution specifically engineered for Indian UAV applications, aligning with the “Make in India” initiative to promote local manufacturing and innovation.
