High Power Density DC Motor

HELI's motor product adopts high slot full rate winding technology and high-quality rare earth magnetic steel, combined with precision machining technology, to increase its power density by more than 30% compared to traditional motors, while maintaining ultra-high energy efficiency of over 90%.
Each model undergoes fatigue testing before being finalized, running continuously for over 3000 hours without any malfunctions, confirming its excellent reliability and environmental adaptability.
We provide a full range of standardized solutions from low power to high power, supporting rapid customization and development, providing lightweight and efficient power centers for underwater robots, propulsion systems, and other equipment, helping customers achieve more durable and flexible deep-sea operation capabilities.

High power density DC motor has been widely used in the power system of high-end fields such as underwater thruster of manned deep-sea submersibles, military submersibles, and underwater vehicles, whether it's ROV thruster or AUV thruster, it all can provide excellent power, driving the boundaries of ocean exploration and development to constantly expand. At present, our company's clients have covered various countries around the world, Latin America, Europe, Australia, Asia

HELI has a R&D team led by senior motor experts, who possess core technologies from electromagnetic simulation, thermodynamic analysis to control algorithm development. With advanced simulation platforms and independent intellectual property design systems, they can quickly complete the entire process of development from conceptual design to prototype verification.
In the production and manufacturing process, we are equipped with precision manufacturing equipment such as vacuum coating equipment and robot assembly lines, achieving 100% digital control of key processes to ensure product consistency and reliability.
The testing and verification system covers a professional laboratory of 2000 square meters, equipped with a complete set of testing equipment such as high and low temperature wet heat test chambers, deep-sea pressure simulation chambers, vibration impact tables, etc. Each motor needs to pass 28 rigorous tests including 72 hours of full load aging, 1000 meter water pressure testing, and EMC anti-interference testing.

With this complete "research and development manufacturing testing" closed-loop system, we have delivered reliable high-performance motor products to global customers and become a trusted partner for deep-sea equipment power systems... Read More
