III. Structure and Core Features
- High-Power-Density Thermal Design
- Featuring a large‑size stator with an 83 mm diameter and 18 mm thickness, paired with high‑diameter oxygen‑free copper windings, this design significantly enhances thermal dissipation and power density, enabling sustained heavy‑load operation and meeting the demanding long‑duration requirements of agricultural spraying drones.
- High-Voltage Compatibility and High-Efficiency Energy Saving
- It supports high‑voltage batteries up to 14S, reducing the number of battery strings in multi‑motor systems, simplifying power management, and lowering wiring losses to improve overall vehicle range efficiency.
- High reliability and durability
- Equipped with imported EZO high-speed bearings, it reduces friction losses at high speeds, extends motor life, and minimizes vibration. Key windings are hand-wound to enhance coil uniformity and insulation reliability, ensuring compatibility with the harsh operating conditions of agricultural drones.
- Lightweight, high-strength fuselage
- A high-strength aluminum alloy housing balances rigidity and lightweight design, reducing the drone’s dead weight and enhancing its overall thrust-to-weight ratio and payload capacity.
IV. Typical Application Scenarios
- Agricultural plant protection drones: 10–20 L‑class multirotor sprayers (e.g., 6‑rotor or 8‑rotor models)
- Heavy‑Load Logistics Drone: Power System for High‑Payload Cargo Transport and Inspection Drones
- Industrial-grade multirotor platform: ideal for applications requiring high thrust, such as surveying and mapping, security, and large-scale model aircraft.
