High Spray Efficiency Fumigation UAV Agricultural Spraying Drone by Leading China Suppliers and Factory for Coffee and Crop Care
Advantages and features of product accessories
1. Motor and ESC
- Brand-new motor, with greater power redundancy and greatly improved power output.
- Adopting 3 bearings, the durability and drop resistance are greatly improved. Fully waterproof structure, specially designed for plant protection.
- Adopting 40/43 inch nylon blades, the flight efficiency is better and the unit flight time is longer. (20L full load hovering time reaches the industry's high level)
- Adopting self-developed integrated FOC ESC, the adjustment is more precise, energy consumption is reduced, efficiency is improved, and flight time is longer.
- The motor and ESC connection adopts automotive-grade plug, which has better waterproof performance, less heat generation, and better heat dissipation performance.
- Self-designed frame + self-developed power system, the aircraft has high coordination, strong coordination, fast response speed, and higher operating efficiency.
2. Power distribution board
- Intelligent power distribution board design, integrating anti-ignition, power monitoring, data recording, CAN communication and other functions.
- Flat-laying ESC structure on the tube, higher heat dissipation efficiency.
- ESC has fault storage function, accurately locates the cause of the fault.
- Rated current 200A, peak current 400A (20 kg full load flight hovering current is about 140A, 30 catties full load flight hovering current is about 170A).
3. Wire
- The wire adopts automotive grade plug, which is more waterproof and can withstand higher current.
- Customized wire, more reasonable and beautiful wiring.
4. Adaptation
- The flight control installation area is larger, which can be adapted to multiple flight control.
- Add a dust cover, which has better waterproof and dustproof performance.
- It can be adapted to multiple batteries.
