The **T40-DISCO-ROCIADOR-SUPER** refers to the high-performance centrifugal sprinkler (atomizer) disk assembly used in the **DJI Agras T40** agricultural drone. Unlike traditional pressure nozzles, this system uses high-speed rotation to atomize liquid into fine droplets. --- ## 🛠️ Core Electronic & Mechanical Components The "Super" variant of the T40 sprinkler system integrates several sophisticated electronic parts to ensure precision spraying: ### 1. High-Torque Brushless Motor The heart of the assembly is a specialized brushless DC (BLDC) motor. * **Function:** Spins the atomizing disk at speeds ranging from 8,000 to 16,000 RPM. * **Control:** Regulated by the drone's ESC (Electronic Speed Controller) to adjust droplet size (VMD) in real-time via the remote controller. ### 2. Centrifugal Atomization Disk While the disk itself is mechanical, its design is critical to the electronic load management. * **Structure:** Features a dual-layer serrated edge. * **Electronic Interaction:** The motor's sensors monitor the resistance on the disk to maintain constant RPM even as liquid density or flow rate changes. ### 3. Integrated ESC (Electronic Speed Controller) Usually located within the arm or the motor housing base. * **Communication:** Uses a digital bus to communicate with the Flight Controller. * **Feedback:** Provides telemetry on motor temperature, current draw, and rotation speed to prevent burnout if the disk becomes jammed by debris. --- ## 📊 Technical Specifications | Component | Specification | | :--- | :--- | | **Motor Type** | High-speed Brushless (BLDC) | | **Droplet Size Range** | 50 - 500 μm (Adjustable) | | **Max Rotation Speed** | ~16,000 RPM | | **Cooling System** | Passive air-cooling via integrated fins | | **Connection Interface** | Multi-pin waterproof quick-connector | --- ## 💡 Key Electronic Features ### Constant Flow Control The system works in tandem with the **Electromagnetic Exhaust Valve** and the **Impeller Pump**. The electronics ensure that the motor speed of the sprinkler matches the pump's flow rate to prevent "dripping" and ensure uniform coverage. ### Protection Circuitry The "Super" assembly includes sensors to detect: * **Stalling:** If a branch or thick chemical residue stops the disk, the power is cut to save the motor. * **Overheating:** Automatic throttling if the motor reaches critical temperatures during high-ambient-heat operations. ### Quick-Release Interface The electronic connection uses gold-plated pins designed for high-current transmission and corrosion resistance against harsh pesticides. ---
