Presenting our groundbreaking self-developed external rotor motor, crafted with an advanced IMU configuration. This innovative design merges the ESC active control strategy with a coordinated regenerative braking strategy, ensuring large torque and permanent magnet synchronization. Experience an unprecedented level of integration that significantly elevates reliability and enhances transmission efficiency.
Whether it's torque recovery or any auxiliary braking within the peak torque spectrum, our system delivers flawlessly. Embracing aluminum alloy materials in several components, we've realized a lightweight marvel that maintains the highest standards of performance.
Smart Controller:
1. A marvel of engineering, the fully enclosed smart controller boasts an IP66 protection grade. It stands impervious to dust, water, and moisture, and excels in high-temperature environments, making it ideal for both indoor and outdoor applications.
2. Featuring a no-position vector control system, it is resilient against electromagnetic interference and radiation. Its compact size and lightweight design, coupled with a sleek appearance, render it both functional and aesthetically pleasing.
3. Simplicity is paramount. The system's straightforward function with four-button operation (start, stop, speed up, slow down) ensures user-friendly interactions.
4. Equipped with comprehensive protections, our system guards against overvoltage, undervoltage, voltage loss, current irregularities, phase deficiencies, overload, collisions, overheating, lightning, and any abnormalities, safeguarding your operations.
5. Customize the intelligent control mode to tailor the system precisely to your needs.
Fan Blade: Crafted from high-strength aluminum-magnesium alloy, used in aviation, our fan blades undergo extrusion and stretching processes. Internally reinforced wings offer high strength, excellent toughness, and minimal weight, ensuring a long service life and safety. Enhanced with T5 plus surface bright oxidation treatment, these blades exhibit superior corrosion and oxidation resistance, perfectly suited for challenging environments.
Tail:
As the fan blade spins, vortices form at the end of the aerofoil. Our expertly designed tail wing mitigates this energy loss, stabilizes fan operation, and ensures the airflow aligns seamlessly with aerodynamic principles..
