1: How long does your company built up ?
ASTA was built in 2013, and our team is about 15 colleagues at present. Our flight base and product line are near from our company. It only takes half an hour to get there. And moreover, we can product 30-50pcs monthly.
2. Q, Does your company participate to Canton Fair?
Sure, we joined in before. And we are looking forward to more professional foreign exhibitions of agriculture uav.
3: Q:which brand does your ESC belong to? ( Electronic Speed Controller )
We choose Sine wave (FOC) ESC. which is driven by sine wave, and can blackout and recover energy automatically. and also has a better throttle linear when the motor decelerates. Coz (FOC) ESC is driven by current, it is more advanced and advantageous than traditional BLDC square wave ESC ,which is driven by voltage. Below are all the advantages of FOC ESC in agriculture uav.
No 1, little sound, no howling noise.
No 2, low temperature. The temperature can be reduced by 10°compared to the BLDC which cannot be..
No 3, high efficiency. the efficiency of uav can be improved to 8%-10%.
No 4, faster response. The drone can keep stable and response quickly when flying.
4 Q How about your motor ?
The special and f irm design of motor make the stator interlocked for triple dead cycle. We called the snap ring. Anti-loose snap ring and screw are triple interlocked, it is anti-fatigue, impact-resistant, maintenance-free, ensure that motor still be very reliable in High-power and high-speed operation. layered design, conductive copper piece fits seamlessly into the heatsink parts to make internal heat can be expelled out more quickly. the radiator is designed like wave slotted vane. increases the heat dissipation area; the special design of rotor allows for cooled done independently during operation. These optimized designs effectively reduce the interference of temperature to the flight, extend the working hours, and more stable and smoothly.
5 Q: What is propeller you use ?
A: The propeller is made of Ultra Carbon Pro, a lightweight and strong special carbon fiber composite material. The new technology enhances the weather resistance of the blade and combines the advantages of low inertia, high strength and high rigidity. The aerodynamic design of the propeller is coordinated with the electromechanical design of the motor, resulting in higher power efficiency and longer battery life.
6 Q:What is software for your drone ? and remote controller
A: We use the DJi N3 or A3 Link. it control the aircraft directly through the powerful intelligent mobile Dji MG App to plan a spray field . also you can choose from two operation mode. automatic mode or manual mode. Which make the flight easily and efficiently. Improve task execution efficiency . and it is more stable
7. High pressure and centrifuge nozzle
The advantage of pressure nozzle:
Great pressure and strong penetrating power of this kind of nozzle makes the liquid is sprayed out instead of dropped out. Also less evaporation in dry area.
The advantages of centrifugal nozzle:
The principle is that the liquid can be driven away by the high-speed rotation. Uniform liquid atomization, little difference in droplet diameter.
8 How about charge and charge time ?
Our charge station has 2 or 4 ports. So you can charge 2 or 4 pcs batteries at one time. And it's suitable for power between AC100V-240V. you'd better use a portable charger when it's out of power.
