Linear motors make the Chinese drones stunning the world. In Iraq, the real missiles hit 95%. Especially the series of high-end UAVs such as "Pterosaur", "Yun Ying" and "Fengyun" have once again sounded "made in China" Inspired, and these breakthrough products, linear motors have an indispensable role, today with the Mau motor for you to analyze linear motor UAV irreplaceable advantages.
Linear motor is a new type of servo motor, which has the characteristics of unlimited stroke length, long precision holding time, fast dynamic response and large starting thrust. The structure type adopted in the linear motor is a centrifugal-free structure, and it does not Will affect the speed of linear movement, at the same time have a relatively large acceleration, the maximum speed can be achieved at the moment of take-off. Because of these advantages, linear motor technology has been widely used in the field of drone.
Advantages of a linear motor in a UAV for high-speed linear motion:
1. Linear motor can produce strong electromagnetic thrust, it can not only reduce the cost and more secure, because the gunpowder is relatively safe, and has a strong concealment and the impact on the environment and other small features;
2. Linear motor drive used for the electromagnetic thrust-driven, without the need for intermediate conversion mechanism for the entire system of devices a significant significant simplification, on the one hand so that the transfer efficiency has been improved, on the other hand also achieved for the mechanical loss control;
3. The closed-loop control system of the linear motor system can more precisely regulate the output current so that the ejection energy can be more precisely controlled;
4. Linear motor can achieve high-speed straight-line UAV motion, linear motor with UAV launcher, the device can be 277km / h speed of 25 tons of heavy aircraft fired out;
5. The linear motor used in the energy mainly consists of linear AC motor and DC motor two, compared to the two, the DC motor is more suitable for the use of linear motor in the drone, because the DC motor is relatively simple, the thrust mass ratio Large, the quality also has a relatively good servo performance, to be able to achieve relatively large mobile speed within a relatively short distance.
