According to the latest report of BI Intelligence, an authoritative research institution in the United States, the annual growth rate of consumer UAV market from 2015 to 2020 is 19%. Domestic UAV is also a thriving scene. DJI innovation announced that its total revenue in 2014 was close to 3 billion yuan, and the total revenue in five years increased by 100 times; the six-month valuation of Ehang increased by 25 times. This prospect has also attracted more industry participation. It is reported that MIUI will also enter the market. Rapoo technology invests RMB 50 million in ZERO TECH to enter the consumer UAV market, trying to change the competition pattern of the industry through strong alliance.

This announcement has caused many people in the industry to worry about whether export control will hit the UAV industry? How long will the popularity of the UAV market last? Of course, there are optimistic insiders who say that from a technical point of view, the introduction of the restrictions marks that China's UAV technology level has risen to the forefront of the world. The restrictions on exports may be technical protection measures, China's UAV technology is indeed the number one in the world, so it is necessary to restrict exports. Even some analysts think that the United States used to ban the export of high-tech products to China. Now it's our turn to restrict the export of high-tech products. This is a sign of China's strong science and technology. It can be predicted that China's export restrictions will gradually expand in the future.

But is it worth pondering that China's UAV motor technology is really ahead of the world?

The consumer UAV market is not endless.

At present, the most popular market is consumer UAV. The so-called "consumer UAV" refers to the civil UAV that is suitable for the operation of ordinary consumers, simple to start, and mainly used for flight and entertainment. At present, the market of consumer UAVs is mixed. In addition to the fuzzy regulatory standards, the state has not yet formed an authoritative technical quality standard, which to some extent lowers the competition threshold of domestic civil UAVs. Now the whole market of consumer UAV is expanding rapidly and showing the trend of explosive growth. As the power source of UAV, the micro motor industry is also widely concerned about this. Most people think that the market of consumer UAV will continue to rise.

However, during the interview, the micro motor world network found that the motor companies have different opinions on this. Fan Jianjian, senior manager of the technology center of XIZi Forvorda Electric Co., Ltd., holds a reservation on the market prospect of consumer UAVs. Fan Jianjian said: "although the market of UAV is rising rapidly, it is not needed by every family like cars. I don't think there are too many problems in the motor technology scheme of domestic consumer UAV, and this is not particularly difficult to achieve. Because consumer UAV is not a necessity, no one can guarantee its development prospect. Now, the more popular the market of consumer UAV is, the more calm the motor industry needs. "

Compared with consumer UAVs, UAVs applied in the industry are more professional and demanding. UAVs applied in the industry market are called professional UAVs. Some time ago, for example, Facebook launched a UAV with a wingspan of Boeing 737, which plans to provide Internet access services to the most remote areas of the world. Since then, the voice of UAV from the consumer market to the professional market (professional level includes industrial level and military level and other higher-end UAVs) has been heard constantly. Whether to research and develop products with high safety and maneuverability as soon as possible has become the key direction of UAV industry research and development.

The future development direction of UAV.

At present, the domestic motor industry can only meet the market demand of consumer UAV, so the professional UAV market will become the direction of the domestic UAV motor industry. Before that, Zhang Ke, director of the project of Shenzhen RAINBOW EAGLE UAV Research Institute, said clearly in an interview with micro electric world network: "in fact, the UAV market is also differentiated. If the market prospect of consumer UAV is to be observed, then the market of professional UAV is ready to be developed." Due to the high requirements of professional UAV for the relevant motor and motor control, the relevant manufacturers will be required to provide more accurate and stable motor and control scheme.

Zhu Haijun, director of the Development Department of China ZKDERUN R & D center, also agrees with the view of developing professional UAVs. He believes that although domestic consumer UAVs have reached the world's leading level, professional UAVs have not yet achieved higher achievements. Zhu Haijun said: "because the motor of consumer UAV is at a low power level, from the perspective of motor of the same volume and weight level, the requirements of domestic technology are relatively low. If we want to improve, we need to improve the whole line, including the whole material and design.". At present, in the field of consumer UAV, domestic motor and motor control are doing well, but from the perspective of higher-end market, domestic UAV motor system is still relatively backward in general. "

At present, many motor manufacturers have launched relevant motor schemes for professional UAVs, so there is no need to worry about the future development of professional UAVs. As a micro motor enterprise that has been transferred into the field of UAV, it is necessary to see that the application of professional UAV in power, security, agriculture, forest fire prevention, police and other sub sectors is growing steadily. In the uncertain future of UAV market, relevant motor manufacturers should improve product quality to meet the requirements of professional UAV. So, how can motors meet the requirements of professional UAV?

The motor control meets the demanding requirements of industrial level.

Compared with consumer UAVs, professional UAVs have higher requirements in safety, stability, modularization, portability and service support. The industry also distinguishes professional UAVs from consumer UAVs. The key to judge whether a UAV is professional or consumer is whether it has intelligent flight control system and special functions. In other words, the professional UAV can not only achieve autonomous flight, but also has stronger load capacity, outstanding endurance, large flight radius and remote control radius, which can realize the functions of automatic positioning and tracking, infrared thermal imager and topographic exploration and mapping.

Although the DC brushless motor used in consumer UAV has certain requirements in motor structure design, motor control algorithm and other technical aspects, it also needs strict performance test and technical verification system to ensure the reliability of the product, but as long as a high-performance FPGA chip can realize the function of Dual CPU in UAV, which can not only meet the information fusion of navigation sensors And it can realize the optimal control of UAV, so there is not too much technical difficulty.

According to the market and application manager of micro electro mechanical products in Asia Pacific region of ADI, the stability performance index of motor and controller is particularly important for the application of professional UAV, because the motor in UAV will generally bring strong vibration, once the shock absorption control is not good, it will generate great acceleration in the flight process, which will inevitably bring the change of gyro output, and then cause angle When the degree changes, the motor will delay action, and the user's intuitive feeling is that the UAV is not stable.

The increase of acceleration and weight will bring more pressure to the whole motor system. The reason why the UAV can hover is that the MEMS sensor can detect the change of pitch angle and roll angle of the UAV during the flight. When the motor control system detects the angle change, it can control the motor to rotate in the opposite direction, and then achieve the stable effect. The professional UAV needs at least four to six brushless motors to drive the UAV's rotor, and the motor-driven controller is used to control the UAV's speed and direction. Motor control system is very important to the stability of UAV. Therefore, the motor system of professional UAV should be more accurate and reliable, which is also the direction that the motor enterprises in the field of UAV motor need to improve.

The more people say that China's UAV is the number one in the world, the more relevant electric machinery industry should objectively analyze the future development trend of UAV. Only after occupying the market of professional UAV electric machinery can China's UAV electric machinery and even China's UAV be called the real strong one.
