500V UAV motor realized the first domestic supplier of Xinjiang, Jingshan light machine panic?

[500V UAV motor realizes the first domestic supplier in Xinjiang, is the Jingshan light machine panic?] The drone is a hot industry and topic that can compete with new energy vehicles in the military, security, logistics, medical, and agricultural fields. It has been widely used, but at present, there are fewer than ten companies that have mastered the motor technology of one of the core technologies of drones. "Exclusive beast" is a big one in Dajiang, and Jingshan Light Machine has eliminated 100 electric motor enterprises to become a supplier in Dajiang. However, a "black horse" appeared recently, and its motor technology was firstly patented and patented in China. In the future, will there be any new changes in the UAV motor market?

New changes in the drone market in 2018

On May 16, Liu Qiangdong, chairman of the board of directors of Jingdong Group, said that Jingdong is preparing to build more than 100 drone airports in Sichuan and Shaanxi, and plans to deliver high-quality agricultural products from remote villages to all large and medium-sized cities in China within 24 hours. And reduce the logistics costs in the province by 70%.

On May 29th, hungry, it was announced that it was allowed to open the first batch of UAVs in China. The delivery drones were officially put into commercial operation, which means that drones will become a key breakthrough for intelligent logistics.

On May 31, the Changying Xinyi drone took the "wings" of the rookie. The two sides joined forces with FAW Jiefang and Sagitar Juchuang to create an unmanned logistics plan called "Hump". Among them, Changying Trust, as an ecological partner in the field of rookie drones, will strive to build the first drone designed for logistics scenes in China.

On June 4th, photos of China's new drone "dark sword" were revealed on the US website. The US media said that this drone will become a nightmare for the United States. China is likely to replace the United States in the future and become the world's number one air force power.

On June 5th, the UAV leader and the "unicorn" enterprise DJI cooperated with the security company Axon to sell the drone with video function directly to the police through the Axon aviation program. This cooperation means no sale. The new channels for man-machines are fully open.

In addition, at the Microsoft Build Developer Conference, Microsoft and drone maker DJI also announced a new partnership aimed at bringing more Microsoft's machine learning intelligence to commercial drones. The board of directors of DJI expects that by 2022, the revenue of Dajiang will reach 170 billion yuan.

The new motor won the first in China

The air outlet of the drone has been opened in 2014, and with the influx of capital, the drone has been officially opened. Relevant data shows that there are nearly 200 UAV manufacturers in China, but there are fewer than 10 companies that master the core technology of UAV manufacturing.

Chip technology, power supply technology, flight control technology, environmental adaptability and communication and navigation system are the core of the development of the drone industry, which is widely recognized by the industry. However, most of the core technologies have been imported and foreign-funded enterprises.

Take UAV flight control technology as an example, there are not many companies with solutions. At present, only the WooKong series of Dajiang and the Naza series flight control system, the dual-safety flight control system with zero intelligence control, and the SUPERX and MINIX flight control systems of the company are recognized as the more advanced flight control systems in China.

In addition, as drones are widely used in industrial or commercial scenarios, the dynamic response performance and reliability requirements of power systems are also constantly increasing, so the drone motor technology has attracted the attention of the industry.

On May 10, there was a problem with the power control system, and a drone wounding incident occurred in Beijing. According to the monitoring screen, when the boy is playing, a four-axis drone descends from the sky, and a pair of centimeters of wounds (9 stitches on the face) are pulled out on the boy's face, and the drone is controlled. 14-year-old German boy. Because the perpetrators were underage and were not bound by Chinese law, the perpetrators and their guardians left the police station that night.

This is not simply a simple accident, but the security of the drone is reflected in the back. In recent years, accidents caused by drones have been repeated one after another. At present, the national level is constantly improving the real-name certification of drones. However, the key issue is to strengthen the safety performance testing and core technology research and development of drones.

Recently, Shuangjie Technology's independent intellectual property rights of 500V high-voltage motor technology won the first in China, and obtained the motor patent of high-power new energy UAV power system.

The data shows that this motor is a high-voltage brushless drone power system, DC power supply 500V, single motor can generate 50KG tensile force when rated current 13A; single motor pull force can reach 80-100kg when peak current is 30A. The system eliminates the step-down module on the drone, and uses the ultra-fine high-voltage cable to directly supply the high-voltage motor on the aircraft. It adopts the high-voltage (DC100V-DC500V or above) low-current (rated less than 15A) power supply design to improve Efficiency of each power system. This not only greatly reduces the operating temperature of the motor, but also improves the efficiency of the motor.

In addition, for the high-altitude large tethered flight system, by greatly reducing the current of the H7 high-voltage motor, while providing a large pulling force, the tie line becomes lighter and thinner, and the invalid load of the flight platform is reduced. In addition, because the high-voltage cable is directly powered by the H7 high-voltage motor, it is no longer necessary to mount heavy and expensive buck modules and cooling systems in the tethered flight system, which not only greatly reduces the weight of the fuselage, but also greatly reduces the weight. manufacturing cost.

According to industry insiders, this motor effectively reduces the weight of the transmission line and the weight of the aircraft body, and will become the mainstream of the power system of the industrial drone industry, which is revolutionary in technology. In practical applications, it has also been well received by various research institutes.
