On August 1, Zhiju Technology welcomed representatives from the Civil Aviation Administration and eVTOL (Electric Vertical Takeoff and Landing Aircraft) customers to inspect and guide the production site at the company's Liuzhou base, witnessing together the assembly and testing of the first batch of aviation-grade electric drive assemblies independently developed by the company. The successful rollout of the product marks an important milestone in the company's development, signifying a solid step forward in the low-altitude economy sector.。

Background of Low-altitude Economic Development

The low-altitude economy is an important focal point for developing new qualitative productive forces. As a new economic form, the low-altitude economy features the core characteristics of high-tech leadership, efficient operation, and high-quality development. Its related products mainly include drones, eVTOLs, helicopters, and traditional fixed-wing aircraft. Among the many products in the low-altitude economy, eVTOL (Electric Vertical Take-off and Landing) shares some commonalities with new energy vehicles. The low-altitude economy is a key development strategy direction for the company. Leveraging its strong positive R&D capabilities, the company has quickly launched this internationally leading aviation-grade electric drive assembly product, with a power density exceeding that of industry competitors by 30%-50%, comparable to top international eVTOL companies like JOBY and ARCHER. While maintaining lightweight design, it can provide higher thrust. Additionally, the maximum efficiency of this electric drive is 10% higher than the industry average, significantly enhancing energy utilization and reducing operating costs. The company has independently developed and established over 20 testing platforms, including motor performance testing, durability testing, and system integration testing, to comprehensively verify its technological solutions.。

Technical difficulties and innovative breakthroughs

In discussions with visiting experts, Zhiqu Technology conducted an in-depth analysis of the challenges and innovative designs in aerospace electric drives.:

1.The ultra-high power density drive technology of aviation electric drive assemblies can provide the same power as a 120 kW vehicle electric drive, but at only one-third of the weight, primarily due to the application of innovative motor cooling solutions, insulation solutions, multifunctional oil pipes, and more than ten other innovative materials and technologies.。

2.Advanced thermal management technology for aviation electric drives must operate stably in extreme environments, with higher cooling system requirements than those for automobiles. Zhidrive Technology has adopted industry-leading liquid cooling and air cooling hybrid cooling technology, ensuring reliable system operation in the range of -40°C to 80°C and at altitudes of 7,000 meters.。

3.High-precision control technology for aviation electric drive involves complex control and requires support for multi-axis control and high-precision operation: ZhiDrive Technology's intelligent control system achieves real-time monitoring and adjustment accuracy of 0.1%, and is equipped with dual communication channels and self-locking propeller functions, enhancing the system's dynamic response capability and stability.。

4. High standards of durability and reliability. The motors developed by Zhichu Technology have undergone more than 5,000 hours of rigorous testing, demonstrating an extremely low failure rate that far exceeds industry standards. At the same time, Zhichu Technology's electric drive uses a modular architecture, making maintenance and upgrades easy, further reducing operational costs and the expenses related to changes in airworthiness.。

Future Cooperation Prospects

Zhiqu Technology has completed the integrated design and mass production of over 10 electric drive systems for automotive and aviation, including a one-stop self-research capability covering motors, control systems, reducers, and thermal management systems. During this visit, representatives from the Civil Aviation Administration and eVTOL clients fully recognized Zhiqu Technology's technical strength and innovation capabilities. They also toured the production process of the company's new energy vehicle electric drive assembly and hybrid powertrain, highly praising the company's highly automated and flexible production lines and comprehensive product quality assurance system, expressing confidence in future deep cooperation.。
