(Economic Information Broadcast by CCTV Finance)Micro special motor refers to a motor with small volume and output power, which has special performance and special purpose. They may seem small, but they have a huge impact. They can be used as ventilators to rescue critically ill patients and can also drive humanoid robot joints. Today's "Specialization, Refinement, Innovation, and Manufacturing Power" series reports walk into a company in Changzhou, Jiangsu, and take a look at the small "tricks" in electric motors?

The "voice coil motor" is a typical "micro special motor" that is not only small in size, but also one of the five core components of critically ill ventilators. The number of times the "voice coil motor" operates directly affects the service life of critically ill ventilators.

Liu Fei, R&D Director of Jiangsu Dingzhi Intelligent Control Technology Co., Ltd.:The international level has reached 30 million times, and our lifespan can reach twice that of them, which has greatly promoted the entire industry.

The secret to a longer lifespan is that this "voice coil motor" adopts a special sliding component, which successfully reduces the friction force and sliding wear of the "voice coil motor".

Liu Fei, R&D Director of Jiangsu Dingzhi Intelligent Control Technology Co., Ltd.:At present, the leading international level is that the friction force can reach up to 50 millinewtons, and we can already achieve up to 10 millinewtons.

This key technology was independently developed by a technical team led by Liu Fei. It took four months to overcome this "bottleneck" problem and completely break the monopoly of European and American countries in this field.

Liu Fei, R&D Director of Jiangsu Dingzhi Intelligent Control Technology Co., Ltd.:This product is currently sold at a relatively high price internationally, around $150 each (approximately RMB 1100). After mass production, we can sell it for approximately $70 each (approximately RMB 510).

With the successful development of the "voice coil motor", Dingzhi Intelligent has once again focused on the more high-end field of humanoid robots. Charge towards smaller and more technically challenging micro motors.

Lou Anyun, Deputy General Manager of Operations of Jiangsu Dingzhi Intelligent Control Technology Co., Ltd.:We can provide approximately thirty types of motors for application to humanoid robots.

Starting from scratch, Dingzhi Intelligent has originated from Germany and rapidly developed into Japan, gradually breaking through the problem of being stuck in the neck by foreign countries, and has begun to compete with industry giants on the same stage.

This issue is specialized and innovative, with unique skills:Between square inches, showcasing Chinese craftsmanship; A tiny difference showcases the spirit of craftsmanship. Striving for excellence in every process and meticulously crafted every product, domestic motors shine on the world stage.
