As of August 1,2020, the Tokyo Olympic Games indoor swimming events were all over, China's swimming team won 3 gold, 2 silver and 1 bronze, of which China's swimmer Zhang Yufei won 2 gold and 2 silver. 

   Zhang Yufei Zhang Yufei of China broke the Olympic record by winning gold in 2:03.86 in the Olympic Games 200m butterfly final in Tokyo on the morning of July 29,80 minutes later, zhang Yufei won the women's 4,200-meter freestyle relay in 7 minutes, 40.33 seconds, breaking the Olympic record as well. 

   And did you know that the hard-won four swimming medals are backed up by space technology? According to Tongmao's linear motor, as early as December 2019, the General Administration of Sport of China Issued Project Requirements to the Ninth Academy of China Aerospace Science and Technology Group, hope to use advanced space technology, research and development of precision measurement products, to help swimmers strengthen the scientific training, improve competition results. And since the Ninth Academy of China Aerospace Science and Technology Group received the request from the General Administration of Sport of China, it has appointed 13 times photoelectric companies under the ninth academy to work on this kind of products. At present, the motion measurement products developed by times photoelectric company have taken shape smoothly, the single unit weighs only 16 grams and consists of four parts: inertial navigation subsystem, positioning and velocity measurement subsystem, video acquisition subsystem and data comprehensive analysis system, it can realize the functions of posture measurement, position and velocity measurement, motion video shooting, data integration and 3D model driving. When it comes to aerospace technology, a lot of linear motor is closely related, linear motor has been widely used in aerospace field. 

     The TONGMAO LINEAR motor is developed and produced by Tongmao Electronics Co. , Ltd. in Kunshan. One of the main application scenarios is in aerospace, tongmao linear motor by the Nanjing University of Aeronautics and Astronautics, Beijing University of Aeronautics and Astronautics, Shanghai Beidou and other universities and enterprises.
