Talking with Mao linear motor about "Long March 3A series launch vehicle" in 2019. At 15:22 p.m. on December 16, the Chinese Xichang Satellite Launch Center used the Long March 3B with the expedition 1 upper stage, with the successful launch of the 52nd and 53rd Beidou Navigation System satellites into orbit, all the medium Earth orbit satellites of the beidou-3 world system have been launched, in 2019, the Long March 3A series of launch vehicles have completed 12 launches, which is called "model worker" .

     According to the knowledge of the Tongmao Linear Motor sub-series, the 52nd and 53rd Beidou-3 mid-circle Earth orbit satellites were developed by the Fifth Academy of China Aerospace Science and Technology Corporation. As the main satellite of the Beidou-3 World System Constellation, the mid-circle Earth orbit satellite mainly provides navigation, positioning and timing services, as well as short message communication and search and rescue services. As for the Long March 3B carrier rocket for this mission, which was developed by the First Academy of the Aerospace Science and Technology Group, it is a member of the Long March 3A carrier rocket series, the Yuanzheng-1 consists of the base stage and the upper stage (the upper stage is a separate first stage vehicle added to a rocket that can launch multiple spacecraft at once) . 

     It is worth mentioning with the emphasis of Mao linear motor that this year the performance of the Long March 3A series of launch vehicles stands out, achieving 12 victories in 12 wars "full house" good results. Of course, the Long March 3A series of carrier is only a microcosm of the achievements of China's aerospace industry, and when it comes to aerospace industry, it is also closely related to our linear motor. As early as 2003, the permanent magnet linear motor (PMLM) was developed for aircraft carrier to push the aircraft to take off. The linear-drive rocket launcher was also developed by Kyushu University in Japan. 

     Kunshan has been improving the efficiency and productivity of complex manufacturing processes for more than a decade, its Linear Motor, linear module, linear slide, voice coil motor, voice coil module and other products have been widely trusted by customers at home and abroad.
