Tongmao linear motor He Changzheng No. 11 "space shuttle" started. At 12:42 a.m. on April 26th, the Changzheng No. 11 solid carrier rocket developed by the first institute of the China Aerospace Science and Technology Corporation accurately delivered the five satellites of Zhuhai No. 1 to the scheduled orbit.

     Yang Yiqiang, the chief commander of the "Yang 11" rocket of the First Hospital, explained that in the field of commercial space, "Changyi" initiated three kinds of launch service models: "Space Shuttle", "Space Shuttle" and "Space Shuttle" to provide users with Constellation network one-stop solution.

     The “Space Shuttle” service of the Long March 11 is the largest number of satellites launched on the same orbital surface of China’s constellation network.

     Yang Yiqiang said that the four launches of the 11th Long March were all successful, and they all achieved zero problems in the flight process and an accuracy of 100 meters in orbit. As the rockets become more mature and reliable, launch services will also be more convenient and flexible, and they can effectively meet the launch requirements of China's commercial space small-satellite large-scale high-density networking.

     Tongmao linear motor has simple structure, high precision, high efficiency, high response, no maintenance, no cogging effect, and does not require reversing. Kunshan Tongmao's independent R&D and production of voice coil linear motor can reach a maximum positioning accuracy of 0.1mm. Suitable for short stroke, fast response, high precision closed loop servo control.

     Tongmao linear motor has theoretically infinite advantages such as infinite resolution, no hysteresis, high response, high acceleration, high speed, small volume, good force characteristics, and easy control, making it more suitable for high acceleration and high frequency excitation. , fast and high-precision positioning of the control system. Modern disk drives, optical disk drives, and some high-precision positioning system actuators are all driven by Tongmao linear motors.
