The important application of linear motor in electromagnetic ejection. On May 28 this year, Trump suddenly announced that he would no longer prefer a new type of electromagnetic ejection system on aircraft carriers, but instead reuse traditional steam power catapults. In stark contrast, in the eyes of Academician Maweiming, the father of Chinese ejection, the electromagnetic ejection system must be superior to the steam catapult, and its function has almost doubled.
In this period, the small series of linear Motors shared with everyone the basic knowledge of electromagnetic ejection. It is reported that electromagnetic ejection refers to the fact that the launched object does not use its own power device, and electromagnetic force is used as an acceleration method. A launch method that achieves emission by obtaining enough motion energy by the power given by the launcher.
According to the linear motor, the electromagnetic ejection system Pk steam catapult, easily won. The ejection equipment of a traditional aircraft carrier is the above-mentioned steam catapult. It consists of a launch system, a steam system, a cable tensioning system, a lubrication and control system, etc.. It has low efficiency, many supporting facilities, cumbersome systems, and high maintenance costs. Defects such as higher material requirements. The projectile launched by electromagnetic ejection not only has a fast speed, uniform acceleration, and a long range, but also relies on advanced power electronic devices. The electromagnetic launch process can be fully controlled.
The point is that the ejection motor is a core component in the entire electromagnetic ejection system. It is an execution component that converts the input energy into kinetic energy, thereby accelerating the projectile to a specified ejection speed within a fixed distance. At present, the motor used in electromagnetic ejection system is mainly linear induction motor and linear permanent magnet motor, so the performance of linear motor has a direct impact on the entire electromagnetic ejection system.
In the research and development of the electromagnetic ejection system, Ningbo Materials has achieved great achievements, and Ningbo Materials Co., Ltd. has purchased several high-performance linear motors from Tongmao as a cooperative customer of Kunshan Tongmao Electronics Co., Ltd..
Kunshan Tongmao Electronics Co., Ltd. has been established for more than ten years. In order to enhance the market competitiveness of Tongmao and the quality of direct drive products, Tongmao also established branches in Suzhou and Taizhou, and sales service centers in Taiwan, Beijing and Chengdu. At present, the company's linear motor and other products have been recognized by many large customers at home and abroad, and 70 % of the products are sold to Europe and the United States and other places.
