Description

technical field [0001] The invention relates to a high-speed linear electromagnetic propulsion and electromagnetic braking system, belonging to the technical field of motors. Background technique [0002] UAV electromagnetic ejection technology has technical characteristics such as low take-off speed, large take-off mass range, small launch kinetic energy, low launch frequency, small power supply, small acceleration, and low current. Compared with technology, it reduces the technical requirements for power supply, materials and switches. At the same time, its low-speed advantage and good inheritance all strongly support the practical application of UAV electromagnetic ejection. [0003] Figure 1-Figure 3 It is a UAV linear electromagnetic ejection system, in which figure 1 is the primary of the linear induction ejection motor, figure 2 is the secondary of the linear induction ejection motor, image 3 is the cross section of the linear induction ejection motor. The lin...
