Electromagnet-permanent magnet hybrid boosting structure with multiple magnet rings outside electromagnet

Abstract

The invention discloses an electromagnet-permanent magnet hybrid boosting structure with multiple magnet rings outside an electromagnet. The main structure of the electromagnet-permanent magnet hybrid boosting structure comprises four parts, namely an electromagnet core 1, an electromagnet winding 2, the multiple axial magnetization magnet rings 3 and a magnet ring fixing external sleeve 4, wherein the electromagnet winding 2 is wound at the outer side of the electromagnet core 1; the multiple axial magnetization magnet rings 3 are arranged on the electromagnet winding 2 in a sleeving way and are fixedly arranged at the inner side of the magnet ring fixing external sleeve 4 together; the magnet ring fixing external sleeve 4 and the electromagnet core 1 are kept in a parallel movement state.

Description

Technical field [0001] The invention relates to an electromagnetic permanent magnet hybrid boosting structure with multiple magnetic rings on the outside of the electromagnet, especially a plurality of magnetic rings are sleeved on the inner side of the moving shell, the electromagnet winding and the iron core are on the inner side, and the multi-ring combination is sleeved on the electromagnet iron. The drone ejection device outside the core. It belongs to the technical field of unmanned aerial vehicle catapults. Background technique [0002] There is no electromagnetic catapult that has been successfully tested in China, so the military is in urgent need of this product. However, many laboratories in China have not successfully tested electromagnetic catapults. The reason is that the energy conversion between electromagnets and permanent magnets is not clear. Its design often uses only one permanent magnet corresponding to one electromagnet, so the electromagnet energy re...

[0002] There is no electromagnetic catapult that has been successfully tested in China, so the military is in urgent need of this product. However, many laboratories in China have not successfully tested electromagnetic catapults. The reason is that the energy conversion between the electromagnet and the permanent magnet is not clear.

Its design often only uses one permanent magnet corresponding to one electromagnet, so the electromagnet energy received by the moving permanent magnet is not enough to drive the drone to fly at high speed
