Embodiment Construction

[0030] A magnetic torque device for micro-satellites, such as Figure 1-3 As shown, it includes a left mounting frame 3, a coil 5, a magnetic core 6, a right mounting frame 8, a left insulating barrier (not marked in the figure) and a right insulating barrier 9. This magnetic torquer can be directly applied to a 50Kg class microsatellite , the magnetic core 6 is respectively threaded with the left mounting frame 3 and the right mounting frame 8 using titanium nails 2, and the assembly is sealed with D04 glue. The magnetic core 6 adopts permalloy national standard 1J85, and its diameter is The length is 220mm. This material has outstanding advantages such as small size, light weight, fast response, high magnetic moment output accuracy, and high reliability. It meets the lightweight design, reduces the residual magnetism to an extremely small range, and has high output accuracy. Coil 5 adopts a single-layer polyimide enameled wire to be wound on the surface of the magnetic cor...

Abstract

The invention provides a magnetic torquer for a microsatellite and an assembly method thereof, and belongs to the field of lightweight design technologies and assembly processes of the magnetic torquer. The magnetic torquer comprises a left mounting rack, a coil, a magnetic core, a right mounting rack, a left insulating baffle plate and a right insulating baffle plate; the two ends of the magnetic core are connected with the left installation frame and the right installation frame respectively, the coil is wound on the magnetic core, a left insulation blocking piece is arranged at the connecting position of the magnetic core and the left installation frame, and a right insulation blocking piece is arranged at the connecting position of the magnetic core and the right installation frame; the magnetic core is made of permalloy meeting the national standard 1J85, and the coil is wound by a single-layer polyimide enameled wire in a multi-layer and multi-turn mode. The magnetic torquer is designed in a light weight mode, a magnetic core material with low quality and low residual magnetism in national standard products and a single-layer enameled wire with the optimal scheme wire diameter are selected, an optimal winding scheme is adopted through a multi-target recognition method, the design structure is reduced, the weight of the magnetic torquer is reduced to the maximum extent, the optimal design is achieved, and therefore the satellite launching cost is reduced.

Description

technical field [0001] The invention belongs to the field of lightweight design technology and assembly technology of a magnetic torque device, and in particular relates to a magnetic torque device for a tiny satellite and an assembly method thereof. Background technique [0002] In the prior art, the patent No. CN 105743232A is disclosed, and the name is "Miniature Magnetic Torque Device and Its Manufacturing Method for Amorphous Rod". Defensive question. Since this technology has no protective facilities and installation facilities, the installation surface of the magnetic torque device is extremely vulnerable to damage, or it can be installed through wool felt, etc., which will also make the redundant objects on the tiny satellites uncontrollable. Contents of the invention [0003] The purpose of the present invention is to solve the problems of high weight, poor practicability and weak protection ability of the existing magnetic torque device, and provide a magnetic t...
