Problems solved by technology

The development cycle of traditional flywheels is generally several months or even one year, while the overall development cycle of low-cost micro-nano satellites is only one year and the development cost of the whole satellite is low, so traditional flywheels cannot meet the mission requirements

Abstract

The invention discloses a flywheel mechanism for a micro / nano-satellite, relates to a flywheel mechanism and aims at solving the problem that the micro / nano-satellite in the prior art is not provided with a flywheel which is short in manufacturing period, simple in structure, low in cost and reliable in performance. The flywheel mechanism comprises a motor support, a damping cushion, a brushless motor, a wheel body and a protective cover, wherein the damping cushion is a rectangular frame body; a through hole for mounting the motor is formed in the rectangular frame body; the damping cushion is arranged on the motor support; the brushless motor is arranged on the motor support; the damping cushion is arranged between the brushless motor and the motor support; the output end of a rotating shaft of the brushless motor is sleeved by the wheel body; and the protective cover is arranged on the motor support and is buckled outside the wheel body. The flywheel mechanism is used for the fields of flight and spaceflight.

Description

technical field [0001] The invention relates to a flywheel mechanism, in particular to a flywheel mechanism for micro-nano satellites. Background technique [0002] The reaction moment flywheel is the main actuator of the satellite attitude control system. The flywheels of traditional satellites are produced and developed by professional aerospace agencies, which have the advantages of high reliability and stable performance, but the disadvantages of high cost and long development cycle. And it takes up a lot of satellite space, and the development cost is basically in the millions. At present, most of the flywheels used in spaceflight are developed by aerospace institutes, and their mass is relatively large, while the mass of ordinary nano-satellites is less than 20kg. The 100 kg satellite with practical functions plays an important role in the fields of scientific research, national defense and commercial use. The development cycle of traditional flywheels is generally s...
