Problems solved by technology

At present, the frame motor of the outer frame assembly of the control torque gyroscope mainly adopts the scheme of electromagnetic motor (permanent magnet synchronous motor or reducer with permanent magnet DC brushless motor). When the product does not output torque, the electromagnetic motor of the outer frame assembly still needs to consume about 12W of energy, that is, the control torque gyro group composed of 5 control torque gyroscopes needs to consume about 60W of energy without output torque, which cannot meet the power consumption requirements. There are strict requirements for the application of micro-satellites; at the same time, the frame motor must have enough torque to meet the driving force of the inner frame assembly when the control torque gyro outputs torque. If it is necessary to output a torque of 0.8Nm, a permanent magnet synchronous motor or a reducer with a permanent magnet DC without The weight of the brush motor solution is not less than 0.8Kg, which is relatively heavy compared to the control moment gyroscope products for micro satellites

Description

technical field [0001] The invention relates to a frame drive and power supply integrated assembly, which belongs to the field of space actuators. Background technique [0002] The control moment gyro belongs to the execution part of spacecraft attitude control, and is used for fast maneuvering and high-precision attitude control of spacecraft attitude. The control moment gyroscope generally consists of an inner frame assembly and an outer frame assembly. The inner frame component makes the control moment gyroscope have sufficient angular momentum elements, mainly including high-speed rotor, rotor motor and its supporting frame structure. The outer frame assembly is the element that enables the high-speed rotor and the rotor motor of the inner frame assembly of the control torque gyro to rotate and conduct electricity, and the inner frame assembly to rotate around the frame axis. It mainly includes the frame motor, angle measuring device, electrical transmission device and ...
