Problems solved by technology

Among them, the first article mainly introduces the design and implementation of the magnetic bar magnetic torque device. The magnetic bar magnetic torque device has the advantage of generating a large magnetic moment, but the requirements for the magnetic core material are very high, and the cost is relatively high. And the magnetic rod type magnetic torque device has a large residual magnetism
The second article mainly introduces the design and realization of the air-core magnetic torque device. The parameter design is based on the principle of the minimum product of mass and power consumption. It cannot guarantee the maximum magnetic moment, and it needs to process and manufacture special winding slots, which increases the process. The complexity increases the quality of the designed magnetic torquer

Abstract

The invention relates to a high-energy-efficiency hollow magnetic torquer design method and manufacturing process. The basis physical principle than magnetic force acts on an electrified coil in a magnetic field, the magnetic torque of a hollow magnetic torquer is optimized under the constraint conditions of size, quality and power consumption of the hollow magnetic torquer, and the manufactured magnetic torquer is lightweight, low in energy consumption, small in residue magnetism and large in output magnetic torque. The requirements of the posture control system of a near-earth orbit modern small satellite for magnetic torquers can be satisfied. Efficient magnetic torquers under different constraint conditions can be manufactured by the method. Traditional magnetic torquers using magnetic bars are large in magnetic torque, but high in magnetic core material requirement and large in residual magnetism. The method uses a hollow coil, the defect of large residual magnetism is overcome. Due to the fact no magnetic cores are used, the mass of the magnetic torquer is reduced greatly.
