Embodiment Construction

[0023] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The magnetic torquer is composed of two parts, the energizing circuit and the corresponding control circuit. The energizing circuit can be a magnetic rod with a magnetic core or an air-core coil. The monolithic magnetic torque device involved in the present invention includes energization circuits in three orthogonal directions of x, y and z and corresponding drive control circuits, and the energization circuits in the two orthogonal directions are all under the action of driving current The magnetic bar that generates the magnetic moment, and the energized circuit in the other orthogonal direction is the air-core coil that generates the magnetic moment under the action of the driving current. The air-core coil and two magnetic bars are integrated on the coil circuit board, and the three drive circuits are integrated on the drive On the circu...

Abstract

The invention discloses a single-piece three-axis magnetorquer, and belongs to the technical field of satellite attitude control. The single-piece three-axis magnetorquer comprises three electrification loops in the orthogonal direction and corresponding driving control circuits, wherein the two electrification loops in the orthogonal direction are respectively magnetic bars generating the magnetic moment under the effect of driving current, the third electrification loop in the orthogonal direction is a hollow coil generating the magnetic moment under the effect of driving current, the hollow coil and the two magnetic rods are integrated on a coil circuit board, three driving circuits are integrated on a driving circuit board, the driving circuit board is connected with a coil circuit board through a standard row pin, the two magnetic bars are vertically integrated on the circuit board for forming a Descarte rectangular coordinate system, n layers of hollow coils are wound on the coil circuit board, and a hollow coil array with the wire diameter being d is formed. The single-piece three-axis magnetorquer has the advantages that the coil circuit and the driving control circuit are integrated on the circuit board, in addition, two circuit boards are conducted through a pointer, the magnetorquer is realized by the single-piece structure, and the structure is simplified.

Description

technical field [0001] The invention discloses a monolithic three-axis magnetic torque device, which belongs to the technical field of satellite attitude control. Background technique [0002] At present, there are mainly three types of on-board magnetic torquers developed at home and abroad: switch type magnetic torquer, unipolar linear adjustable magnetic torquer and bipolar linear adjustable magnetic torquer. The executive components of the magnetic torquer are mainly magnetic rods and air-core coils. A design scheme for the drive circuit of a large magnetic moment magnetic torque device (Fan Jiakun, Wang Youping, Cui Weiman, Space Control Technology and Application, 2010, 36(2):58-62.) proposed a 1500~2000A· The driving circuit design scheme of m2's large magnetic moment switch type magnetic torque device, the circuit mainly adopts the form of pulse width modulation and H bridge drive, and the output excitation current changes linearly according to the different input s...
