Single-piece three-axis magnetorquer

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.
