Abstract

The invention discloses a method for compensating nonorthogonality of a three-axis magnetic field coil through a winding. In the method, coil windings KXY and KXZ are also wound on an X-axis magnetic field coil frame besides the coil windings KX1, KX2 and KXn which meet other functions for compensating the nonorthogonality between the X axis and the Z axis and the nonorthogonality between the Z axis and the Y axis; and the coil winding KYZ is also wound on a Y-axis magnetic field coil frame besides the coil windings KY1, KY2 and KYn which meet other functions for compensating the nonorthogonality between the Y axis and the Z axis. In the method, two groups of nonorthogonality compensating coil windings are wound on the coil frame in each direction of the three-axis magnetic field coil; and through the two groups of nonorthogonality compensating coil windings, magnetic field nonorthogonality caused by the nonorthogonality of a three-axis coil magnetic axis of the three-axis magnetic field coil can be compensated. By the method, the nonorthogonality of the three-axis magnetic field coil can be reduced to the level of between 0.5'' and 5'' from the level of between 0.1 degree and 0.3degree adjusted in a pure mechanical mode.

Description

technical field [0001] The invention relates to a method for compensating the non-orthogonality of a three-axis magnetic field coil, in particular to a method for compensating the non-orthogonality of a three-axis magnetic field coil through windings. Background technique [0002] Traditional three-axis magnetic field coils are composed of coils perpendicular to each other in the X-axis, Y-axis, and Z-axis directions. The orthogonality between the magnetic axes of the three coils mainly depends on mechanical means to adjust the verticality between the three coil frames. degree method is guaranteed. This method can ensure that the non-orthogonality of the three magnetic axes of the three-axis magnetic field coil is about 0.1°-0.3°. Due to the limitation of the mechanical properties of the bobbin, it is difficult to further reduce the non-orthogonality among the three magnetic axes. When the three-axis magnetic field coil is used to calibrate the orthogonality of the three-a...
