Magnetic compensation coil structural component for miniature nuclear magnetic resonance gyroscope

The invention provides a magnetic compensation coil structural component for a miniature nuclear magnetic resonance gyroscope, wherein a mandrel bracket is in a cylindrical shape, with an atomic gas chamber optical path component being arranged inside, and a wire winding groove as well as a paster groove being arranged on the outer wall thereof for fixing a transverse magnetic compensation coil and a vertical magnetic compensation coil. The vertical magnetic compensation coil is a circular Helmholtz coil structure enwound by a varnished wire; besides compensating a vertical residual magnetic field of the gyroscope, the vertical magnetic compensation coil is also used for providing a uniform static magnetic field for the gyroscope. The transverse magnetic compensation coil employs a saddle-type coil structure; the transverse magnetic compensation coil is used for compensation a transverse residual magnetic field of the gyroscope. The power is supplied to each coil independently; the coils are all printed on one flexible circuit board, sticking inside a mounting groove of the internal mandrel bracket in a bended manner. Comparing with the prior art, the magnetic compensation coil structural component is better in magnetic field evenness, more compact in structure, better in technology, easier to be installed, integrated and maintained.
