The invention provides a three-dimensional Braunbeck driving coil of a nuclear magnetic resonant gyroscope. The three-dimensional Braunbeck driving coil comprises a three-dimensional coil group, wherein the three-dimensional coil group comprises an x-axis Braunbeck coil, a y-axis Braunbeck coil and a z-axis Braunbeck coil, each one-dimensional coil comprises two pairs of four coils, the coils are coaxial, the four coils are arranged oppositely in a paired way, an enameled wire is wound around the four coils to make the four coils connected in series, a tap is reserved, the four coils which are coaxial are divided into a big group and a small group and are symmetric about a geometric center O, and the purpose of expanding a central uniform region is achieved by setting a position relation between the big group and the small group. By superposition of magnetic fields among the coils, an error remaining item of a central magnetic field is eliminated, so that the uniformity of the magnetic field is improved. A traditional Helmholtz coil is substituted by the Braunbeck coils, and the three-dimensional Braunbeck driving coil has the characteristics of small size and good uniformity of the central magnetic field, and has very important significance to miniaturization of the nuclear magnetic resonant gyroscope.
