The invention discloses an internal rotor magnetic suspension spherical surface gyro flywheel. The flywheel comprises a stationary part and a rotating part. The stationary part comprises an upper gyro chamber, a middle gyro chamber, a lower gyro chamber, a sealing ring, an axial spherical surface magnetic bearing stator, a protective bearing, a motor assembly stator, an axial displacement sensor assembly, a radial displacement sensor assembly, a radial spherical surface magnetic bearing stator and a Lorentz force magnetic bearing stator. The rotating part comprises a gyro outer rotating disk assembly, a gyro inner rotating shaft, sphere center adjusting backing rings and gyro rotor lock nuts. A spherical surface magnetic bearing is adopted to serve as supporting member, five-degree-of-freedom active suspension of the magnetic suspension gyro flywheel can be achieved, the interference of three times of translation control of a rotor in two times of radial twist control is eliminated, and then the moment precision of the high gyro moment instantly output by the gyro flywheel is increased.
