A claw-pole magnetic levitation torque motor includes a stator component and a rotor component. The stator component includes an end cover, upper and lower claw poles, coil skeletons, coils, and a flux guide sleeve. The cavity formed between the upper and lower claw poles accommodates the coil skeletons, on which coils are wound. The rotor component includes a ring-shaped shell, a permanent magnet, a base, and a shaft. The shell is fitted outside the claw poles, the bottom of the shell includes a base having a base platform shoulder, in the center of which a blind hole is opened. The lower end of the shaft is fixedly arranged in the blind hole, and the upper end of the shaft passes through the flux guide sleeve. The stator component is assembled with the rotor component through a gap-fitting between the magnetic guide sleeve and the shaft of the rotor component.
