The invention discloses a six-degree-of-freedom full-active control Lorentz pod, which comprises a rotor system and a stator system, and is characterized in that the rotor system comprises a pod body, an axial translation and radial deflection magnetic bearing rotor, a spherical motor rotor assembly and a photoelectric encoder rotor grating; the stator system comprises an axial translation and radial deflection magnetic bearing stator assembly, a spherical motor stator assembly, a radial support, a photoelectric encoder reading head, a radial spherical magnetic bearing stator assembly, an axial support, an axial displacement sensor, a deflection displacement sensor and a radial displacement sensor. Through the six-degree-of-freedom full-active control Lorentz pod with a displacement detection point and a magnetic bearing translation control point being co-located, errors caused by a sensor and magnetic bearing conversion matrix are eliminated, and the imaging quality of a spacecraft camera is improved. In addition, the spherical rotating motor is adopted to control the orientation of the pod rotor, the 360-degree azimuth angle active adjustment capability can be achieved, and the earth observation maneuvering imaging quality of the camera is further improved.
