  • MULTI-DEGREE-OF-FREEDOM SPHERICAL MOTOR
    Publication number: 20220345014
    Abstract: A multi-degree-of-freedom spherical motor includes a primary frame, a secondary frame, a tertiary frame, a terminal rotor, a first rotating shaft, a second rotating shaft, a third rotating shaft, permanent magnets and electromagnetic coils. The electromagnetic coils are arranged on an inner surface of the primary frame. Two sides at a top portion of the primary frame are symmetrically connected to the secondary frame through the first rotating shaft. The tertiary frame is arranged inside the secondary frame in a non-mechanical contact manner. The terminal rotor and the tertiary frame are connected through the third rotating shaft. The permanent magnets are arranged on one side of the terminal rotor close to the primary frame. The secondary frame and the tertiary frame are connected through the second rotating shaft. The first rotating shaft, the second rotating shaft and the third rotating shaft are perpendicular to each other.
