Abstract
A spherical motor rotating in multi degrees of freedom has a reliable capability of determining positioning. The spherical motor includes a hollow spherical-shaped stator installed with a bi-level bobbin wound by coil generating a synthesized magneto-motive force on an inner surface thereof; and a rotor formed inside the stator and rotating around a shaft, wherein a slope of the shaft is adjusted by the synthesized magneto-motive force. Two or more of the bobbins are provided and installed at regular intervals along the inner surface of the stator, and the rotor includes one or more permanent magnets. The spherical motor rotating in multi degrees of freedom, formed with the above mentioned figures, can embody multi degrees of freedom by the interaction between the flowing current in the winding coil around the bobbin and the permanent magnet.
