Patent ID: 8080911

Claim:
A spherical motor rotating in multi degrees of freedom, comprising: a hollow spherical-shaped stator installed with at least one 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, wherein the bobbin includes a first bobbin segment and a second bobbin segment formed with an inner layer winding member and an outer layer winding segment, respectively, wherein the outer layer winding member of the first bobbin segment is longer than the inner layer winding member, the inner layer winding member of the second bobbin segment is formed longer than the outer layer winding member, and the first bobbin segment and the second bobbin segment are allowed to be piled up one on another.
