PURPOSE:To control three degrees of freedom by one motor by combining magnetic fields of three directions which cross perpendicular to each other, thereby taking a rotational shaft of a magnetic field in any direction of the three directions. CONSTITUTION:Windings 2x, 2y, 2z which generate revolving magnetic fields are provided around x-axis, y-axis and z-axis which cross perpendicularly to each other are provided in a stator 1 which forms a spherical hollow shell. These windings 2x, 2y, 2z are respectively connected through controllers for controlling the rotations with power sources 3x, 3y, 3z which supply controlled currents to the windings 2x, 2y, 2z thereby generating a composition revolving magnetic field in an arbitrary direction. A rotor 5 is rotatably supported through a bearing 4 in the stator 1. |
