PURPOSE: To precisely correct rotation of an object around the axis by mounting a first motor to a mechanical transmission device in a second motor. CONSTITUTION: For orienting an object A around an axis R1 , a first motor M1 is driven, so that a stator 24 is kept stationary, a rotor 50 is rotated, and third - fifth conical gears 51, 70, 71 and a plate 73 are rotationally driven sequentially. In this process, a fork type joint C is kept stationary, and two-directional drive is disconnected. For orienting the object A around the axis R2 , a second motor M2 is driven, so that first and second conical gears 20, 27 and the fork type joint C are driven, and lastly, the object A is driven. In addition, a small body member 22 and the stator 24 of the first motor M1 are rotationally driven by means of the second motor M2 . In this process, the rotor 50 magnetically connected to the stator 24 is integrally rotated with the stator 24, and the third - fifth conical gears 51, 70, 71 are also rotationally driven. |
