PROBLEM TO BE SOLVED: To provide a spherical motor capable of calculating a rotation direction, a rotation speed, a rotation amount and the like, of a rotor at a high resolution without requiring a holding shaft of a gimbal mechanism, and therefore, without restricting rotation of a rotor and without being affected by magnetism.SOLUTION: In a spherical motor 100 having a rotor 120 that can rotate in an arbitrary direction, movement of the rotor 120 is detected by an optical position sensor 117. |
