PURPOSE:A small-sized rotary ring which has a simple structure and is easily attached to a fine spinning frame, consisting of a ring rotating member provided with a rotor magnet at the bottom of a collar and a ring fixing member provided with an armature coil opposing the rotor magnet. CONSTITUTION:The rotary ring 1 consists of the ring rotating member 2 and the ring fixing member 3, and the ring rotating member is supported on the ring fixing member through the ultra-high speed angular ball bearing 11 in such a way that the ring-shaped armature coil 9 is arranged at a position opposing the rotor magnet 8. The sensor 10 set in the vicinity of the armature coil 9 and the rotor magnet 8 is used for controlling rotation of the ring rotating member 2 and speed of rotation. |
