We introduce a new concept of ring-spinning. The model system built on the basis of this concept is capable of producing yarns at a production rate of up to 4 times that of the traditional ring-spinning system. This is a direct result of a ring rotational speed of up to 40,000 rpm. This new concept is termed 'magnetic spinning', and it principally consists of a lightweight rotor suspended magnetically inside a fixed stator; the rotor can spin freely inside the stator. The stator is equipped with four magnetic actuators that always keep the rotor in its central position. The rotor in this configuration replaces the ring and traveller in the traditional spinning system. The system's concept and control analysis are discussed in this paper.
