Method and apparatus for controlling the winding of threads and the like onto rotating supports such as reels of yarn and the like

摘要

Apparatus for controlling the alternating movement of a thread guide (6a) which is actuated by an electric motor (4) via means (5a,5b,6) supporting the said thread guide and is intended to wind a thread (7) onto rotating supports (1), comprising an angular transducer (110) for detecting the angular position of the rotor (4a) of the motor (4); a device (120) for vectorial control of the currents supplied to the motor (4); a circuit (130) for controlling the speed of rotation of the rotor (4a), which is connected to the angular transducer (110) and to the vector control circuit (120).
