Abstract (en)
[origin: EP1057765A2] 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). <IMAGE>
