Abstract (en)

[origin: EP2341170A1] Drive unit (1) for weaving looms, of the type comprising a first electric motor (2) driving the moving members of the loom (T) which cause the insertion and beating of the weft, a second electric motor (3) driving the weaving machine (A) which causes the opening/closing movement of the warp yarns for shed forming and an electric-axis control system to maintain the synchronisation and/or the desired degree of phase displacement between said moving members of the loom (T) and said weaving machine (A). Said first and second motor (2, 3) are mounted coaxially and are both provided with a second power takeoff, said second power takeoffs being adjacent and mutually connected through an electromagnetic connection, disengageable by energising the electromagnet.
