A device for moving and controlling a weft winding arm in weft feeders for weaving looms, comprising a switched-reluctance motor which is controlled by a first closed loop for speed control, having its own reference variable and its own measured variable, and by a second closed loop for controlling the current that circulates in the phase of the motor, also having its own reference variable and its own measured variable; the reference variable of the first loop corresponds to the rotation rate that the winding arm must assume in order to correctly restore the turns of the weft reserve, and the reference variable of the second loop is constituted by a current value computed by the first control loop.
A device for moving and controlling a weft winding arm in weft feeders for weaving looms, comprising, for the movement of said arm, a switched-reluctance motor, and in that said motor is controlled by a first adjustment closed loop for speed control, which has its own reference variable and its own measured variable, and by a second adjustment closed loop for controlling the current that circulates in the phase of the motor, which also has its own reference variable and its own measured variable.
A method for controlling the rotation of a weft winding arm in weft feeders for weaving looms, comprising the steps of:
