Method and device for automatically adjusting the asynchronous motor for actuation of the weft winding arm in weft feeders for textile machines |
摘要 |
<p>A method for automatically adjusting the asynchronous motor (MO) for moving the weft winding arm (BR) in weft feeders (P) for textile machines, which consists in taking the voltage-frequency characteristic curve (V/F) of the motor as an actuation variable, giving it the role of a numeric index (V/Findex) which is suitable to identify, by choosing it in a set (FC), the characteristic curve that is suitable for the current operating conditions; the controlled variable being constituted by the slip of the motor (MO) that moves said weft winding arm (BR). <IMAGE></p> |
