Motor control system and motor control method
Disclosed are a motor control system and a motor control method that allow the balance of evaluation values in a trade-off relationship to be easily adjusted. The motor control system includes: an inverter (5) that applies AC voltage to a motor (1); a control unit (3, 4) that generates a voltage command for AC voltage in response to a control command; and a feedback unit (6, 7, 8) that applies a correction value to the control unit. The feedback unit estimates a plurality of evaluation values from a state quantity using a plurality of regression formulas, where at least one state quantity (x1, x2) of the motor is an input variable and a plurality of evaluation values (y1, y2) of the motor or a motor-driven object (2) are output variables, calculates an evaluation function with the estimated plurality of evaluation values as arguments, and generates a correction command on the basis of a calculation value resulting from the evaluation function.

Tube Holder for a Bobbin Frame of a Winding Device
The present invention relates to a tube holder (6, 7) for a bobbin frame (1) of a winding device, having a conical tube holder element (23), a retaining element (24), and a spring element (25). The tube holder element (23) is nonrotatably connected to the retaining element (24) via the spring element (25), and the spring element (25) is designed as a spring washer.
Textile machine for producing roving and method for starting the roving production on a corresponding textile machine
A textile machine and associate method are provided for producing a roving, wherein a consolidating means produces a roving having a protective twist from a fiber bundle. A winding device is arranged downstream of the consolidating means in a transport direction of the roving and winds the roving onto a tube driven by a tube drive. An arrangement is disposed to bring the roving leaving the consolidating means during a roving production start procedure into contact with the tube. The arrangement includes a movably mounted suction unit with a suction opening that is configured to suck up the roving during ongoing roving production. Means are provided to bring the roving running between the consolidating means and the suction opening into contact with the tube during ongoing roving production. Means are further provided to cut the roving such that a section of the roving grasped by the suction unit is conveyed away by the suction unit and a section of the roving running between the consolidating means and the tube is wound onto the tube.
