A method and circuit arrangement for influencing the wear behavior between a by means of an electric motor is driven to rotate the guide tube and the rolled wire before the direction in a wind generating

摘要

The wear characteristics between rolled wire (1) and the guide tube (5) are continuously monitored via measured current consumption of the tube drive motor (4), which is compared with a given target value. The speed of rotation of the guide is regulated on the basis of the difference between the measured and target values. The appts. includes a device for measuring the motor current. This device is connected to a computer unit. This unit controls the voltage regulator of the motor (4), and is also connected to a device measuring the wire speed.
