Abstract
An electromagnet exhibits in its energization curve (I=f(t)) a characteristic feature or indicator, for example, in the form of a dip (,) in the energization current. This indicator is used to control the operation of the magnet, for example, to synchronize its operation with that of another magnet. In a loom the operation of a weft stop magnet positioned next to a weft prewinder may be synchronized with the operation of a solenoid driving a valve that supplies air to the main weft insertion nozzle and/or relay nozzles. A magnet may also be controlled with reference to rated operation values so that its actual operation value coincides with the rated value or values or at least is maintained within a permissible tolerance range of rated values. The control takes place in closed loop fashion, for example, through the main loom control.
