Controller structure assembly attachment is in friction machine main shaft. Controller structure assembly can be arranged in the housing of friction machine main shaft or on. For the decoration form of the dispersion obtaining the controller structure assembly for friction machine main shaft Weaving device.
Structure according to the present invention is particularly advantageous, this is because relative to the one or more central authorities setter station usually used such as in the switching cabinet of Weaving device, wiring expense obviously reduces and simplifies. Up to the present need to lay the electric power cable of oneself from friction machine main shaft to switching cabinet and the sensor wire of oneself for each friction machine main shaft. Except very high installation costs, particularly owing to multiple possible interfering source or error source make this be disadvantageous. The disadvantageous effect of electromagnetic compatibility also must be regarded as interfering source, this is because when multiple very long and extend in parallel cable can cause less desirable crosstalk. Particularly the transmission of sensor signal is easily disturbed. In addition, voltage sag and signal reflection can be caused due to very big length of cable. These factors always have impact on controller properties and are also therefore disadvantageous to the speed stability of friction machine main shaft.
According to the present invention, can not be occurred in this form again by these shortcomings of mode that controller structure assembly is directly arranged in friction machine main shaft, resulting in higher speed stability and the wiring expense obviously reduced. Can for controller structure assembly by controller structure assembly is connected on electrical network for running the electric power needed for motorized motions device, multiple friction machine main shaft can be connected on this electrical network simultaneously.
