REJECTION DEVICE OF DISTURBANCES WHEN DYNAMIC BALANCING

摘要

The invention refers to a device for interference rejection that may be used for balancing machines equipped with electro-dynamic transducers with rotation coils, and a duralumin frame with a groove on generators with a length based on the machine overspeed. The input interface has a passive low-pass filter following the linear amplifier. In order to obtain an efficient interference rejection, with an admissible damping of the useful signal of machines with high operating speed, the groove length must be maximal and the filter cutting rate should be minimal. For machines with low operating speeds, the opposite applies.
