MACHINE SLIP AND DIRECTION SENSING USING FLUX GATE SENSOR

MACHINE SLIP AND DIRECTION SENSING USING FLUX GATE SENSOR

A method for determining slip speed information of a shaft. The method comprises receiving, with a signal processor (100), signalling from a flux sensor (22) containing information about both a residual field from an electrical supply to a motor of a driven machine and a magnetic field from one or m...

Zusammenfassung:A method for determining slip speed information of a shaft. The method comprises receiving, with a signal processor (100), signalling from a flux sensor (22) containing information about both a residual field from an electrical supply to a motor of a driven machine and a magnetic field from one or more rotating magnets placed on a rotating component (24) of the driven machine (18). The method further comprises determining, with the signal processor, slip speed information of the shaft based upon a difference between an electrical supply frequency and a slip frequency determined from the signalling received and processed.
