METHOD AND DEVICE PROCESS CONTROL OF ROTATING MACHINES Russian patent published in 2012 - IPC H02K15/00 G01R31/34 

FIELD: electricity.

SUBSTANCE: rotating machine contains at least one rotating component and least one fixed component located so that between parts of at least such elements only certain gap is created having measured radial dimension and measured magnetic flux which is generated in the gap at least partially due to relative movement of fixed and rotating components. According to this invention, gap measurement unit contains at least one device for gap size measuring which device is configured with possibility to determine capacity change using proximity determination probe and at least one device for measuring gap magnetic flux configured with possibility to determine voltage change by means of magnetic flux measuring, where at least one device for gap size measuring and one device for gap magnetic flux measuring are synchronised so that input signal of gap size and input signal of gap magnetic flux are generated virtually simultaneously.

EFFECT: providing operative and effective measurement of rotating machines working gap and magnetic flux with simultaneous support of time and place synchronisation of specified parameters measurement, lowering capital, mounting and operational costs, improvement of reliability of rotating machines such as generators and turbine generators, and reducing their emergency outages.
