Indandatho yokumisa isisekelo MTE01082-01

Indandatho yokumisa idlala indima ebalulekile ekuvimbeleni ukwakheka nokuqongelela kwe-shaft voltage kanye ne-bearing currents—izinkinga ezimbili ezivamile kodwa ezibhubhisayo emishinini kagesi ejikelezayo njengezinjini kanye namajeneretha. I-shaft voltage ngokuvamile ivela emiphumeleni yokungeniswa kwe-electromagnetic ngaphakathi komshini, njengokusatshalaliswa kwe-magnetic flux okungalingani ku-stator core, ukuhlanganiswa kwe-capacitive phakathi kwe-stator windings kanye ne-rotor, noma ama-voltage asele avela kuma-variable frequency drives (VFDs) anika amandla izinjini eziningi zezimboni zesimanje. Lapho le voltage inqwabelana kulo lonke i-shaft, ingadlula amandla e-dielectric efilimu yokugcoba kuma-bearing omshini. Uma lo mkhawulo usuweqiwe, kuvela ukukhishwa, okudala lokho okwaziwa ngokuthi i-bearing current. Lawa ma-currents, nakuba evame ukuba mancane ngobukhulu, agxile kakhulu, futhi ngokuhamba kwesikhathi, agugula imigwaqo yokugibela ama-bearing kanye nezinto ezigoqayo, okuholela ekuqhekekeni, ekuqhekekeni, nasekuhlulekeni kwe-bearing ngaphambi kwesikhathi. Ezimweni ezimbi kakhulu, lokhu kungaholela ekungasebenzi komshini okungalindelekile, ukulungiswa okubizayo, ngisho nomonakalo wesibili emishinini exhunyiwe emgqeni wokukhiqiza.
