AC Motor Electric Drive System Comparison

Amasistimu kagesi we-AC asetshenziswa kakhulu ahlanganisa ukumelana nochungechunge lwe-rotor, ukubhuleka okuguquguqukayo (okubuye kwaziwe ngokuthi ukubhuleka okudla amandla), ukulawulwa kwesivinini se-cascade, ukulawulwa kwesivinini sokushaya kwe-rotor, ukulawulwa kwejubane lamabhuleki e-eddy, ukulawulwa kwamandla kagesi we-stator kanye nokulawulwa kwesivinini sokuguqulwa kwemvamisa, njll.Manje ohlelweni lwe-AC electric drive of cranes, ikakhulukazi kunezinhlobo ezintathu ezisetshenziswa kakhulu futhi ezivuthiwe: ukumelana nochungechunge lwe-rotor, ukulawulwa kwamandla kagesi we-stator kanye nokulawulwa kwesivinini sokuguqulwa kwemvamisa.Okulandelayo ukuqhathanisa ukusebenza kwalezi zinhlelo ezintathu zokudlulisa, bheka ithebula elingezansi ukuze uthole imininingwane.

Uhlelo lokulawula ijubane lokumelana nochungechunge lulawulwa ngokuphelele yi-contactor kanye ne-time relay (noma i-PLC), enomthelela omkhulu kusakhiwo semishini kanye nesistimu kagesi, futhi ithinta impilo evamile yesevisi ye-crane.I-contactor ine-arcing engathi sína, imvamisa ephezulu yomonakalo, nomthwalo osindayo wokulungisa.

Ukulawulwa kwengcindezi kanye nesistimu yokulawula isivinini kunenqubo ezinzile yokuqala kanye ne-braking, ukunemba kokulawula isivinini esikhulu, izici zemishini eqinile, umthamo oqinile wokulayisha ngokweqile, ukuguquguquka okuqinile kwemvelo, ukugcinwa okuqinile, kanye nezindleko eziphezulu.

Isistimu yokulawula isivinini sokuguqulwa kwemvamisa inokulawula okuphezulu nokusebenza ngokunemba kokulawula isivinini, futhi ifaneleka kakhulu ezindaweni zokusebenza ezinembayo. Inezidingo zemvelo eziphakeme kakhulu, ukulawulwa komugqa olula, kanye nemisebenzi yokulawula ehlukahlukene inothile futhi iyavumelana nezimo. Kuzoba indlela yokulawula isivinini esikhathini esizayo.
