Noma yimuphi umkhiqizo kagesi, okuhlanganisa nemikhiqizo yezimoto, vele, ibeka i-voltage elinganiselwe ngokusebenza kwawo okuvamile.Noma yikuphi ukuchezuka kwamandla kagesi kuzodala imiphumela emibi ekusebenzeni okuvamile kwento esebenza ngogesi.

Okokusebenza okusezingeni eliphezulu, kusetshenziswa amathuluzi okuvikela adingekayo.Uma amandla kagesi engajwayelekile, ugesi uyanqanyulwa ukuze uvikeleke.Kumathuluzi anembe kakhulu, amandla kagesi angashintshi asetshenziselwa ukulungiswa.Imikhiqizo yezimoto, ikakhulukazi Emikhiqizweni yezimoto zezimboni, ithuba lokusebenzisa idivayisi ye-voltage engaguquki mancane kakhulu, futhi kunezimo eziningi zokuvikela ukucisha ugesi.

Enjini yesigaba esisodwa, kunezimo ezimbili kuphela zamandla kagesi aphezulu kanye ne-voltage ephansi, kanti enjini yezigaba ezintathu, kunenkinga yebhalansi kagesi.Ukubonakaliswa okuqondile komthelela walokhu kuchezuka kwama-voltage amathathu ukukhuphuka kwamanje noma ukungalingani kwamanje.

Izimo zobuchwepheshe zemoto zikhomba ukuthi ukuchezuka okuphezulu nangaphansi kwe-voltage elinganiselwe yemoto angeke kudlule u-10%, futhi i-torque ye-motor ilingana nesikwele se-voltage ye-motor terminal.Lapho i-voltage iphezulu kakhulu, umgogodla wensimbi we-motor uzoba sesimweni sokugcwala kazibuthe, futhi i-stator current izokwanda.Kuzoholela ekushiseni okungathi sína kokuvunguza, ngisho nenkinga yekhwalithi yokushiswa kokuqina;futhi endabeni ye-voltage ephansi, enye iwukuthi kungase kube nezinkinga ngokuqala kwe-motor, ikakhulukazi ye-motor egijima ngaphansi komthwalo, ukuze ihlangabezane nokugijima komthwalo we-motor, I-current kumele futhi yandiswe, futhi umphumela wokwanda kwamanje futhi ukushisa ngisho nokushiswa kwama-windings, ikakhulukazi ekusebenzeni kwe-low-voltage yesikhathi eside, inkinga inkulu kakhulu.

I-voltage engalingani ye-motor yezigaba ezintathu iyinkinga evamile yokunikezwa kwamandla.Lapho i-voltage ingalingani, nakanjani izoholela ekungeneni kwemoto okungalingani.Ingxenye engalungile yokulandelana kwe-voltage engalingani idala insimu yamagnetic kugebe lomoya wemoto eliphikisana nokuphenduka kwe-rotor.Ingxenye encane yokulandelanisa okunegethivu ku-voltage ingase ibangele ukuthi i-current through the winding ibe nkulu kakhulu kunalapho i-voltage ibhalansisiwe.Imvamisa yamanje egeleza emigoqweni ye-rotor cishe iphindwe kabili imvamisa elinganisiwe, ngakho-ke umphumela wamanje wokucindezela emigodleni ye-rotor wenza ukwanda kokulahlekelwa kwe-rotor windings kukhulu kakhulu kune-stator windings.Ukukhuphuka kwezinga lokushisa kwe-stator winding kuphakeme kunalokho lapho kusebenza ku-voltage elinganiselwe.

Lapho i-voltage ingalingani, i-torque yesitolo, i-torque encane kanye ne-torque enkulu ye-motor konke kuzoncishiswa.Uma ukungalingani kwamandla kagesi kubi kakhulu, injini ngeke isebenze kahle.

Lapho i-motor igijima ngomthwalo ogcwele ngaphansi kwe-voltage engalingani, njengoba isiliphu sikhuphuka ngokunyuka kokulahlekelwa okwengeziwe kwe-rotor, isivinini sizokwehla kancane ngalesi sikhathi.Njengoba i-voltage (yamanje) ingalingani inyuka, umsindo nokudlidliza kwemoto kungase kwande.Ukudlidliza kungalimaza injini noma lonke uhlelo lokushayela.

Ukuze kukhonjwe ngempumelelo imbangela yamandla kagesi angalingani, ingenziwa ngokusebenzisa ukutholwa kwamandla kagesi noma ukushintshashintsha kwamanje.Imishini eminingi ifakwe ithuluzi lokuqapha amandla kagesi, elingahlaziywa ngokuqhathanisa idatha.Esimeni lapho kungekho divayisi yokuqapha, ukutholwa okujwayelekile noma ukulinganisa kwamanje kufanele kusetshenziswe.Endabeni yokuhudula okokusebenza, ulayini wokuphakelwa kwamandla wezigaba ezimbili ungashintshwa ngokungafanele, ushintsho lwamanje lungabonwa, futhi ibhalansi kagesi ingahlaziywa ngokungaqondile.
