Ugesi ongenamthwalo ubhekisela kusayizi wamandla kagesi laphoinjiniakusikhiphi umthwalo. Ukuze sichaze usayizi wamanje ongenayo umthwalo, isilinganiso samanje ongenayo umthwalo kumanje olinganiselwe sivame ukusetshenziselwa ukuhlaziya okuqhathanisayo. Ukuze sifeze lokhu, siqala ngobudlelwano phakathi kwamanje olinganiselwe nosayizi.
Uma amandla alinganisiwe kanye ne-voltage yemoto kufana, ugesi olinganisiwe uncike ekusebenzeni kahle kanye ne-power factor yemoto. Kungabonakala ezimweni zobuchwepheshe zemikhiqizo yemoto ukuthi ngaphansi kwamandla alinganisiwe kanye nezimo ze-voltage ezilinganisiwe, ukusebenza kahle kanye ne-power factor yama-motor ane-pole low-speed amaningi kuncane kakhulu, kanti umehluko ku-power factor yama-motor anomehluko omkhulu ezinombolo ze-pole mkhulu kunomehluko ekusebenzeni kahle. Ngokusebenzisa nje ifomula yobudlelwano bosayizi, kungatholakala ukuthi ugesi olinganisiwe wemoto onenani elikhulu lezingodo nawo uzoba mkhulu.
Kuma-motor anamandla afanayo nezinombolo ezihlukene zama-pole umehluko wawo wokusebenza kahle awumkhulu kakhulu, ukubonakaliswa okuyinhloko umehluko ku-power factor. Iningi lamandla angenamthwalo wemoto lisetshenziselwa ukukhiqiza insimu yamagnetic ejikelezayo, futhi usayizi wamanje wayo useduze kakhulu nomsinga wokuvuselela. Ngakho-ke, usayizi wamandla okuvuselela ngokuyisisekelo unquma usayizi wamandla angenamthwalo.
Efomini yokubala yamapharamitha wamanje wemoto, ugesi wokuvuselela uhlobene kahle nenani lamapharamitha e-pole emoto. Nakuba uhlobene nezinye ipharamitha, ithonya lenani lamapharamitha e-pole lisobala kakhulu. Ngakho-ke, ngaphansi kwesimo samandla esifanayo, ukusebenza kwe-no-load kwemoto enesivinini esiphansi Ugesi wamanje mkhulu kakhulu. Ngokubheka ubudlelwano phakathi kogesi olinganisiwe wemoto nosayizi wemoto wokuvuselela, isisekelo sethiyori sogesi omkhulu ongenamthwalo wemoto enamapharamitha amaningi singanqunywa ngokuyisisekelo.
Uma sithatha injini engenazo izigaba ezintathu njengesibonelo, amandla kagesi angenazo imithwalo yemoto enama-pole amabili ngokuvamile angaba ngu-30% wamandla kagesi alinganisiwe, kuyilapho amandla kagesi angenazo imithwalo yemoto enama-pole angu-8 angafinyelela ku-50-70% wamandla kagesi alinganisiwe; kwamanye ama-motor anezinjongo ezikhethekile, amandla kagesi angenazo imithwalo asondele kakhulu kumandla kagesi omthwalo.
Ngakho-ke, singanquma futhi ngokwekhwalithi izinga lokusebenza kwemoto ngosayizi wamanje ongenayo umthwalo. Kodwa-ke, ngenxa yethonya elihambisanayo phakathi kwamapharamitha ahlukahlukene emoto, asikwazi nje ukuhlola elinye ipharamitha noma ukusebenza ngokusekelwe kusayizi wepharamitha eyodwa.
