Umsinga ongenamthwalo ubhekisa kubungakanani bomsinga xaimotoayitsali umthwalo. Ukuze sichaze ubungakanani bomsinga ongenamthwalo, umlinganiselo womsinga ongenamthwalo kumbane olinganisiweyo udla ngokusetyenziswa kuhlalutyo lokuthelekisa. Ngenxa yesi sizathu, siqala ngobudlelwane phakathi komsinga olinganisiweyo kunye nobukhulu.
Xa amandla kunye ne-voltage elinganisiweyo yemoto zifana, i-current elinganisiweyo ixhomekeke ekusebenzeni kakuhle kunye ne-power factor yemoto. Kunokubonwa kwiimeko zobugcisa zeemveliso zeemoto ukuba phantsi kwamandla afanayo kunye ne-voltage elinganisiweyo, ukusebenza kakuhle kunye ne-power factor yeemoto ezine-pole low-speed ezininzi zincinci, kwaye umahluko kwi-power factor yeemoto ezinomahluko omkhulu kumanani e-pole mkhulu kunomahluko ekusebenzeni kakuhle. Ngokusuka kwifomyula yobudlelwane bobungakanani, kunokubonwa ukuba i-current elinganisiweyo yemoto enenani elikhulu lee-pole nayo iya kuba nkulu.
Kwiimoto ezinamandla afanayo kunye neenombolo zeepali ezahlukeneyo umahluko wazo wokusebenza awumkhulu kakhulu, uphawu oluphambili lomahluko kwi-power factor. Uninzi lwamandla angenamthwalo wemoto lusetyenziselwa ukuvelisa intsimi yemagnethi ejikelezayo, kwaye ubungakanani bayo bangoku busondele kakhulu kumandla okukhupha umoya. Ke ngoko, ubungakanani bamandla okukhupha umoya ngokusisiseko bumisela ubungakanani bamandla angenamthwalo.
Kwifomula yokubala yeeparameter zamandla ombane emoto, umsinga wokukhupha umoya unxulumene kakuhle nenani leepali zepali zemoto. Nangona unxulumene nezinye iiparameter, impembelelo yenani leepali zepali iyabonakala ngakumbi. Ke ngoko, phantsi kwemeko efanayo yamandla, ukusebenza kwe-no-load yemoto enesantya esiphantsi Umsinga omkhulu. Ngenxa yobudlelwane phakathi komsinga olinganisiweyo wemoto kunye nobukhulu bemoto yokukhupha umoya, isiseko sethiyori somsinga omkhulu wokukhupha umoya wemoto enepali ezininzi sinokumiselwa ngokusisiseko.
Xa sithatha i-motor engasebenzisi mandla enezigaba ezintathu njengomzekelo, i-no-load current ye-motor ene-2-poles idla ngokuba malunga ne-30% yamandla alinganisiweyo, ngelixa i-no-load current ye-motor ene-8-poles inokufikelela kwi-50-70% yamandla alinganisiweyo; kwezinye ii-motor ezineenjongo ezikhethekileyo, i-no-load current isondele kakhulu kumandla alinganisiweyo.
Ngoko ke, singakwazi nokumisela ngokwemigangatho inqanaba lokusebenza kwemoto ngobukhulu bomsinga ongenamthwalo. Nangona kunjalo, ngenxa yempembelelo efanayo phakathi kweeparamitha ezahlukeneyo zemoto, asinakuvavanya nje enye iparamitha okanye ukusebenza ngokusekelwe kubukhulu beparamitha enye.
