Mphamvu zamagalimoto ziyenera kusankhidwa molingana ndi mphamvu zomwe zimafunidwa ndi makina opanga, ndikuyesera kuti injiniyo iziyenda pansi pa katundu wovotera.Posankha, muyenera kulabadira mfundo ziwiri zotsatirazi:

① Ngati mphamvu yagalimoto ndi yaying'ono kwambiri.Padzakhala chodabwitsa cha "ngolo yaying'ono yokokedwa ndi akavalo", zomwe zimapangitsa kuti injiniyo ikhale yodzaza kwa nthawi yayitali.Kutsekemera kwake kumawonongeka chifukwa cha kutentha.Ngakhale galimoto inapsa.

② Ngati mphamvu yagalimoto ndi yayikulu kwambiri.Padzakhala chodabwitsa cha "ngolo yaikulu yokokedwa ndi akavalo".Mphamvu zake zamakina zotulutsa sizingagwiritsidwe ntchito mokwanira, ndipo mphamvu yamagetsi ndi magwiridwe antchito sizokwera, zomwe sizongosangalatsa kwa ogwiritsa ntchito ndi gridi yamagetsi.Ndipo zidzawononganso magetsi.

Chomwe chimagwiritsidwa ntchito kwambiri ndi njira yofananira posankha mphamvu yagalimoto.Zomwe zimatchedwa fanizo.Zimafaniziridwa ndi mphamvu ya galimoto yamagetsi yomwe imagwiritsidwa ntchito m'makina opangira ofanana.

Njira yeniyeni ndi: kumvetsetsa injini yamagetsi yomwe imagwiritsidwa ntchito ndi makina opangira ofanana a unit iyi kapena mayunitsi ena oyandikana nawo, ndiyeno sankhani injini yamphamvu yofananira kuti muyese mayeso.Cholinga cha mayesowa ndikuwonetsetsa kuti injini yosankhidwa ikugwirizana ndi makina opanga.

Njira yotsimikizira ndi: pangani injini kuyendetsa makina opanga kuti ayendetse, kuyeza momwe injini ikugwirira ntchito ndi ammeter yochepetsera, ndikuyerekeza zomwe zayezedwa ndi zomwe zidavotera zomwe zalembedwa pa dzina la mota.Ngati zenizeni zomwe zikugwira ntchito pamakina amagetsi amagetsi sizili zosiyana kwambiri ndi zomwe zidalembedwa pa ndulu.Zimasonyeza kuti mphamvu ya galimoto yosankhidwa ndi yoyenera.Ngati ntchito yeniyeni ya injiniyo ili pafupi ndi 70% yotsika kuposa yomwe ili pakali pano yomwe ili pa nameplate.Zimasonyeza kuti mphamvu ya galimotoyo ndi yaikulu kwambiri, ndipo galimoto yokhala ndi mphamvu zochepa iyenera kusinthidwa.Ngati mphamvu yomwe ikugwira ntchito ya injiniyo ndi yokulirapo kuposa 40% kuposa yomwe idayikidwa pa dzina.Zimasonyeza kuti mphamvu ya galimotoyo ndi yaying'ono kwambiri, ndipo galimoto yokhala ndi mphamvu yaikulu iyenera kusinthidwa.

Ndiwoyenera kuwongolera mgwirizano pakati pa mphamvu yovotera, liwiro lovotera ndi torque yovotera ya mota ya servo, koma mtengo weniweni wa torque uyenera kutengera muyeso weniweni.Chifukwa cha vuto la kusintha kwamphamvu kwa mphamvu, zoyambira nthawi zambiri zimakhala zofanana, ndipo padzakhala kuchepa kobisika.

Pazifukwa zamapangidwe, ma mota a DC ali ndi zovuta izi:

(1) Maburashi ndi ma commutators amafunika kusinthidwa pafupipafupi, kukonza kumakhala kovuta, ndipo moyo wautumiki ndi waufupi;(2) Chifukwa cha kutentha kwa injini ya DC, zimakhala zovuta kugwiritsa ntchito malo ovuta omwe ali ndi mpweya woyaka komanso wophulika;(3) Kapangidwe kake ndi kovutirapo, ndikovuta kupanga mota ya DC yokhala ndi mphamvu yayikulu, liwiro lalikulu komanso voteji yayikulu.

Poyerekeza ndi ma mota a DC, ma mota a AC ali ndi izi:

(1)Kapangidwe kolimba, ntchito yodalirika, kukonza kosavuta;(2) Palibe spark yosinthira, ndipo itha kugwiritsidwa ntchito m'malo ovuta omwe ali ndi mpweya woyaka ndi kuphulika;(3) Ndiosavuta kupanga injini yamphamvu yayikulu, yothamanga kwambiri komanso yothamanga kwambiri ya AC.

Chifukwa chake, kwa nthawi yayitali, anthu amayembekeza kusintha mota ya DC ndi mota ya AC yosinthika nthawi zambiri, ndipo kafukufuku wambiri ndi ntchito zachitukuko zachitika pakuwongolera liwiro la mota ya AC.Komabe, mpaka zaka za m'ma 1970, kafukufuku ndi chitukuko cha kayendedwe ka liwiro la AC sikunathe kupeza zotsatira zokhutiritsa, zomwe zimalepheretsa kutchuka ndi kugwiritsa ntchito njira yoyendetsera liwiro la AC.Zilinso pachifukwa ichi kuti ma baffles ndi ma valves ayenera kugwiritsidwa ntchito kuti asinthe liwiro la mphepo ndikuyenda mumagetsi oyendetsa magetsi monga mafani ndi mapampu amadzi omwe amagwiritsidwa ntchito kwambiri popanga mafakitale ndipo amafuna kuyendetsa mofulumira.Njirayi sikuti imangowonjezera zovuta za dongosolo, komanso zimabweretsa mphamvu zowonongeka.
