1. Kuyamba mwachindunji
Kuyamba mwachindunji ndi njira yolumikizira mwachindunjistatorkupotoza kwamota yamagetsiku magetsi ndi kuyamba pa voteji yovomerezeka. Ili ndi mawonekedwe a torque yoyambira yapamwamba komanso nthawi yochepa yoyambira, komanso ndiyo njira yosavuta, yotsika mtengo, komanso yodalirika yoyambira. Mukayamba pa voteji yonse, mphamvu yamagetsi imakhala yayikulu ndipo torque yoyambira si yayikulu, zomwe zimapangitsa kuti ikhale yosavuta kuyigwiritsa ntchito komanso kuyamba mwachangu. Komabe, njira yoyambira iyi ili ndi zofunikira zambiri pakukula kwa gridi ndi katundu, ndipo ndi yoyenera kwambiri ma mota oyambira pansi pa 1W.
2.Kuyamba kwa kukana kwa magalimoto
Kuyambitsa kukana kwa ma mota ndi njira yochepetsera kuyambika kwa magetsi. Pa nthawi yoyambira, resistor imalumikizidwa mu mndandanda mu dera lozungulira la stator. Pamene mphamvu yoyambira ikudutsa, kutsika kwa magetsi kumapangidwa pa resistor, zomwe zimachepetsa magetsi omwe amagwiritsidwa ntchito pastatorkuzunguliza. Izi zitha kukwaniritsa cholinga chochepetsa mphamvu yoyambira.
3.Kuyambira kwa cholumikizira chodzigwirizanitsa
Kugwiritsa ntchito njira yochepetsera mphamvu zamagetsi pogwiritsa ntchito ma autotransformer sikungokwaniritsa zosowa za magalimoto osiyanasiyana, komanso kupeza mphamvu yoyambira yayikulu. Ndi njira yoyambira yochepetsera mphamvu zamagetsi yomwe imagwiritsidwa ntchito kwambiri poyambitsa ma mota akuluakulu. Ubwino wake waukulu ndikuti mphamvu yoyambira imakhala yayikulu. Pamene mphamvu yozungulira ili pa 80%, mphamvu yoyambira imatha kufika 64% ya mphamvu yoyambira mwachindunji, ndipo mphamvu yoyambira imatha kusinthidwa kudzera mu pompo. Akaunti yovomerezeka ya "Mechanical Engineering Literature", malo opangira mafuta a mainjiniya!
4. Kuyamba kwa Kuchepetsa Kupsinjika kwa Nyenyezi ya Delta
Kwa injini ya agologolo yopanda mphamvu yokhala ndi ntchito yabwinobwinostatorKuzungulira kolumikizidwa mwanjira ya triangle, ngati kuzungulira kwa stator kwalumikizidwa mu mawonekedwe a nyenyezi panthawi yoyambira kenako kulumikizidwa mu mawonekedwe a triangle mutayamba, kumatha kuchepetsa mphamvu yoyambira ndikuchepetsa mphamvu yake pa gridi yamagetsi. Njira yoyambira iyi imatchedwa star delta decompression starting, kapena kungoyambira nyenyezi ya delta (y&starting).
Mukagwiritsa ntchito njira yoyambira ya star delta, mphamvu yoyambira ndi gawo limodzi mwa magawo atatu okha a njira yoyambira mwachindunji pogwiritsa ntchito njira yolumikizira ya triangle. Mukayamba kugwiritsa ntchito star delta, mphamvu yoyambira ndi nthawi 2-2.3 zokha. Izi zikutanthauza kuti mukagwiritsa ntchito star delta yoyambira, mphamvu yoyambira imachepetsedwanso kufika gawo limodzi mwa magawo atatu a momwe inalili poyambira kugwiritsa ntchito njira yolumikizira ya triangle.
Yoyenera malo omwe palibe katundu wolemera kapena wopepuka woyambira. Ndipo poyerekeza ndi choyambira china chilichonse chopanda vacuum, kapangidwe kake ndi kosavuta ndipo mtengo wake ndi wotsika mtengo kwambiri.
Kuphatikiza apo, njira yoyambira ya star delta ilinso ndi ubwino, womwe ndi wakuti pamene katundu ndi wopepuka, ukhoza kulola mota kugwira ntchito motsatira njira yolumikizira nyenyezi. Pakadali pano, mphamvu yovotera ndi katundu wovotera zitha kufananizidwa, zomwe zingathandize kuyendetsa bwino mota ndikusunga magetsi.
5. Chiyambi cha Frequency converter (chiyambi chofewa)
Chosinthira ma frequency ndi chipangizo chowongolera mota chapamwamba kwambiri paukadaulo, chogwira ntchito mokwanira, komanso chogwira ntchito bwino kwambiri pakuwongolera magalimoto amakono. Chimasintha liwiro ndi mphamvu ya mota posintha ma frequency a gridi yamagetsi. Chifukwa cha kugwiritsidwa ntchito kwa ukadaulo wamagetsi ndi ukadaulo wa microcomputer, mtengo wake ndi wokwera ndipo zofunikira za akatswiri okonza zinthu nazonso ndizokwera. Chifukwa chake, chimagwiritsidwa ntchito makamaka m'magawo omwe amafunikira malamulo owongolera liwiro komanso zofunikira zowongolera liwiro.
