Zvimwe chetemota ine zvikamu zvitatuinogona kubatanidzwa nekubatanidza kwetriangle, zvinoenderana nevoltage yakaderera; Inogonawo kubatanidzwa zvichienderana nenzira yekubatanidza nyeredzi, zvinoenderana nevoltage yakakwirira; Voltage yakakwira inopetwa katatu kupfuura mudzi we square root wevoltage yakaderera. Semuenzaniso, mota ye380V ine connection yetriangle, kana yakabatana neconnection yenyeredzi, voltage inoenderana nayo i660V. Kubatana kwacho kunofanirwa kuenderana nevoltage yemagetsi.
Mota ine nyeredzi haiburitse kutenderera kweropa mukati, izvo zviri nani pane kubatana kwetriangular.
Nekuti kutenderera kwezvikamu zvitatu hakugone kuenzana zvakakwana, pane musiyano mudiki nguva dzose muMota ine zvikamu zvitatuvoltage, iyo inoumba kutenderera mukati metriangle, zvichikonzera kudzikiswa kwekupisa kwemota uye kushanda zvakanaka. Kubatana kwetriangle kunoitwawo nekuda kwezvikonzero zvekare, ndiko kuti, iyo inonzi star-triangle start, star-triangle start inogona kuderedza zvinobudirira kutanga kwemagetsi, asi inoderedza torque yekutanga, saka inogona kushandiswa chete kana paine mutoro wakareruka kana pasina mutoro wekutanga.
Tinoona kuti mota yepombi yefeni inogona kutanga nenyeredzi-triangle, asi hapana kutanga kwenyeredzi-triangle pacrane, kusimudza kunowanzo tangwa nekudzivirira kwerotor series, sei uchiita dambudziko rakawanda kudaro, pane chikonzero. Ehe, mamiriro aripo ekuchinja frequency anotanga akagadzirisa matambudziko akadaro zvachose.
Pasinei nehurongwa hwewaya nhatu kana hwemawaya mana (isina pasi), Angle yemagetsi iri pakati pemavoltage matatu ine musiyano wechikamu che120 degrees pasi pemamiriro akanaka. Zvinofungidzirwa kuti nekuda kwekupindirana kwenguva nenguva, maharmoniki e3N anogadzirwa muchikamu chekutenderera kwechiteshi chemutoro, 3N*120=360N, zvichiratidza kuti chikamu chemagetsi che3N chechikamu chetatu chakafanana chaizvo, kana amplitude yakafanana, maharmoniki e3N emapoka matatu emagetsi emutsara achadzimwa zvachose, kureva kuti, hapana maharmoniki akawanda e3 muvoltage iri pakati pemitsara.
Pakubatana kwetriangle, ma "3N harmonic currents" ari pamusoro apa ari muchikamu chimwe chete anopfupikiswa mutriangle iyi uye anochengetwa mutriangle iyi kuti agadzire kutenderera kusingaperi. Saka, kana paine ma "harmonics", kubatana kwetriangle kana nyeredzi kunogona kusarudzwa zvichienderana nekuti ma "3N harmonics" anogoneka here muvoltage kana current.
