Inkqubo yolawulo lweimotoyenziwe ngeeswitshi, iifusi, iicontactor eziphambili nezincedisayo, iirelayini, ubushushu, izixhobo zokungenisa, njl.njl., nto leyo enzima kakhulu. Zininzi iintlobo zeempazamo, kwaye kudla ngokufuneka ukuhlalutya nokusombulula iingxaki ngoncedo lwemizobo yokulawula.
Ngokwesiqhelo, kufuneka uqaphele ukugcina ingaphakathi nangaphandle kwebhokisi yokulawula icocekile kwaye yomile, ngaphandle kwamanzi okanye amabala eoyile. Rhoqo (ngeveki) sebenzisa ifeni encinci ukuvuthuza uthuli kwizakhi kunye neeterminals kunye nemigca ebhokisini, okanye sebenzisa ibrashi efakwe kwisicoci sombane ukuze uyihlambe, ukuze ingachaphazeli ukusebenza okanye ukugquma kwe-contactor kunye ne-relay. Kwiibhokisi zokulawula ezine-drying resistor, ngokubanzi musa ukuyicima i-heating switch ngokuthanda kwakho. Ibhokisi kufuneka ibekwe phantsi ngokuthembekileyo ukuthintela ukutshayiswa ngumbane.
Jonga ukuqina kwentambo kunye nezikrufu ebhokisini rhoqo (nyanga zonke) ukuthintela ukuba intambo kunye nezikrufu zingakhululeki. Jonga ukuba izinto ezifana neeswitshi, iicontactors, iirelay, njl.njl. zonakele okanye zitshile, kwaye nokuba imeko yokusebenza kwenxalenye nganye kunye nemisebenzi yokuqala, yokuma, kunye neyokutshixa iqhelekile. Gcina uqhagamshelwano oluhambayo nolungashukumiyo lwecontactor luvaliwe kwaye lunxibelelana kakuhle ukuze uphephe ukutsha kwemoto ngenxa yonxibelelwano olubi. Ukuba umphezulu woqhagamshelwano ulungile kwaye umnyama nje, ungawusula ngelaphu elirhabaxa. Musa ukupolisha ngokulula umaleko we-alloy omelana nobushushu kumphezulu, kungenjalo kuya kunciphisa ubomi boqhagamshelwano; Ukuba umphezulu woqhagamshelwano ucocwe kakhulu, ungasebenzisa iphepha lesanti "0" ukuze ulithambise. Ii-contacts ezihambayo nezinganyakaziyo kufuneka zigcine unxibelelwano oluhambelanayo okanye umphezulu, kungekhona unxibelelwano oluchanekileyo. Imeko yoqhagamshelwano ingajongwa ngokubeka iphepha phakathi kwee-contacts ezihambayo nezinganyakaziyo. Ukuba ayibotshelelwanga ngokuqinileyo xa itsalwa, oko kuthetha ukuba unxibelelwano okanye ispring kufuneka ilungiswe okanye itshintshwe. Eli nqaku kufuneka lithathwe nzulu. Kwiimeko ezincinci, unxibelelwano olungalunganga luya kuvelisa ukumelana okukhulu konxibelelwano (umbane), oko kuthetha ukuba umthwalo uyanda, okubangela ukuba i-relay yokukhusela ukugqithisa ikhubeke. Kwiimeko ezinzima, kuya kubangela ukuba imoto isebenze ngendlela engenasigaba kwaye itshiswe.
Xa utshintsha iirelay kunye neecontactor, kufuneka uqwalasele i-voltage esebenzayo ye-electromagnetic coil ukuze uphephe ukutsha kwe-coil ngenxa yokutshintshwa okungafanelekanga. Ngokubanzi, kukho i-24V, i-220V kunye ne-380V. Kwi-time relay, ukongeza ekuqwalaseleni iimfuno ze-coil voltage, kufuneka ucacise iyunithi yohlengahlengiso lwexesha (iyure, umzuzu, isekhondi) kunye nobubanzi be-time relay; nokuba i-set current ye-thermal relay ifanelekile kwaye ifanelekile na.
Kwiimoto eziqaliswayo kusetyenziswa indlela ye-star-delta (Y-△) (ukulibaziseka kokuguqula malunga nemizuzwana emi-5), jonga ukuba ukuqala kokuguqula kuqhelekile na. Ngokwesiqhelo, abavelisi banemigaqo engqongqo kumjikelo wokuqala wemoto (oko kukuthi inani lokuqalisa ngomzuzu), kwaye kuya kubakho iileyibhile zesilumkiso kwibhokisi yokulawula ukuqala ukukhumbuza abasebenzisi ukuba bathintele ukuba imoto ingonakali ngenxa yokuqalisa rhoqo. Kwangaxeshanye, kukwathintela ezinye izinto zombane kwibhokisi yokulawula ukuqala (ezifana nee-reactors zokuqala, njl.njl.) ekufudumaleni nasekutshiseni. Ke ngoko, kwiinkqubo zolawulo lweemoto eziqala kwaye zima rhoqo okanye ezinee-currents ezinkulu, umjikelo wokuhlola nokugcina kufuneka ufinyezwe. Jonga rhoqo umsebenzi wokhuseleko lwe-thermal overload relay (ungajika inkqubo ebomvu encinci ecaleni kwayo) kwaye ixabiso layo lesenzo elibekiweyo akufuneki lidlule ixabiso langoku elilinganisiweyo kwi-nameplate yemoto ukuqinisekisa ukuba inokudlala indima yokukhusela overload.
