Ngaphandle kwama-motor amancane ikakhulukazi, ama-motor windings amaningi adinga izinqubo zokucwilisa nokomisa ukuze kuqinisekiswe ukusebenza kwe-insulation yama-motor windings futhi ngesikhathi esifanayo kunciphisa umonakalo kuma-windings lapho injini isebenza ngomphumela wokuphulukisa wama-windings.
Kodwa-ke, uma iphutha likagesi elingenakulungiseka lenzeka emaphethelweni enjini, ama-windings kufanele acutshungulwe kabusha, futhi ama-windings okuqala azosuswa.Ezimweni eziningi, ama-windings azokhishwa ngokushiswa, ikakhulukazi ezitolo zokulungisa izimoto., kuyindlela ethandwa kakhulu.Ngesikhathi senqubo yokushiswa, umgogodla we-iron uzoshiselwa ndawonye, futhi amashidi ensimbi agxotshiwe azokwenziwa i-oxidized, okulingana nobude obusebenzayo be-motor core uba mncane kanye nokungena kazibuthe kwe-iron core kwehla, okuholela ngokuqondile I-current no-load ye-motor iba mkhulu, futhi umthamo wamanje uzokhuphuka kakhulu ezimweni ezinzima.
Ukuze ugweme le nkinga, ngakolunye uhlangothi, izinyathelo zithathwa ekukhiqizeni injini ukuze kuqinisekiswe ikhwalithi nokuthembeka kwama-motor windings.Ngakolunye uhlangothi, ama-windings akhishwa ngezinye izindlela lapho ama-motor windings elungiswa.Lesi isilinganiso esithathwe izitolo eziningi zokulungisa ezisezingeni.Kuyadingeka futhi ezidingweni zokuvikelwa kwemvelo.
Ngokuvamile, kuncike emandleni emoto.Umthamo wamanje ongalayishiwe wamamotho amancane ungafinyelela ku-60% wamanje olinganiselwe, noma ngaphezulu.Amandla wamanje ongalayishiwe wamamotho amakhulu ngokuvamile angaba ngu-25% kuphela wamanje akaliwe.
Ubudlelwano phakathi kokuqala ukusebenza kwamanje nokujwayelekile kwemotho enezigaba ezintathu.Ukuqala okuqondile izikhathi ezingu-5-7, ukuqala kwe-voltage encishisiwe izikhathi ezingu-3-5, kanti okwamanje i-motor stall yesigaba sesithathu cishe izikhathi ezingu-7.Izinjini zesigaba esisodwa cishe izikhathi eziyi-8.
Lapho i-asynchronous motor isebenza ngaphandle komthwalo, i-current egeleza phakathi kwesigaba sesithathu se-stator ibizwa ngokuthi i-no-load current.Iningi lamanje elingalayishi lisetshenziselwa ukukhiqiza inkambu kazibuthe ezungezayo, ebizwa ngokuthi i-no-load excitation current, okuyingxenye esebenzayo ye-no-load current.Kukhona nengxenye encane ye-no-load current esetshenziswa ukukhiqiza ukulahleka kwamandla okuhlukahlukene lapho injini isebenza ngaphandle komthwalo.Le ngxenye iyingxenye esebenzayo ye-no-load current, futhi ingashaywa indiva ngoba ibala ingxenye encane.Ngakho-ke, i-no-load current ingabhekwa njengeyamanje esebenzayo.
Kusukela kulo mbono, kuncane kakhulu, kungcono, ukuze isici samandla se-motor sithuthukiswe, okulungele ukunikezwa kwamandla kugridi.Uma umthamo wamanje ongenamthwalo mkhulu, njengoba indawo ephethe umqhubi we-stator winding iqinisekile futhi yamanje evunyelwe ukudlula iqinisekile, okwamanje okusebenzayo okuvunyelwe ukugeleza kuma-conductor kungancishiswa kuphela, futhi umthwalo injini ingashayela izoncishiswa.Lapho ukuphuma kwemoto kuncishisiwe futhi umthwalo mkhulu kakhulu, ama-windings avame ukushisa.
Noma kunjalo, i-current no-load ayikwazi ukuba yincane kakhulu, ngaphandle kwalokho izothinta ezinye izakhiwo ze-motor.Ngokuvamile, amandla amanje angalayishiwe amamotho amancane acishe abe ngu-30% kuya ku-70% wamanje akaliwe, kanti amandla amanje angalayishiwe amamotho amakhulu naphakathi nendawo angaba ngu-20% kuya ku-40% wamanje akaliwe.I-current ethize engalayishiwe yenjini ethile ngokuvamile ayimakwa ku-nameplate yemoto noma imanuwali yomkhiqizo.Kodwa abasebenza ngogesi bavame ukudinga ukwazi ukuthi liyini leli nani, futhi basebenzise leli nani ukuze bahlulele ikhwalithi yokukhanda imoto nokuthi ingasetshenziswa yini.
Isilinganiso esilula semoto yamanje engenamthwalo: hlukanisa amandla ngevelu ye-voltage, bese uphindaphinda i-quotient yayo nge-6 ihlukaniswe ngeshumi.
