Njengoba ukusatshalaliswa kokulahlekelwa kwemoto kuhlukahluka ngobukhulu bamandla kanye nenani lezigxobo, ukuze kuncishiswe ukulahlekelwa, kufanele sigxile ekuthatheni izinyathelo zezingxenye eziyinhloko zokulahlekelwa kwamandla ahlukene kanye nezinombolo zezigxobo. Ezinye izindlela zokunciphisa ukulahlekelwa zichazwe kafushane kanje:

1. Khulisa izinto ezisebenzayo ukuze unciphise ukulahleka kokusonta kanye nokulahleka kwensimbi

Ngokuvumelana nesimiso sokufana kwamamotho, lapho umthwalo we-electromagnetic uhlala ungashintshiwe futhi ukulahleka komshini kungacatshangwa, ukulahleka kwemoto kucishe kulingane nekhiyubhu yosayizi womugqa wemoto, futhi amandla okufaka emoto cishe alingana. ngokulingana namandla wesine osayizi womugqa. Kusukela kulokhu, ubudlelwano phakathi kokusebenza kahle kanye nokusetshenziswa okusebenzayo kwempahla kungalinganiselwa. Ukuze uthole indawo enkudlwana ngaphansi kwezimo ezithile zosayizi wokufaka ukuze kubekwe izinto ezisebenza kahle kakhulu ukuze kuthuthukiswe ukusebenza kahle kwenjini, ubukhulu bobubanzi obungaphandle bokubhoboza kwe-stator buba yinto ebalulekile. Ngaphakathi kwebanga elifanayo lesisekelo somshini, amamotho aseMelika anomphumela omkhulu kunamamotho aseYurophu. Ukuze kube lula ukunqanyulwa kokushisa nokunciphisa izinga lokushisa, amamotho aseMelika ngokuvamile asebenzisa ama-stator punching anamadayamitha amakhulu angaphandle, kuyilapho ama-motor ase-Europe evamise ukusebenzisa ama-stator punching ane-diameter emincane yangaphandle ngenxa yesidingo sokuphuma kwesakhiwo njengama-motor-proof-proof kanye nokunciphisa amandla. inani lethusi elisetshenziswa ekugcineni kanye nezindleko zokukhiqiza.

2. Sebenzisa izinto ezingcono kazibuthe futhi inqubo izinyathelo ukunciphisa ukulahleka kwensimbi

Izakhiwo kazibuthe (ukungena kazibuthe kanye nokulahlekelwa kwensimbi yeyunithi) yezinto eziyinhloko zinethonya elikhulu ekusebenzeni kahle nokunye ukusebenza kwemoto. Ngesikhathi esifanayo, izindleko zezinto eziyinhloko ziyingxenye eyinhloko yezindleko zemoto. Ngakho-ke, ukukhethwa kwezinto ezifanele kazibuthe kuyisihluthulelo sokuklama nokukhiqiza ama-motor asebenza kahle kakhulu. Kumamotho anamandla aphezulu, ukulahleka kwensimbi kubala ingxenye enkulu yokulahlekelwa okuphelele. Ngakho-ke, ukunciphisa inani lokulahlekelwa kweyunithi yezinto eziyinhloko kuzosiza ukunciphisa ukulahlekelwa kwensimbi ye-motor. Ngenxa yokwakheka nokukhiqizwa kwenjini, ukulahleka kwensimbi kwenjini kulidlula kakhulu inani elibalwe ngokwenani leyunithi yokulahlekelwa kwensimbi elinikezwa isigayo sensimbi. Ngakho-ke, inani lokulahlekelwa kwensimbi yeyunithi ngokuvamile likhuphuka izikhathi ezingu-1.5 ~ 2 ngesikhathi sokuklama ukuze kucatshangelwe ukwanda kokulahlekelwa kwensimbi.

Isizathu esiyinhloko sokwanda kokulahlekelwa kwensimbi ukuthi inani lokulahlekelwa kwensimbi yeyunithi yesigayo sensimbi litholakala ngokuhlola isampula lempahla ye-strip ngokwendlela ye-Epstein square circle. Kodwa-ke, impahla ingaphansi kokucindezeleka okukhulu ngemva kokubhoboza, ukugunda kanye ne-laminating, futhi ukulahlekelwa kuzokwanda. Ngaphezu kwalokho, ukuba khona kwe-slot yezinyo kubangela izikhala zomoya, okuholela ekulahlekelweni kwe-no-load ebusweni bomgogodla obangelwa insimu yamagnetic yezinyo. Lokhu kuzoholela ekwenyukeni okukhulu kokulahleka kwensimbi yemoto ngemuva kokwakhiwa. Ngakho-ke, ngaphezu kokukhetha izinto zamagnetic ezinokulahlekelwa kwensimbi ephansi, kuyadingeka ukulawula ukucindezela kwe-lamination futhi uthathe izinyathelo ezidingekayo zenqubo yokunciphisa ukulahlekelwa kwensimbi. Uma kubhekwa amanani kanye nezici zenqubo, amashidi ensimbi ye-silicon esezingeni eliphezulu namashidi ensimbi ye-silicon azacile kuno-0.5mm awasetshenziswa kakhulu ekukhiqizeni amamotho asebenza kahle kakhulu. Ngokuvamile kusetshenziswa amashidi ensimbi angenakhabhoni ephansi ye-silicon noma amashidi ensimbi ye-silicon ebandayo egoqelwe ephansi. Abanye abakhiqizi bamamotho amancane aseYurophu basebenzise amashidi ensimbi kagesi angenayo i-silicon enenani lokulahlekelwa kwensimbi engu-6.5w/kg. Eminyakeni yakamuva, izigayo zensimbi zethule amashidi ensimbi kagesi e-Polycor420 anokulahleka kweyunithi okumaphakathi okungu-4.0w/kg, okungaphansi ngisho kunamanye amashidi ensimbi ane-silicon ephansi. Izinto ezisetshenziswayo futhi zinokungena kazibuthe okuphezulu.

Eminyakeni yamuva nje, iJapan iye yakha ishidi lensimbi eligoqelwe nge-silicon ephansi elinezinga elingu-50RMA350, elinenani elincane le-aluminium nezinsimbi zomhlaba ezingavamile ezingezwe ekubunjweni kwalo, ngaleyo ndlela ligcine amandla kazibuthe aphezulu ngenkathi kunciphisa ukulahlekelwa, futhi inani lokulahlekelwa kwensimbi ngu-3.12w/kg. Lokhu kungenzeka kunikeze isisekelo esihle sezinto ezibonakalayo sokukhiqizwa nokukhuthazwa kwamamotho asebenza kahle kakhulu.

3. Yehlisa usayizi wefeni ukuze unciphise ukulahlekelwa komoya

Kumandla amakhulu ama-2-pole kanye nama-4-pole motors, ukungqubuzana komoya kubangela ingxenye enkulu. Isibonelo, ukungqubuzana komoya kwenjini engu-90kW 2-pole motor kungafinyelela cishe ku-30% wengqikithi yokulahlekelwa. Ukungqubuzana komoya ikakhulukazi kwakhiwe amandla asetshenziswa ifeni. Njengoba ukulahlekelwa ukushisa kwamamotho asebenza kahle kakhulu ngokuvamile kuphansi, umthamo womoya opholile ungancishiswa, futhi ngaleyo ndlela amandla okungenisa umoya nawo angancishiswa. Amandla okungenisa umoya acishe alingane namandla we-4 kuya ku-5 wobubanzi befeni. Ngakho-ke, uma izinga lokushisa livuma, ukunciphisa usayizi wefeni kunganciphisa ngempumelelo ukungqubuzana komoya. Ngaphezu kwalokho, ukuklama okunengqondo kwesakhiwo sokungenisa umoya nakho kubalulekile ekuthuthukiseni ukusebenza kahle kokukhipha umoya kanye nokunciphisa ukungqubuzana komoya. Ukuhlola kubonise ukuthi ukungqubuzana komoya kwengxenye enamandla angu-2-pole yemoto esebenza kahle kakhulu kungancishiswa cishe ngo-30% uma kuqhathaniswa namamotho avamile. Njengoba ukulahlekelwa komoya kunciphisa kakhulu futhi akudingi izindleko ezengeziwe, ukushintsha umklamo wabalandeli ngokuvamile kungenye yezinyathelo eziyinhloko ezithathwe kule ngxenye yamamotho asebenza kahle kakhulu.

4. Nciphisa ukulahlekelwa okunhlanhlathayo ngokusebenzisa izinyathelo zokuklama nezinqubo

Ukulahlekelwa okulahlekile kwama-asynchronous motors kubangelwa ikakhulukazi ukulahlekelwa kwe-high-frequency ku-stator kanye ne-rotor cores kanye nama-windings okubangelwa ukuhleleka okuphezulu kwe-harmonics yamagnetic field. Ukuze kuncishiswe ukulahleka komthwalo, i-amplitude ye-harmonic yesigaba ngasinye ingancishiswa ngokusebenzisa ama-winding e-sinusoidal axhumeke kuchungechunge lwe-Y-Δ noma amanye ama-winding-harmonic aphansi, ngaleyo ndlela kuncishiswe ukulahlekelwa okulahlekile. Ukuhlolwa kubonise ukuthi ukusetshenziswa kwe-sinusoidal windings kunganciphisa ukulahlekelwa okulahlekile ngaphezu kuka-30% ngokwesilinganiso.

5. Thuthukisa inqubo ye-die-casting ukunciphisa ukulahlekelwa kwe-rotor

Ngokulawula ukucindezela, izinga lokushisa kanye nendlela yokukhipha igesi ngesikhathi senqubo yokukhipha i-aluminium ye-rotor, igesi emigodini ye-rotor ingancishiswa, ngaleyo ndlela ithuthukise ukuqhutshwa kwe-conductivity futhi inciphise ukusetshenziswa kwe-aluminium ye-rotor. Eminyakeni yamuva nje, i-United States ithuthukise ngempumelelo imishini yokuphonsa i-copper rotor kanye nezinqubo ezihambisanayo, futhi njengamanje yenza ukukhiqizwa kwesivivinyo esincane. Izibalo zibonisa ukuthi uma ama-rotor ethusi athatha indawo ye-aluminium rotor, ukulahlekelwa kwe-rotor kungancishiswa cishe ngama-38%.

6. Sebenzisa idizayini yokuthuthukisa ikhompuyutha ukuze unciphise ukulahlekelwa futhi uthuthukise ukusebenza kahle

Ngokungeziwe ekwandiseni izinto zokwakha, ukuthuthukisa ukusebenza kwempahla kanye nezinqubo ezithuthukisayo, idizayini yokwenza kahle ikhompuyutha isetshenziselwa ukunquma ngokunengqondo amapharamitha ahlukahlukene ngaphansi kwemikhawulo yezindleko, ukusebenza, njll., ukuze kutholwe ukuthuthukiswa okukhulu okungenzeka ekusebenzeni kahle. Ukusetshenziswa komklamo wokwenza kahle kunganciphisa kakhulu isikhathi sokuklanywa kwezimoto futhi kuthuthukise ikhwalithi yomklamo wemoto.
