1. I-gap yomoya phakathi kwe-stator kunye ne-rotor ye-motor incinci kakhulu, ekulula ukubangela ukungqubana phakathi kwe-stator kunye ne-rotor.
Kwiimotor eziphakathi nezincinci, isithuba somoya siqhele ukuba yi-0.2mm ukuya kwi-1.5mm.Xa i-gap yomoya inkulu, i-excitation current iyadingeka ukuba ibe nkulu, ngaloo ndlela ichaphazela amandla ombane wemoto;ukuba i-gap yomoya incinci kakhulu, i-rotor inokuxubha okanye idibanise.Ngokubanzi, ngenxa yokunganyamezeli okunzulu kokuthwala kunye nokunxiba kunye nokuguqulwa komngxuma wangaphakathi wesigqubuthelo sokugqibela, i-axes ezahlukeneyo zesiseko somatshini, isigqubuthelo sokugqibela kunye nerotor zibangela ukutshayela, oku kunokubangela lula. Injini ukutshisa okanye ukutshisa.Ukuba ukuthwala kufunyenwe ukuba kugugile, kufuneka kutshintshwe ngexesha, kwaye isigqubuthelo sokugqibela kufuneka sitshintshwe okanye sixutywe.Indlela elula yonyango kukufaka umkhono kwi-cover cover.
2. Ukungcangcazela okungaqhelekanga okanye ingxolo yemoto inokubangela lula ukufudumeza kwemoto
Le meko yeyokungcangcazela okubangelwa yimoto ngokwayo, uninzi lwazo lubangelwa kukungalungelelani kakuhle kwe-rotor, kunye neebheringi ezihlwempuzekileyo, ukugoba kweshaft ejikelezayo, amaziko ahlukeneyo e-axial ye-cover cover, isiseko somatshini kunye ne-rotor. , i-fasteners ekhululekile okanye isiseko esingalinganiyo sofakelo lwemoto, kwaye ukufakela akukho ndawo.Isenokubangelwa kukuphela komatshini, okufuneka ingabandakanywa ngokweemeko ezithile.
3. Ukuthwala akusebenzi kakuhle, okuya kubangela ukuba i-motor ifudumale
Ukuba ukuthwala kusebenza ngokuqhelekileyo kunokugwetywa ngokuva kunye namava obushushu.Sebenzisa isandla okanye ithemometha ukubona isiphelo sokuthwala ukugqiba ukuba ubushushu bayo buphakathi koluhlu oluqhelekileyo;ungasebenzisa kwakhona intonga yokumamela (intonga yobhedu) ukubamba ibhokisi yokuthwala.Ukuba uva isandi sempembelelo, oko kuthetha ukuba ibhola enye okanye ezininzi zinokutyunyuzwa.Isandi se-hising, oko kuthetha ukuba i-oyile yokuthambisa ye-bearing ayonelanga, kwaye imoto kufuneka itshintshwe ngegrisi rhoqo kwiiyure ezingama-3,000 ukuya kwezingama-5,000 zokusebenza.
4. I-voltage yonikezelo lwamandla iphezulu kakhulu, i-excitation current iyanda, kwaye i-motor iya kudlula
Iivoltheji ezigqithisileyo zinokubeka emngciphekweni ukufakwa kwemoto, kuyibeka emngciphekweni wokuqhekeka.Xa amandla ombane aphantsi kakhulu, itorque ye-electromagnetic iya kuncitshiswa.Ukuba i-torque yomthwalo ayincitshiswanga kwaye isantya se-rotor siphantsi kakhulu, ukwanda komlinganiselo we-slip kuya kubangela ukuba i-motor ilayishe kwaye ifudumale, kwaye ukugqithiswa kwexesha elide kuya kuchaphazela ubomi bemoto.Xa i-voltage yesigaba sesithathu i-asymmetric, oko kukuthi, xa i-voltage yesigaba esinye iphezulu okanye iphantsi, i-current yesigaba esithile iya kuba nkulu kakhulu, i-motor iya kufudumala, kwaye kwangaxeshanye, i-torque iya kuba kuncitshiswe, kwaye isandi esithi "humming" siya kukhutshwa, esiya konakalisa ukujikeleza ixesha elide.
Ngamafutshane, kungakhathaliseki ukuba i-voltage iphezulu kakhulu, iphantsi kakhulu okanye i-voltage i-asymmetrical, yangoku iya kwanda, kwaye i-motor iya kutshisa kwaye yonakalise i-motor.Ngoko ke, ngokomgangatho wesizwe, ukutshintshwa kwamandla ombane ombane akufanele kudlule i-± 5% yexabiso elilinganisiweyo, kwaye amandla okukhutshwa kweemoto anokugcina ixabiso elilinganisiweyo.I-voltage yombane we-motor ayivumelekanga ukuba idlule ± 10% yexabiso elilinganisiweyo, kwaye umahluko phakathi kwezigaba ezintathu zombane wombane akufanele udlule i-± 5% yexabiso elilinganisiweyo.
5. I-winding short circuit, i-turn-to-turn short circuit, i-phase-to-phase short circuit kunye ne-winding open circuit.
Emva kokuba i-insulation phakathi kweengcingo ezimbini ezikufutshane kwi-winding yonakalisiwe, abaqhubi ababini bayangqubana, okubizwa ngokuba yi-winding short circuit.Isekethe emfutshane ejikajikayo eyenzeka kwindawo enye ibizwa ngokuba yi-turn-to-turn short circuit.Isekethe emfutshane ejikajikayo eyenzeka phakathi kwamajiko-jiko amabini ibizwa ngokuba yi-interphase short circuit.Kungakhathaliseki ukuba yeyiphi na, iya kwandisa i-current yesigaba esinye okanye izigaba ezibini, ibangele ukufudumeza kwendawo, kwaye yonakalise i-motor ngenxa yokuguga kwe-insulation.Ukuvunguza kwesekethe evulekileyo kubhekiselele kwimpazamo ebangelwa kukuqhekeka okanye ukutshiswa kwe-stator okanye i-rotor winding ye-motor.Nokuba i-wind-circuited imfutshane okanye ivulekile, inokubangela ukuba i-motor ifudumale okanye itshise.Ngoko ke, kufuneka iyekwe ngoko nangoko emva kokuba oku kwenzeke.
6. Izinto zivuza ngaphakathi kwi-motor, enciphisa ukugquma kwe-motor, ngaloo ndlela inciphisa ukunyuka kobushushu obuvumelekileyo be-motor.
Izinto eziqinileyo okanye uthuli olungena kwi-motor ukusuka kwibhokisi ye-junction luya kufikelela kwisithuba somoya phakathi kwe-stator kunye ne-rotor ye-motor, ebangela ukuba i-motor itshayelwe, ide i-insulation ye-motor winding igugile, ibangele ukuba i-motor yonakaliswe okanye ikhutshwe. .Ukuba ulwelo kunye negesi ephakathi ziyavuza kwi-motor, iya kubangela ngokuthe ngqo ukugquma kwemoto kwehla kwaye ihambe.
Ulwelo ngokubanzi kunye nokuvuza kwerhasi kunezibonakaliso zilandelayo:
(1) Ukuvuza kwezikhongozeli ezahlukeneyo kunye nemibhobho yokuhambisa, ukuvuza kwezitywina zomzimba wempompo, izixhobo zokugungxula kunye nomhlaba, njl.
(2) Emva kokuvuza kwe-oyile yoomatshini, ingena kwi-motor ukusuka kwisithuba sebhokisi yokuthwala yangaphambili.
(3) Izitywina zeoyile ezifana nesinciphisi esiqhagamshelwe kwinjini ziyanxitywa, kwaye ioyile yokuthambisa esebenza ngoomatshini ingena ecaleni kweshafti yemoto.Emva kokuqokelela ngaphakathi kwi-motor, ipeyinti ye-motor insulating iyachithwa, ukwenzela ukuba ukusebenza kwe-insulation ye-motor kuncitshiswe ngokuthe ngcembe.
7. Phantse isiqingatha sokutshiswa kwemoto kubangelwa kukungabikho kwesigaba sokusebenza kwemoto
Ukungabikho kwesigaba kudla ngokubangela ukuba i-motor ingaphumeleli ukubaleka, okanye ukujikeleza ngokukhawuleza emva kokuqala, okanye ukuvelisa isandi esithi "humming" xa amandla engajikelezi kwaye ukwanda kwangoku.Ukuba umthwalo kwi-shaft awutshintshi, i-motor ilayishwe kakhulu kwaye i-stator yangoku iya kuba ngamaxesha angama-2 ixabiso elilinganisiweyo okanye ngaphezulu.Ngexesha elifutshane, i-motor iya kutshisa okanye iphele.bangela ilahleko yesigaba.
Ezona zizathu ziphambili zezi zilandelayo:
(1) Ukusilela kombane kwinqanaba elinye okubangelwe kukusilela kombane wesinye isixhobo kwintambo yombane kuya kubangela ukuba ezinye izixhobo zezigaba ezithathu eziqhagamshelwe kuntambo zisebenze ngaphandle kwesigaba.
(2) Esinye isigaba se-breaker circuit okanye i-contactor iphelile ngenxa yokutshiswa kwe-voltage ye-bias okanye uqhagamshelwano olubi.
(3) Ilahleko yeSigaba ngenxa yokuguga, ukuguga, njl njl kumgca ongenayo wemoto.
(4) Isigaba esinye somoya we-motor yisekethe evulekileyo, okanye isiqhagamshelo sesigaba esisodwa kwibhokisi ye-junction sikhululekile.
8. Okunye ukusilela kombane okungengoomatshini kubangela
Ukunyuka kobushushu bemoto okubangelwa zezinye iziphene zombane ezingezizo ezomatshini nazo zinokukhokelela ekungaphumeleli kwemoto kwiimeko ezinzima.Ukuba ubushushu be-ambient buphezulu, i-motor ayinayo ifeni, ifeni ayiphelelanga, okanye isigqubuthelo sefeni silahlekile.Kule meko, ukupholisa ngenkani kufuneka kuqinisekiswe ukuqinisekisa ukungena komoya okanye ukutshintshwa kwee-fan blades, ngaphandle koko ukusebenza okuqhelekileyo kwemoto akunakuqinisekiswa.
Ukushwankathela, ukuze usebenzise indlela echanekileyo yokujongana neziphene zeemoto, kuyimfuneko ukuba uqhelane neempawu kunye nezizathu zeempazamo eziqhelekileyo zeemoto, ubambe izinto eziphambili, kwaye uqhube ukuhlolwa kunye nokugcinwa rhoqo.Ngale ndlela, sinokunqanda ukujikwa, ukonga ixesha, ukulungisa ingxaki ngokukhawuleza, kwaye sigcine imoto ikwimeko eqhelekileyo yokusebenza.Ukuze kuqinisekiswe imveliso eqhelekileyo yocweyo.
