Yenziwa njani amandla e-axial yenqanaba lesithathu le-asynchronous motor? Nokuba ngabai-high-voltage okanye i-low-voltage motor yombane, iingxaki zokufuduswa kwe-shaft okanye amandla e-axial abangela ukuba ubushushu obuthwele buphakame bubikwa ngamaxesha athile. Eyona meko ilungileyo yokusebenza kwemoto kukuba akukho mandla kwicala le-axial kwaye unxibelelwano olufanelekileyo phakathi kwemoto kunye nomthwalo luqinisekisiwe; eneneni, ezahlukeneyo iimotor ezikwinqanaba lesithathu ezine-asynchronous zinamandla amakhulu okanye angaphantsi kwe-axial.
Kwi Inqanaba lesithathu le-asynchronous motor, xa i-stator winding iqhagamshelwe kunikezelo lwamandla, intsimi yamagnetic ejikelezayo iveliswa, ukwenzela ukuba i-current induced iveliswe kwi-rotor ngenxa yokungeniswa kwe-electromagnetic, kwaye i-rotor yenziwe ngemagnethi kwaye ivelise umtsalane ojikelezayo we-electromagnetic.
Emva kokuzonwabisa, i I-motor induction synchronous ijikeleza ngesantya esihambelanayo, kwaye ukujikeleza kwesigaba sesithathu se-asynchronous motor kuvelisa i-slip. Umxhuzulane wommandla wemagnethi ojikelezayo wemoto uveliswa ngokusekwe kwezona mpawu zimfutshane zemigca yemagnethi yamandla. Amandla ombane we-electromagnetic enza ukuba imoto iqhube kumgca we-electromagnetic center, oko kukuthi, amandla ombane we-motor stator kunye ne-rotor alungelelaniswa enye kwenye kwicala le-radial, kwaye akukho mandla axial magnetic awenziwayo. Nangona kunjalo, ekusebenzeni okwenyani, amandla e-axial aya kuveliswa ngenxa yezi zinto zilandelayo.
Ziziphi izizathu ze-axial force ye-Sima motor?
-Amandla e-axial aveliswa ngumoya wokupholisa xa i-motor rotor fan isebenza ngaphandle komthwalo.
-Ngenxa yezinto ezinje ngenkqubo yokuvelisa kunye nempazamo yendibano yenqanaba lesithathu le-asynchronous motor, umgca weziko lomatshini kunye nomgca ophakathi we-electromagnetic wemoto uyaphambukiswa, kwaye i-stator kunye ne-rotor iya kuvelisa amandla e-axial.
-Ukuze kuncitshiswe impembelelo ye-harmonics yezinyo, i-stator okanye i-rotor ithatha isakhiwo se-slot e-skewed. Xa umthwalo uqhuba, amandla e-electromagnetic anyanzela i-rotor ukuba igobe ukuya kwelinye icala ukuvelisa amandla e-axial.
-Umgca we-electromagnetic center of the three-phase-asynchronous motor ngumgca wereferensi yokudibanisa phakathi kwe-motor shaft kunye nokudibanisa izixhobo zoomatshini. Nangona kunjalo, kuba akukho phawu lomgca we-electromagnetic center kuyilo lwemoto kunye nokuveliswa, imilinganiselo yokulinganisa imizobo yofakelo kumaxwebhu akhaphayo isekwe kuyilo lweziko lomatshini xa kufakwa imoto kunye nokudibanisa.
Ngale ndlela, ekusebenzeni kwangempela kwe-injini, ngenxa yokungahambi kakuhle komgca weziko lomatshini kunye nomgca weziko le-electromagnetic, ezi meko zilandelayo ziya kwenzeka ngokuqinisekileyo: H Ngenxa yempazamo yokufakela i-motor kunye nokudibanisa kunye ne-axial force eyenziwe. Isalathiso samandla e-axial kukutyhala okanye ukutsala amandla e-axial kwisixhobo somatshini esiqhutywayo, okukhokelela kumonakalo kwimoto kunye neebheringi zezixhobo zoomatshini eziqhutywayo okanye umatshini wonke. Kwi-brushless excitation motors synchronous motors ezinokhuseleko oluphezulu, izinto zikhulu, ngoko ke ngokombono wenkqubo yokuvelisa kunye nokucubungula, umgangatho wesitampu uphuculwe kwaye i-stamping burrs iyancitshiswa; uqeqesho, ukuqinisekisa ubude be-stator kunye ne-rotor cores, ukuphepha ukufakwa kwabantu kunye neempazamo zendibano, ezifuna abasebenzi bezobugcisa benkampani ukuba babe nomgangatho ophezulu wobugcisa kunye nezakhono ezifanelekileyo zokuhlanganisa, yinkqubo yesiqinisekiso sokunciphisa amandla e-axial.
Ukongeza, umyili kufuneka aqhelane nenkqubo yokwenziwa kwemveliso kunye nenkqubo yokuhlanganisa imveliso, kunye nobungakanani kunye nesalathiso samandla e-axial abangelwa zizinto ezingokwemvelo ezifana noyilo lwesakhiwo, ukujikeleza kwemoto, indawo yefeni kunye nomkhombandlela we-chute kufuneka ziqwalaselwe kuyilo lolwakhiwo ukuze bakwazi ukukhawulelana okanye banciphise. Kwangaxeshanye, amagcisa endibano yemveliso kufuneka athathe inxaxheba kumzamo wokuqala wokuqalisa emva kokuhlanganiswa kwemveliso. Ngexesha lokuqhutywa kovavanyo, okona kubaluleke kakhulu, amagcisa ovavanyo kufuneka afune ngokuchanekileyo ukudibanisa kumaxwebhu obugcisa ngokusekwe kweyona datha yokufuduswa komgca ophakathi wenqanaba lesithathu lemoto ye-asynchronous kunye neziko lombane lombane elivavanyiweyo kuvavanyo lokungathwali kunye nomthwalo ngexesha lovavanyo lwendibano yovavanyo lweprototype. Emva koko, i-motor ilungelelanisa ixabiso lokufuduka kwaye iguqule isalathiso sokutshintsha kwindawo ye-rotor ngexesha lenkqubo.
