Umgangatho uhlala uthathwa kwaye uhlala ubizwa ngokuba yi-cliché, kwaye nangona isetyenziswe njenge-buzzword, iinjineli ezininzi ziphosa ingcamango ngaphandle kwendlela ngaphambi kokuba ihlolisise imeko.Yonke inkampani ifuna ukusebenzisa eli gama, kodwa bangaphi abazimisele ukulisebenzisa?Umgangatho sisimo sengqondo kunye nendlela yokuphila.Umgangatho kulula ukuthetha, kodwa kule meko kwakhona into enokuthi ichazwe kuwo onke amanyathelo oyilo.Umgangatho, okokuqala nokuphambili, kufuneka uthathwe ngokungathí sina ukusuka phezulu ukuya phezulu.Iimveliso zeemoto ezifanelekileyo zifuna ukuhoywa: umgangatho, ukuhanjiswa, kunye neendleko (kwimeko yoyilo), kwaye ukuba ugxininise kwiindleko, uyakwazi ukubonelela abathengi ngeyona mveliso ikumgangatho ophezulu ngaphandle kobunjineli obugqithisileyo.Oku kuthetha ukuba kukho isisombululo esilula ekulula ukusivelisa nokuhambisa.Zonke iziqwenga kufuneka zidityaniswe kwaye umthengisi wemoto kufuneka aqonde injongo kunye nenjongo yoyilo lomsebenzisi.
Iinkqubo zokulawula umgangatho wangaphakathi wababoneleli ngeemoto ikakhulu zisebenzisa indlela ye-4.5 sigma, kwaye i-6 sigma ayikho indlela eyanelisayo kwizinto abathengi abahlangabezana nazo kwiimveliso zabo.Kuphela ngolawulo olungqongqo lwekhwalithi abanokuqinisekisa ukuba imveliso iyadingeka, kungekhona nje ngeenjongo zokuyila.Ngale nkqubo umsebenzisi ufumana "injini ethe gqolo nangokuthembekileyo ihlangabezana neemfuno ezithile kubomi bemoto".Le njongo ibaluleke kakhulu kwimveliso ephezulu, apho yonke imigca yendibano inokuthi ifike ngokulula ngenxa yeziphene zemveliso.Ukuqinisekisa umgangatho weenjini ze-stepper zenkampani, zigxininisa kwiindawo ezintathu eziphambili, umgangatho wecandelo, umgangatho woyilo kunye nomgangatho wokuvelisa.
Ukukhethwa kwababoneleli-mpahla kudlala indima ebalulekileyo ekusindeni nasekuphuhliseni ishishini lokwenziwa kweemoto kunye neqhinga lokuvelisa, kwaye liyinxalenye ebalulekileyo yolawulo lwekhonkco lokubonelela.Xa uqwalasela umgangatho wecandelo, inkqubo yokuvelisa ibandakanya ii-sub-assemblies ezininzi: i-stators, i-rotors, i-shafts, i-bearings, i-end caps, i-windings, i-lead, i-connectors, kunye nokunye.Kwakhona, i-sub-assembly nganye inokwahlulwa ibe yi-sub-assembly ezifana neengcingo, ukugquma, izindlu kunye netywina, izihlanganisi, njl. zonke zibe zowona mgangatho uphezulu ukuze imveliso yokugqibela idlule.
Kwiimoto, ukuchaneka kwe-dimensional kunye nokugxila kwe-rotor, i-stator kunye ne-end caps zibaluleke kakhulu, ukwandisa umzila we-flux kwi-stator kunye namazinyo e-rotor ngelixa unciphisa ukungafuni.Kule nto, i-gap yomoya okanye i-gap phakathi kwe-rotor kunye ne-stator kufuneka ibe yincinci.Okukhona umncinci umsantsa womoya, kokukhona usiba mncinci indawo yempazamo yomatshini.Oku kuvakala kulula ukuyiqonda, kodwa ukuba elinye okanye omabini amacandelo akagxininisi kakuhle, okukhokelela kwizithuba zomoya ezingalinganiyo kuya kubangela ukusebenza okungahambelaniyo.Kwimeko embi kakhulu, ukuba uqhagamshelwano lwenzeka, i-motor iba yinto engenamsebenzi.
Inertia ye-Rotor ichaphazela ukusebenza ngokubanzi kwe-motor stepper.I-inertia rotors ephantsi inokuphendula ngokukhawuleza kwaye ibonelele abasebenzisi ngesantya esiphezulu kunye ne-torque ephezulu.Uyilo oluchanekileyo lwe-cap end cap luqinisekisa umthamo wangaphakathi ophezulu ofakwe kwi-rotor enkulu.Ii-caps zokuphela zijongene nokulungelelaniswa okuchanekileyo kwe-rotor.Ukungalungi kakuhle kunokuba nempembelelo enkulu kumgangatho wemveliso yokugqibela, kwaye ukungahambi kakuhle kwe-rotor kunokubangela izithuba zomoya ezingalinganiyo kwaye kukhokelela ekusebenzeni kakubi.
Oku kugxininiswa okungahambelaniyo kuhlawulelwa ngokunyusa ubungakanani besithuba somoya phakathi kwe-rotor kunye ne-stator, ukunciphisa amathuba okuqhagamshelana kwabo.Oku kusebenza kuphela ekupheliseni iimpazamo.Le ndlela ithintela kakhulu ukusebenza kwee-motor stepper, kwaye ukuhluka okukhulu phakathi kwamalungu, kokukhona kuya kuhambelana nokusebenza.Kwanotshintsho oluncinci lunokuba neziphumo ezinkulu kwi-inertia, ukuxhathisa, i-inductance, i-torque eguqukayo kunye ne-resonance (ukungcangcazela okungafunekiyo).Uyilo lwe-rotor lungundoqo ekwandiseni ukusebenza kwe-motor, i-rotor kufuneka ibonise indawo eyaneleyo yamagnetic ngelixa ihlala ilula ngokusemandleni ukunciphisa inertia ye-rotor.
I-stator inokulungiswa ngokwenjongo yokuphela koyilo: ukuchaneka okuphezulu, ukugudiswa okanye ukuphuma kwe-torque ephezulu, kunye noyilo lwezibonda lumisela ukuba zininzi kangakanani izinto ezijikelezayo ezinokungena phakathi kwezibonda ze-stator.Kwakhona, inani leepali ngokuqhelekileyo i-8, i-12 okanye i-16 ihambelana nokuchaneka kunye nokuphuma kwe-torque ye-motor.I-shaft kufuneka yomelele ngokwaneleyo ukuze imelane nemithwalo ye-torque ephindaphindiweyo kunye ne-axial forces ngaphandle kokuguqulwa okanye ukuthotywa kwexesha.Ngokunjalo, iibheringi kufuneka zihambelane nokusebenza kunye nexesha elilindelekileyo lobomi bemveliso yokugqibela.Njengenxalenye emisela ubomi bemoto, iibheringi zihlala zifumana eyona nto inxibayo.
Amanye amacandelo abalulekileyo abandakanya ii-caps zokugqibela, ezibamba iibheringi kunye nokuqinisekisa ukulungelelaniswa okufanelekileyo phakathi kwe-stator kunye ne-rotor.Iibheringi ngokwazo nazo kufuneka zibe zowona mgangatho uphezulu ukugcina kunye nokuqinisekisa ubomi obude bemoto ye-stepper.Ipali nganye inguzibuthe we-electromagnetic, nto leyo efuna ukujijwa ngendlela efanayo kwipali nganye kusetyenziswa olona cingo luphezulu lukhoyo.Ukwahluka kwidayamitha yocingo kunokubangela imiba yokungaguquguquki kwepali nganye, nto leyo eya kubangela ukucaciswa kwetorque embi, ukonyuka kweresonance okanye ukungcangcazela, kunye nesisombululo esibi kwimveliso yokugqibela.
ukuququmbela
Indlela yokukhetha ababoneleli abakumgangatho ophezulu kunye nokuphumelela-ukuphumelela kufuna iindlela zovavanyo olubanzi kunye nezixhobo zokuhlalutya izibalo eziphuculweyo zokuphucula amandla okulawula ukusebenza komthengisi kunye nokukhuthaza uphuhliso loshishino lweemoto.Ukuqinisekisa umgangatho weenjini, i-motor nganye iyavavanywa phambi kokuthunyelwa ukuze ihlangabezane neenkcukacha zombane ezifunekayo (ukuchasa, inductance, ukuvuza kwangoku), iinkcukacha zetorque (ukubamba kunye nokumisa i-torque), iinkcukacha zoomatshini (ukwandiswa kwe-axle yangaphambili kunye nobude bomzimba) kunye nokunye. Imiboniso eyodwa.
