Ikhwalithi ivame ukuphakanyiswa futhi ivame ukubizwa ngokuthi i-cliché, futhi ngisho nalapho isetshenziswa njenge-buzzword, onjiniyela abaningi bayawulahla lo mbono ngaphambi kokuhlolisisa isimo.Yonke inkampani ifuna ukusebenzisa leli gama, kodwa bangaki abazimisele ukulisebenzisa?Ikhwalithi isimo sengqondo nendlela yokuphila.Ikhwalithi kulula ukuyisho, kodwa kulokhu futhi into engachazwa kuzo zonke izinyathelo zomklamo.Ikhwalithi, okokuqala nokubaluleke kakhulu, kufanele ithathwe ngokungathí sina kusukela phezulu kuya phansi.Imikhiqizo yezimoto efanelekayo idinga ukunakwa: ikhwalithi, ukulethwa, kanye nezindleko (esimeni sokuklama), futhi uma ugxila ezindlekweni, ukwazi kangcono ukunikeza amakhasimende umkhiqizo wekhwalithi ephezulu ngaphandle kobunjiniyela ngokweqile.Lokhu kusho ukuthi kunesixazululo esilula okulula ukusikhiqiza nokuletha.Zonke izingcezu kufanele zihlanganiswe futhi umphakeli wezimoto kufanele aqonde inhloso nenjongo yomklamo womsebenzisi.
Amasistimu okulawula ikhwalithi yangaphakathi yabahlinzeki bezimoto ngokuvamile asebenzisa indlela engu-4.5 sigma, futhi 6 sigma akuyona indlela egculisayo kulokho amakhasimende akutholayo emikhiqizweni yawo.Kuphela ngokulawula okuqinile kwekhwalithi bangaqinisekisa ukuthi umkhiqizo uyadingeka, hhayi nje ngezinjongo zokuklama.Ngalolu hlelo umsebenzisi uthola “injini ehlangabezana ngokungaguquki nangokuthembekile nezidingo ezithile empilweni yemoto”.Lo mgomo ubaluleke kakhulu ekukhiqizweni kwevolumu ephezulu, lapho yonke imigqa yokuhlanganisa ingama kalula ngenxa yokulimala komkhiqizo.Ukuqinisekisa ikhwalithi yama-motor stepper enkampani, agxila ezindaweni ezintathu ezibalulekile, ikhwalithi yengxenye, ikhwalithi yokuklama kanye nekhwalithi yokukhiqiza.
Ukukhethwa kwabahlinzeki-mpahla kudlala indima ebalulekile ekusindeni nasekuthuthukisweni kwemboni yokukhiqiza izimoto kanye namasu okukhiqiza, futhi kuyingxenye ebalulekile yokuphathwa kwe-supply chain.Uma ucubungula ikhwalithi yengxenye, inqubo yokukhiqiza ihlanganisa ama-sub-assemblies amaningi: ama-stators, ama-rotor, ama-shafts, ama-bearings, ama-end cap, ama-winding, ama-lead, izixhumi, nokuningi.Futhi, i-sub-assembly ngayinye ingahlukaniswa ibe izingxenye ezincane ezifana nezintambo, ukwahlukanisa, izindlu kanye nezimpawu, izixhumi, njll. zonke zibe sezingeni eliphezulu ukuze umkhiqizo wokugcina uzodlula.
Kumamotho, ukunemba kwe-dimensional kanye nokugxila kwe-rotor, i-stator nama-end caps kubaluleke kakhulu, ukukhulisa umzila wokugeleza kuwo wonke amazinyo e-stator kanye ne-rotor ngenkathi kunciphisa ukungabaza.Kulokhu, igebe lomoya noma igebe phakathi kwe-rotor ne-stator kumele libe lincane.Uma igebe lomoya lincane, sincane isikhala sephutha lomshini.Lokhu kuzwakala kulula ukukuqonda, kodwa uma ingxenye noma zombili izingxenye zingagxili kahle, okuholela ezikhaleni zomoya ezingalingani kuzoholela ekusebenzeni okungahambisani.Esimweni esibi kakhulu, uma othintana naye kwenzeka, injini iba yize.
I-Rotor inertia ithinta ukusebenza okuphelele kwe-stepper motor. Ama-rotor we-inertia aphansi angaphendula ngokushesha futhi anikeze abasebenzisi isivinini esiphezulu kanye ne-torque ephezulu enamandla. Idizayini ye-end cap efanelekile iqinisekisa umthamo omkhulu wangaphakathi ofakwe ku-rotor enkulu.Ama-caps wokugcina anesibopho sokuqondisa kahle kwe-rotor.Ukungaqondi kahle kungaba nomthelela omkhulu kwikhwalithi yomkhiqizo wokugcina, futhi ukungahambi kahle kwe-rotor kungabangela izikhala zomoya ezingalingani futhi kuholele ekusebenzeni okungalungile.
Lokhu kugxilwa okungahambisani kunxeshezelwa ngokukhuphula ubukhulu begebe lomoya phakathi kwe-rotor ne-stator, ukunciphisa amathuba okuxhumana kwabo.Lokhu kusebenza kuphela ekuqedeni amaphutha.Le ndlela ivimbela kakhulu ukusebenza kwe-stepper motors, futhi uma umehluko omkhulu phakathi kwezingxenye, ukusebenza kuzobe kungahambisani kakhulu.Ngisho nezinguquko ezincane zingaba nemiphumela emikhulu ku-inertia, ukumelana, i-inductance, ukuphuma kwe-torque enamandla kanye ne-resonance (ukudlidliza okungafuneki).Ukwakhiwa kwe-rotor kuyisihluthulelo sokwandisa ukusebenza kwe-motor, i-rotor kumele ibonise indawo yamagnetic eyanele ngenkathi ihlala ilula ngangokunokwenzeka ukuze kuncishiswe inertia ye-rotor.
I-stator ingalungiswa ngokuvumelana nomgomo wokugcina wokuklama: ukunemba okuphezulu, ukushelela noma ukuphuma kwe-torque ephezulu, futhi ukuklama kwezigxobo kunquma ukuthi kungakanani okubambekayo okungangena phakathi kwezigxobo ze-stator.Futhi, inani lezigxobo ngokuvamile li-8, 12 noma 16 lihlotshaniswa nokunemba kanye nokukhishwa kwe-torque yenjini.I-shaft kufanele ibe namandla ngokwanele ukuze imelane nemithwalo ye-torque ephindaphindiwe kanye namandla e-axial ngaphandle kokuguqulwa noma ukuwohloka ngokuhamba kwesikhathi.Ngokunjalo, ama-bearings kumele afane nokusebenza kanye neminyaka yokuphila komkhiqizo wokugcina.Njengengxenye enquma impilo yemoto, ama-bearings avame ukuzwa ukuguga kakhulu.
Ezinye izingxenye ezibucayi zihlanganisa ama-caps wokugcina, abamba ama-bearings endaweni futhi aqinisekise ukuqondana okufanele phakathi kwe-stator ne-rotor.Ama-bearings ngokwawo nawo adinga ukuthi abe sezingeni eliphakeme kakhulu ukugcina nokuqinisekisa impilo ende ye-stepper motor.Isigxobo ngasinye siwuzibuthe kagesi, okwenza kudingeke ukuthi isigxobo ngasinye sijike ngaso sonke isikhathi kusetshenziswa intambo yezinga eliphezulu kakhulu etholakalayo.Ukwehluka kobubanzi bentambo kungabangela izinkinga zokungaguquguquki kwe-pole-winding, okuzoholela ekucacisweni kwetorque okungekuhle, ukuzwakala okwenyukayo noma ukudlidliza, kanye nokungalungiswa kahle komkhiqizo wokugcina.
Ekuphetheni
Indlela yokukhetha abahlinzeki bekhwalithi ephezulu nabawinayo idinga izindlela zokuhlola eziphelele kanye namathuluzi okuhlaziya izibalo athuthukisiwe ukuze kuthuthukiswe amandla okuphatha ukusebenza kwabahlinzeki kanye nokukhuthaza ukuthuthukiswa kwemboni yezimoto.Ukuqinisekisa ikhwalithi yamamotho, injini ngayinye ihlolwa ngaphambi kokuthunyelwa ukuze ihlangabezane nemibandela edingekayo kagesi (ukumelana, inductance, ukuvuza kwamanje), imininingwane ye-torque (ukubamba nokumisa i-torque), imininingwane yomshini (isandiso se-axle yangaphambili nobude bomzimba) nokunye. izici ezikhethekile.
