Ngesikhathi sokusebenza kwenjini, ukuqapha kwesikhathi sangempela kwamapharamitha njengamanje, isivinini sokujikeleza, kanye nendawo ehlobene yeshaft ezungezayo endaweni ejikelezayo, ukunquma isimo somzimba wemoto kanye nezinto ezisetshenziswayo, kanye nokulawula okuqhubekayo. isimo sokusebenza kwemoto kanye nemishini ngesikhathi sangempela, ukuze uthole imisebenzi eminingi ethile efana ne-servo kanye nokulawulwa kwesivinini.Izici.Lapha, ukusebenzisa i-encoder njengengxenye yokulinganisa yangaphambili akugcini nje ngokwenza lula kakhulu uhlelo lokulinganisa, kodwa futhi kunembile, kuthembekile futhi kunamandla.

I-encoder iyinzwa ejikelezayo eguqula indawo kanye nokugudluzwa kwezingxenye ezijikelezayo zibe uchungechunge lwamasignali we-digital pulse.Lezi zibonakaliso ze-pulse ziqoqwa futhi zicutshungulwe uhlelo lokulawula, futhi uchungechunge lweziyalezo lukhishwa ukulungisa nokuguqula isimo sokusebenza semishini.Uma isishumeki sihlanganiswe ne-gear rack noma isikulufu, singasetshenziswa futhi ukukala indawo kanye nokugudluzwa kwezingxenye ezihambayo.

Izifaki khodi zisetshenziswa ezinhlelweni zempendulo yesignali yokuphuma kwezimoto, ukulinganisa kanye nemishini yokulawula.Isishumeki sakhiwe izingxenye ezimbili: i-optical code disc kanye nomamukeli.Imingcele ye-optical variable ekhiqizwa ukujikeleza kwe-optical code disc iguqulwa ibe imingcele kagesi ehambisanayo, futhi amasignali ashayela amadivayisi kagesi aphuma nge-preamplifier kanye nesistimu yokucubungula isignali ku-inverter..

Ngokuvamile, isishumeki esijikelezayo singakwazi ukubuyisela isignali yesivinini kuphela, eqhathaniswa nenani elimisiwe futhi ibuyiselwe kuyunithi yokukhipha inverter ukulungisa isivinini semoto.

Ngokomgomo wokutholwa, isishumeki singahlukaniswa sibe yi-optical, magnetic, inductive kanye ne-capacitive.Ngokwendlela yayo yesikali kanye nefomu lokukhipha isignali, ingahlukaniswa ngezinhlobo ezintathu: okukhulayo, okuphelele kanye ne-hybrid.

Isifaki khodi esikhuphukayo, indawo yaso inqunywa inani lama-pulses abalwe ukusuka ku-zero mark;iguqula ukugudluzwa kube isignali kagesi yezikhathi ezithile, bese iguqula isignali kagesi ibe ishayela lokubala, futhi inani lama-pulses lisetshenziselwa ukumela usayizi wokuthutha;absolute Indawo yohlobo lokufaka ikhodi inqunywa ukufundwa kwekhodi yokuphumayo.Ukufundwa kwekhodi yokuphuma kwendawo ngayinye ngaphakathi kwendingiliza kuhlukile, futhi ukuxhumana okukodwa kuya koyedwa okunendawo yangempela ngeke kulahleke lapho amandla enqanyulwa.Ngakho-ke, lapho isishumeki esikhuphukayo sivaliwe futhi sivulwa futhi, ukufundwa kwendawo okwamanje;indawo ngayinye yesishumeki sekhodi esiphelele sihambisana nekhodi ethile yedijithali, ngakho-ke inani layo elibonisiwe lihlobene kuphela nendawo yokuqala nesiphetho yesilinganiso, kuyilapho Ayihlangene nenqubo emaphakathi yokulinganisa.

Isishumeki, njengengxenye yokuqoqwa kolwazi yesimo sokusebenza kwemoto, sixhunywe kumotho ngokufaka imishini.Ezimweni eziningi, isisekelo sesishumeki kanye ne-shaft yokunqamula kudingeka kwengezwe enjini.Ukuze kuqinisekiswe ukusebenza kahle nokuphepha kokusebenza kwezimoto kanye nokusebenza kwesistimu yokutholwa, imfuneko ye-coaxiality ye-encoder end connection shaft kanye ne-shaft eyinhloko iyisihluthulelo senqubo yokukhiqiza.
