Kutheni kufuneka kufakwe i-encoder kwi-motor? Sisebenza njani isifaki khowudi?

Ngexesha lokusebenza kwenjini, ixesha lokwenyaniukubeka esweniIiparamitha ezinje ngoku, isantya, kunye nendawo ehambelanayo yeshaft ejikelezayo kwicala elijikelezayo, ukufumanisa imeko yomzimba wemoto kunye nezixhobo eziqhutywayo, kunye nokulawula ngakumbi ubume bemoto kunye nezixhobo ngexesha langempela, ukuze kuqatshelwe i-servo, ummiselo wesantya, njl njl. Imisebenzi ethile emininzi.Apha, usebenzisa i-encodernjengento yokulinganisa isiphelo sangaphambili ayenzi lula kuphela inkqubo yokulinganisa, kodwa ichanekile, ithembekile kwaye inamandla.

I-encoder yinzwa ejikelezayo eguqula indawo kunye nokufuduka kweendawo ezijikelezayo zibe luchungechunge lweempawu ze-digital pulse. Ezi zibonakaliso ze-pulse ziqokelelwa kwaye zicutshungulwe yinkqubo yokulawula, kwaye uluhlu lwemiyalelo lukhutshwa ukulungelelanisa nokutshintsha imeko yokusebenza kwezixhobo.Ukuba i-encoder idityaniswe ne-gear rack okanye i-screw screw, ingasetyenziselwa ukulinganisa indawo kunye nokufuduswa kwamalungu ahambayo ahambayo.

Ii-encoders zisetyenziswa kwiinkqubo zempendulo yesignali yemveliso yemoto, umlinganiselo kunye nezixhobo zokulawula. I-encoder yenziwe ngamacandelo amabini: i-optical code disc kunye nomamkeli. Iiparamitha eziguquguqukayo ezibonakalayo eziveliswa ngokujikeleza kwe-disc yekhowudi ye-optical ziguqulwa zibe yiparameters zombane ezihambelanayo, kwaye iimpawu eziqhuba izixhobo zamandla ziphuma nge-preamplifier kunye nenkqubo yokucwangcisa uphawu kwi-inverter. .

Ngokubanzi, i-encoder ejikelezayo inokubuyisela umva isiginali yesantya, ethelekiswa nexabiso elibekiweyo kwaye ibuyiselwe kwiyunithi yokuphumeza i-inverter ukulungisa isantya semoto.

Ngokomgaqo wokufumanisa, i-encoder inokwahlulwa ibe yi-optical, magnetic, inductive kunye ne-capacitive. Ngokwendlela yayo yesikali kunye nefom yemveliso yomqondiso, inokwahlulwa ibe ziindidi ezintathu: i-incremental, absolute kunye ne-hybrid.

I-encoder eyongeziweyo, indawo yayo inqunywe ngenani lee-pulses ezibalwe ukusuka kuphawu lwe-zero; iguqula i-displacement ibe ngumqondiso wexesha lombane, kwaye emva koko iguqule isignali yombane ibe yi-pulse count, kwaye inani le-pulses limele ukufuduka; ngokupheleleyo Ukufundwa kwekhowudi yokuphuma kwendawo nganye ngaphakathi kwesangqa kuyingqayizivele, kwaye i-one-to-one imbalelwano kunye neyona ndawo ayiyi kulahleka xa amandla enqanyuliwe.Ngoko ke, xa i-encoder eyongezelelweyo icinyiwe kwaye ivuliwe kwakhona, ukufundwa kwendawo kungoku; indawo nganye ye-encoder epheleleyo ihambelana nekhowudi ethile yedijithali, ngoko ixabiso layo elibonisiweyo lihambelana kuphela nezikhundla zokuqalisa kunye nokuphela komlinganiselo, ngelixa lingenanto yakwenza nenkqubo ephakathi yokulinganisa.

I-encoder, njengento yokuqokelela ulwazi lwemotor eqhubayo, iqhagamshelwe kwi-motor ngofakelo lomatshini. Kwiimeko ezininzi, isiseko se-encoder kunye ne-terminal shaft kufuneka yongezwe kwi-motor.Ukuze kuqinisekiswe ukusebenza kunye nokukhuseleka kokusebenza kwemoto kunye nokusebenza kwenkqubo yokufumana, imfuno ye-coaxiality ye-encoder end connection shaft kunye ne-shaft engundoqo iyisitshixo kwinkqubo yokuvelisa.
