Sei encoder ichifanira kuiswa pamota? Ko encoder inoshanda sei?

Panguva yekushanda kwemota, chaiyo-nguvamonitoringyemaparamita akadai seazvino, kumhanya, uye chinzvimbo cheiyo shaft inotenderera munzira inotenderedza, kuona mamiriro emuviri wemota nemidziyo inotyairwa, uye kuenderera mberi nekudzora mamiriro ekumhanya kwemota nemidziyo munguva chaiyo, kuitira kuti uzive servo, kukurumidza kudzora, nezvimwe. Mazhinji mabasa chaiwo.Pano, uchishandisa encoderseyekumberi-yekupedzisira kuyerwa haingorerutsa zvakanyanya kuyera sisitimu, asiwo ndeyechokwadi, yakavimbika uye ine simba.

Iyo encoder i sensor inotenderera inoshandura chinzvimbo uye kutamiswa kwezvikamu zvinotenderera kuita nhevedzano yedhijitari pulse masiginecha. Izvi zviratidzo zvepulse zvinounganidzwa uye zvinogadziriswa nehurongwa hwekutonga, uye nhevedzano yemirairo inobudiswa kugadzirisa uye kushandura mamiriro ekumhanya emidziyo.Kana iyo encoder yakasanganiswa negiya rack kana screw screw, inogona zvakare kushandiswa kuyera chinzvimbo uye kutamiswa kwemutsara unofamba zvikamu.

Encoder anoshandiswa mumotokari inobuda chiratidzo chemhinduro masisitimu, kuyerwa uye kudzora michina. Iyo encoder inoumbwa nezvikamu zviviri: iyo optical kodhi disc uye inogamuchira. Iyo optical variable parameters inogadzirwa nekutenderera kweiyo optical kodhi disc inoshandurwa kuita inoenderana magetsi paramita, uye masaini anotyaira magetsi emagetsi anobuda kuburikidza ne preamplifier uye chiratidzo chekugadzirisa system mune inverter. .

Kazhinji, iyo rotary encoder inogona kungodzosa chiratidzo chekumhanya, icho chinofananidzwa nehuwandu hweseti uye kudzoserwa kuinverter execution unit kugadzirisa kumhanya kwemota.

Zvinoenderana nemusimboti wekuona, iyo encoder inogona kukamurwa kuita optical, magineti, inductive uye capacitive. Zvinoenderana nechiyero chayo nzira uye chiratidzo chekubuda fomu, inogona kupatsanurwa mumhando nhatu: inowedzera, yakakwana uye yakasanganiswa.

Inowedzera encoder, nzvimbo yayo inotarirwa nehuwandu hwemapulses akaverengwa kubva kune zero mark; inoshandura kutama kuita chiratidzo chemagetsi che periodic, uyezve inoshandura chiratidzo chemagetsi mukuverenga pulse, uye nhamba yemapulisi inomiririra kutama; absolute Nzvimbo yemhando encoder inotarirwa nekuverenga kwekodhi yekodhi. Iko kubudiswa kwekodhi yekuverenga kwechinzvimbo chega chega mukati medenderedzwa yakasiyana, uye iyo-kune-imwe tsamba ine nzvimbo chaiyo haizorasikirwe kana simba rabviswa.Naizvozvo, kana iyo incremental encoder yakadzimwa uye ikabatidzwa zvakare, iyo nzvimbo yekuverenga ndeye ikozvino; imwe neimwe nzvimbo yeabsolute encoder inoenderana neimwe kodhi yedhijitari, saka kukosha kwayo kwakaratidzwa kunongoenderana nenzvimbo dzekutanga uye dzekupedzisira dzeyero, nepo Iyo isina chekuita neyepakati maitiro ekuyera.

Iyo encoder, sechinhu chekuunganidza ruzivo chemotor inomhanya state, yakabatana nemota kuburikidza nekumisikidzwa kwemichina. Muzviitiko zvakawanda, base encoder uye terminal shaft inoda kuwedzerwa kumota.Kuti uve nechokwadi chekushanda uye kuchengetedzeka kwekushanda kwemota uye yekutora system mashandiro, iyo coaxiality inodiwa ye encoder yekupedzisira yekubatanidza shaft uye shaft huru ndiyo kiyi yekugadzira maitiro.
