Umehluko phakathi kwe-optical encoder (isikali se-grating) nesishumeki kazibuthe (isikali sikazibuthe).

1.I-Optical Encoder(Isikali Sokugreyitha):

Isimiso:
Isebenza ngokusekelwe ezimisweni ze-optical. Ivamise ukuhlanganisa ama-grating bar akhanyayo, futhi uma ukukhanya kudlula kulawa mabha, kukhiqiza amasiginali we-photoelectric. Indawo ikalwa ngokuthola izinguquko kulawa masignali.

Ukusebenza:
Ii-optical encoderikhipha ukukhanya, futhi njengoba idlula ezindongeni zokugaya, umamukeli uthola izinguquko ekukhanyeni. Ukuhlaziya iphethini yalezi zinguquko kuvumela ukunqunywa kwesikhundla.

I-Magnetic Encoder (Isikali sikaMagnetic):

Isimiso:
Isebenzisa izinto kazibuthe nezinzwa. Ngokuvamile kuhlanganisa imicu kazibuthe, futhi njengoba ikhanda kazibuthe lihamba kule micu, lidala izinguquko endaweni kazibuthe, ezitholwa ukukala indawo.

Ukusebenza:
Ikhanda kazibuthe lesishumeki sekhodi lizwa izinguquko endaweni kazibuthe, futhi lolu shintsho luguqulwa lube amasignali kagesi. Ukuhlaziya lezi zimpawu kuvumela ukunqunywa kwesikhundla.

Uma ukhetha phakathi kwezishumeki ezibonayo nezikazibuthe, izici ezifana nezimo zemvelo, izidingo zokunemba, nezindleko zivame ukucatshangelwa.Izifaki khodi zamehlozilungele izindawo ezihlanzekile, kuyilapho izifaki khodi kazibuthe zizwela kancane othulini nasekungcoleni. Ukwengeza, izifaki khodi zokubona zingase zilungele izinhlelo zokusebenza ezidinga izilinganiso zokunemba okuphezulu.
