I-Inductor Coil Basics: Imisebenzi, Iintlobo kunye nezicelo eziphambili

Ukuqonda iikhoyili ze-Inductor

Iziseko zeeCoils ze-Inductor

Iikhoyili ze-Inductor njengezinto ezibalulekileyo kwiinkqubo ezininzi zombane, zinendima ebalulekileyo ekulawuleni ukuhamba kwamandla ombane. Bagcina amandla ngokusebenzisa umsinga wombane oqukuqela kwikhoyili ukuseka ukuguquguquka kwemagnethi kwikhoyili. Oku kubavumela ukuba babonelele ngemisebenzi ebalulekileyo, kubandakanywa ukususa ingxolo yombane enokuthi ichaphazele iisekethe kunye nokuzinzisa amandla ombane ukuthintela umonakalo kwiindawo ezibuthathaka ukusuka kwi-voltage engaphezulu. Kwaye zibalulekile ekulungiseni iisekethe kwiifrikhwensi ezithile, eneneni isiseko esisisiseko sikanomathotholo kunye nokusetyenzwa kwemiqondiso.

I-inductor yenziwe ngenxeba locingo (ngokuqhelekileyo, kodwa hayi rhoqo) malunga nombindi. Undoqo unokubandakanya umoya, i-ferrite, intsimbi, okanye ezinye izinto ezinozibuthe, nganye kuzo inokukhethwa ngokweempawu ezithile eziza kunikezelwa kwi-inductor. Umzekelo, iicores ze-ferrite zithandwa kakhulu kwizicelo ze-high-frequency ngenxa yelahleko yazo ephantsi, ngelixa ii-iron cores zinokusetyenziselwa amaxabiso azo aphezulu e-inductance kwizicelo zamandla. Inani elikhulu lee-windings (okanye ukujika) kwentambo ejikeleze i-core, i-inductance enkulu yekhoyili; ukujika okungaphezulu kocingo kukholisa ukwenza i-inductance ephezulu, kwaye oku kuvumela amandla angaphezulu ukuba agcinwe kumhlaba wemagnethi.

Kwakhona, indlela esebenza ngayo ikhoyili ekwakhiweni nasekukhululeni amandla kumiselwa yi-inductance, elinganiswe kuHenries (H). Olu phawu lubalulekile kwiinkalo ezifana nezixhobo zombane ezilula okanye i-elektroniki yedijithali, apho unomdla kulungiso olulungileyo lokudluliselwa kwamandla. Ngokhetho olunengqiqo lwezinto ezingundoqo, i-wire gauge, kunye nenani le-windings, iinjineli zinokwenza ngokwezifiso iikhoyili ze-inductor kwizicelo ezithile, ezinikezela la macandelo asebenzayo kuyilo kunye nokulungiswa kweesekethe ze-elektroniki.

Iintlobo zeeCoils ze-Inductor

Kukho iikhoyili ezininzi ze-inductor ezisetyenziselwa izizathu ezahlukeneyo kunye neenjongo. Iintlobo ezintathu eziqhelekileyo zi-air-core, i-iron-core, kunye ne-ferrite-core. I-Air-core inductors ayinayo into engundoqo kwaye ine-inductance ephantsi, kodwa ilahleko ephantsi kumaza aphezulu. Ii-inductors ezine-iron core zine-inductance enkulu kodwa zineengxaki zokuzaliswa kwe-core kunye nelahleko kwiifrikhwensi eziphezulu. I-Ferrite-core inductors yi-compromise phakathi kwezi zibini, kunye ne-inductance ephezulu kunye neelahleko ezimbalwa kwiintlobo ezahlukeneyo zefrikhwensi. Sesiphi kwezi zindululo zibini zokusetyenziswa zixhomekeke kwiimfuno zesekethe ye-elektroniki.

Iiparamitha eziphambili kunye neNgcaciso
