Inductance Coil Guide: Mashandiro Ayo & Nei Zvichikosha
Kunzwisisa Inductance Coils: The Basics
Nhanganyaya yeInductance
Iyo induction ndiyo yakakosha parameter yedunhu remagetsi inoyera kugona kwedunhu kuchengetedza simba kana yazvino ichityairwa nepadunhu. Iyo chaiyo pfungwa pano ndeye electromagnetic induction mune conductor: ikozvino inoshandurwa, voltage inooneka pairi. Midziyo inozivikanwa semainductor kana inductor coils inoshandisa ichi chiito. Anowanzo kugadzirwa newaya yakaputirwa nepakati inogona kunge iri mhepo, simbi kana mamwe magineti. Nhamba yekutendeuka uye iyo yakakosha zvinhu ndizvo zvekutanga zvinotemerwa zveinductor's inductance. Kuziva mashandiro anoita inductance kwakakosha kuti unzwisise kuti inductors inoshanda sei mune mamwe maapplication emagetsi.
Zvikamu zveInductance Coil
Coil of inductance iwaya inofambisa yakamonerwa mudenderedzwa uye nepakati panokuvadzwa waya. Iyo yekuitisa chidimbu inogona kunge iri waya yemhangura, waya yemhangura inoshandiswa zvakanyanya nekuda kweiyo yakanaka magetsi conductibility uye kugadzira kugona. Iyo yakakosha zvinhu inogona kusiana pamusoro pehupamhi zvichienderana neinodiwa maitiro eiyo inductance coil uye zvinokwanisika kushandisa mhepo, ferrite, simbi uye hupfu simbi sechinhu chepakati. Sezvo imwe neimwe iri yeyakasiyana magineti permeability, ivo vanopesvedzera iyo coil inductance yega. Heino tafura yezvakajairwa core zvinhu uye yavo Relative permeability.
| Core Material | Relative Permeability | Common Use |
| Air | 1 | High-frequency applications |
| Ferrite | 1,000 - 15,000 | Broad range, kubva kuRF kusvika kumagetsi emagetsi |
| Iron | 200 - 10,000 | Magetsi emagetsi, inductors |
| Silicon Steel | 4,000 - 6,000 | AC magetsi ekushandisa, mota cores |
| Amorphous Metal | 10,000 - 20,000 | High-effective transformers |
Basa reInductance Coils mumasekete
Inductance coils zvinhu zvakakosha mumaseketi emagetsi sezvavanogona kuchengeta uye kuburitsa simba, masaini masaini, anopa kuzviparadzanisa nevamwe. Apo magetsi anofamba kuburikidza ne inductor, magnetic field inogadzirwa yakakomberedza coil. Iyi chengetedzo yesimba inogona kukwevera simba kudunhu kana zvichidikanwa, uye inobatsira pakuita kudzora kwakakwana kwekusiyana kwemagetsi ekupa. Mainductors anoshandiswawo mumasefa anovharisa ruzha rwepamusoro-soro uye anobvumidza yakananga ikozvino (DC) uye yakaderera-frequency masaini kuti apfuure. Iwo anoshandiswa mumashanduri ekufambisa simba pakati pemaseketi maviri kana anopfuura pasina kushandiswa kwevanobatika. Muchirevo chechinyorwa ichi, tsananguro chaiyo yemafambiro einduction coils inodiwa pakugadzira uye kuenzanisira kwenhamba huru yezvigadzirwa zvemagetsi uye masisitimu.

Air Core Coils vs. Iron Core Coils
Mhepo nesimbi core inductance coils - iwo maviri ekutanga marudzi ekugadzira kana zvasvika kune nyika yemagetsi emagetsi. Air coreInductors.Wikipedia Tsanangudzo Mhepo yepakati coils (iyo ine mhepo iri chinhu chadzo chepakati) inoshandisa musimboti weinductor uye zvakare iri nyore nzira yeindukita. Sezvo vasina ferromagnetic core, ivo havana kujaira ku core saturation uye havana kurasikirwa kwe hysteresis uye nekudaro vanobatsira mu-high-frequency application (senge radio transmission). Kusiyana neizvi, simbi yepakati coil inosanganisira musimboti une ferromagnetic zvinhu izvo zvinowedzera zvakanyanya inductance yecoil mukupindura kune magineti maitiro epakati zvinhu. Izvi zvinovaita kuti vanyatsoshanda mukufambisa kwesimba uye kuchengetedza zvikumbiro asi ndezvekusakosha kana zvasvika pakurasikirwa kwakawedzera kunokonzerwa needdy currents uye hysteresis kunyanya munzvimbo yakakwirira yefrequency.
Variable Inductance Coils
Variable Inductance Coils inopa mukana wekushandura kukosha kwayo inductance uye kuienzanisa neinodiwa yedunhu kuendesa kuita kwakanyanya. Makoiri akadaro anowanzo kuve neinotsvedza-musimboti inogona kufambiswa kushandura kuswedera kwepakati nemhepo yekoiri, uye nekudaro shandura magineti flux linkage uye nekudaro inductance. Iyi tunability yakakosha muredhiyo inogamuchira uye transmitter uko dunhu rinofanirwa kunyatsotariswa kune kosi inotsanangura frequency, kana uko firita inoda kutarisisa.
Pfungwa yekusiyana inductance coils iri nyore; nekufambisa musimboti iyo coil magineti zvivakwa zvinoshandurwa uye zvinogoneka kutenderera zvine simba. Uku kuchinjika kunoita kuti vanyanyo batsira mumagetsi uko ma frequency frequency anosanganisirwa, asi inowedzera kuoma kwemakanika uye mukana wekupfeka.
Specialty Coils
Tsika inductor macoil anogadzirwa kuti agutse izvo zvinodikanwa zvekushandisa zvisina kufanirwa neyakajairwa mweya musimboti kana iron musimboti inductor dhizaini. Izvi zvinogona kuumba toroidal windings, iyo inopa kushanda kukuru uye kudzikisa EMI kunyangwe yakavharirwa loop dhizaini kana inogona kuumbwa seyakawanda-layer coil inogona kuwana yakakwira inductance kukosha mukati mevhoriyamu diki. Kune zvakare mafomu ecoil anodhindwa pamabhodhi edunhu akadhindwa (PCB) uye anoiswa pakati pePCB akaturikidzana kuchengetedza nzvimbo uye nekupa kuchinjika kwedunhu dhizaini. Yakasiyana-siyana yakakosha coils inogonesa yega mhinduro kune yakakura nhamba yekushandisa. Semuyenzaniso, toroidal coils anowanzo shandiswa mumagetsi emagetsi uye matransformer kana nzvimbo iripamusoro uye kuita kwakakosha, uye maPCB coils akajairika mumaseketi akabatanidzwa uye RFID. Izvi zvakasiyana-siyana uchapupu hwekusiyana-siyana kwema inductance coils kune zvinodiwa zvemunhu wega engineering nyaya.
Mashandiro eInductor Coils Anoshanda
Magnetic Field Generation
Sezvo simba remagetsi richipfuura nepakati inductance coil, magnetic field inoumbwa kumativi ayo. Izvi ndizvo mhedzisiro yemisimboti yemagetsi emagetsi, zvinoenderana neapi anofambisa machaji emagetsi, kureva, mafungu, anoburitsa magineti minda. Ukuru uye kutungamirirwa kweiyi magnetic field inobva pahuwandu hwemazuva ano uye kutungamira kwekuyerera kwezvino. Nekuda kwekugadzirwa kwavo, inductance coils inosimudzira chiitiko ichi, nekungopeta waya uye mukuita izvi kuwedzera iyo magineti, inova yakasimba zvakanyanya sezvo coil yega yega inowedzerwa. Iyi magineti inogadzira kugona kweiyo inductance coils yakakosha kune akawanda masisitimu emagetsi zvekuti inoumba yakakosha tekinoroji yemagetsi, ma transformer, uye inductors mumaseketi emagetsi.
Inductance mu AC uye DC Circuits
Chiito cheinductor chakasiyana chaizvo muAC uye muDC maseketi. Kana magetsi eDC akaiswa, mushure mekunge mitsara yemagetsi yemagetsi yamiswa yakatenderedza coil, iyo inductance inopesana nekuchinja kune yazvino nekudzikisa simba rinogona kuchengetwa mundima yemagineti. Asi nekuti DC haisi kushanduka, pesvedzero yemazinga e inductance kunze kwesekondi. Mune inotsinhanisa yazvino (AC) dunhu, zvisinei, umo hukuru hwazvino uye kutungamira zvinosiyana zvinoramba zvichisiyana, inductance ndiyo ine simba yakawanda. Inoenderera mberi ichirwisa shanduko idzi uye mhedzisiro inguva pakati pevoltage uye yazvino inonzi inductive reactance. Iyi nheyo yakakosha zvikuru mukuyerera kwemagetsi uye kusefa kwechiratidzo pakati pemagadzirirwo akasiyana emagetsi nemagetsi.
Zvishandiso Zvinoshanda uye Mienzaniso
Inductor coils yakajairika kune maindasitiri uye zvemazuva ese zvemagetsi. Ivo vanoita basa rakakosha mumashanduri uye vanobatsira kutsigira zvese kubva kumajaja kusvika kune emagetsi grid nekudzora mazinga emagetsi. Mumagetsi ekuteerera, ivo vanovhara kunze ruzha rusingadiwe uye vanovimbisa kujeka. Motors uye jenareta zvakare vashandisi vakakura ve inductance coils yekushandurwa kwemagetsi kuita magetsi emagetsi uye zvinopesana. Mamwe akajairwa inductance coils uye mashandisiro awo akanyorwa patafura inotevera:
| Type | Application | Advantage | Kufunga |
| Standard (Solenoid) | General Chinangwa | Dhizaini iri nyore, inogoneka | Bulky for high inductance |
| Air-core | Radio Frequency | Kurasikirwa kwakaderera pahuwandu hwepamusoro | Limited inductance range |
| Ferrite-core | Simba Transformers | Kubudirira kwepamusoro | Core saturation & kupisa |
| Toroidal | Audio Equipment | Yakakwira magineti kunyatsoshanda, yakaderera EMI | Complex winding, yakaoma kugadzira |
Kugadzira uye Kuvaka Yako Yega Inductance Coil

Nhanho-ne-Nhanho Gwaro rekuita
Kugadzira inductance coil kwakaoma. Chekutanga, tarisa huwandu hwemamhepo anodiwa kuti usvike kune chako chinangwa inductance (iyo iwe yaunogona kuona kuburikidza ne online calculator kana mafomula). Tanga nekutapa imwe mugumo we enameled waya yemhangura kusvika pakati. Mhepo wire pedyo uye zvakaenzana kumativi epakati; kuti iwe wakanaka sei pakupenengura ndiwo unosarudza mhedzisiro. Kana uchinge wapedza nema windings, chengetedza kuguma ne tepi zvakare. Wobva wabvisa simbi kubva kumativi ese ewaya yeronda netambo yekubvisa kana blade inopinza zvinyoro nyoro. Solder aya matipi kudunhu rako kana mudziyo kugadzira yakasimba yemagetsi kubatana. Chekupedzisira, tarisa inductance yecoil uchishandisa multimeter kuona kuti yakakwana.
