Ma inductors omwe amagwiritsidwa ntchito pamagalimoto

Ma coil ochititsa chidwi, monga zida zoyambira pamabwalo, amagwiritsidwa ntchito kwambiri pamagalimoto, monga ma valve solenoid, ma mota, ma jenereta, masensa, ndi ma module owongolera.Kumvetsetsa magwiridwe antchito a ma coils molondola kumayala maziko olimba odziwa bwino mfundo zogwirira ntchito za zigawozi.

Ntchito ya ma inductors a ma switches owongolera magalimoto.Inductor yomwe imagwiritsidwa ntchito pamagalimoto ndi imodzi mwazinthu zitatu zofunika kwambiri m'mabwalo.

Ma inductors omwe amagwiritsidwa ntchito pamagalimoto amagwiritsidwa ntchito makamaka m'magawo akulu awiri otsatirawa: zinthu zamagetsi zamagetsi, monga zomvera zamagalimoto, zida zamagalimoto, kuyatsa magalimoto, ndi zina. monga ABS, ma airbags, makina owongolera mphamvu, chiwongolero cha chassis, GPS, ndi zina zambiri.

Chifukwa chachikulu chomwe ma inductors omwe amagwiritsidwa ntchito m'magalimoto amagwiritsidwa ntchito kwambiri pamakampani amagalimoto ndi chifukwa cha malo omwe amagwirira ntchito movutikira, kugwedezeka kwakukulu, komanso kutentha kwambiri.Chifukwa chake, gawo laling'ono lakhazikitsidwa kuti lithandizire zida zamagetsi kuti zilowe mumakampani awa.

Ma inductors angapo omwe amagwiritsidwa ntchito kawirikawiri ndi ntchito zawo.Msika wamagetsi aku China wamagalimoto walowa munthawi yachitukuko chofulumira, ndikuyendetsa kufunikira kwa maginito.Chifukwa cha malo ogwirira ntchito movutirapo, kugwedezeka kwakukulu, komanso kutentha kwagalimoto komwe kumafunikira, zomwe zimafunikira pakupanga maginito ndizovuta kwambiri.

Pali mitundu ingapo yodziwika bwino yama inductors yamagalimoto:

1. High panopa inductance

Dali Electronics yakhazikitsa makina opangira magalimoto okhala ndi kukula kwa 119, omwe angagwiritsidwe ntchito pa kutentha kwa -40 mpaka + 125 madigiri.Pambuyo pogwiritsira ntchito magetsi a 100V DC pakati pa coil ndi magnetic core kwa mphindi imodzi, panalibe kuwonongeka kwa insulation kapena kuwonongeka R50 = 0.5uH, 4R7 = 4.7uH, 100 = 10uH inductance value.

2. SMT mphamvu inductance

Inductor yamagalimoto iyi ndi CDRH series inductor, yokhala ndi voteji ya 100V DC yomwe imagwiritsidwa ntchito pakati pa coil ndi maginito pachimake, komanso kukana kwa insulation yopitilira 100M Ω The inductance values ​​for 4R7=4.7uH, 100=10uH, and 101=100uH.

3. Ma inductors amphamvu amakono, apamwamba kwambiri amagetsi amagetsi amagetsi

Makina opangira magetsi omwe angotulutsidwa kumene pamsika ndi oyenera kuyimitsa magalimoto amagetsi omwe amafunikira magetsi apamwamba komanso kusefa, okhala ndi ma inductance kuyambira 6.8 mpaka 470?H. Zomwe zidavotera pano ndi 101.8A.Dali Electronics imatha kupereka zinthu zosinthidwa makonda zomwe zimatengera makasitomala.

Kuchokera pazatsopano zomwe zili pamwambapa zamagawo amagetsi amagetsi amagetsi, zitha kuwoneka kuti pakuchulukitsidwa kwa ntchito zambiri zamagetsi zamagetsi zamagalimoto, zida zamaginito zikukula kupita kufupipafupi, kutayika kochepa, kukana kutentha kwambiri, komanso kuthekera kolimba kotsutsana ndi kusokoneza.Dali Electronics yapeza zotsatira zochititsa chidwi pama inductors/transformers zamagalimoto.

Nazi zina mwa ntchito za ma inductors amagetsi: Kutsekereza komwe kulipo: Mphamvu yamagetsi yodzipangira yokha mu koyilo nthawi zonse imatsutsana ndi kusintha kwa koyilo.Itha kugawidwa m'makoyilo otsamwitsa othamanga kwambiri komanso ma coko otsika pafupipafupi.

Kukonza ndi kusankha pafupipafupi ntchito: Ma coil ochititsa chidwi ndi ma capacitor amatha kulumikizidwa limodzi kuti apange chigawo chowongolera cha LC.Ngati ma frequency oscillation achilengedwe f0 a dera ndi ofanana ndi ma frequency f a siginecha ya AC, ndiye kuti inductance ndi capacitance ya dera ndizofanana.Chifukwa chake, mphamvu yamagetsi yamagetsi imayenda mmbuyo ndi mtsogolo pakati pa inductance ndi capacitance, chomwe ndi chodabwitsa cha dera la LC.Panthawi ya resonance, chifukwa cha kufanana kosiyana pakati pa inductance ndi capacitance ya dera, inductance ya chiwerengero chonse mu dera ndi yaying'ono kwambiri ndipo panopa ndi yaikulu (ponena za chizindikiro cha AC ndi f = f0).Chifukwa chake, dera la LC resonant lili ndi ntchito yosankha ma frequency ndipo lingasankhe chizindikiro cha AC ndi pafupipafupi f.
