Electromagnetic coil 14550884 na Volvo excavator

Shirya manyan alamun ayyuka

Fihirisar aiki na inductance coil shine yafi girman inductance. Bugu da kari, gabaɗaya magana, raunin waya tare da inductance coil koyaushe yana da takamaiman juriya, wanda yawanci ƙanƙanta ne kuma ana iya yin watsi da shi. Sai dai a lokacin da na’urar da ke gudana a wasu da’irori ya yi girma sosai, ba za a yi watsi da wannan ‘yar juriya ta na’urar ba, domin babban igiyar wutar lantarki za ta yi amfani da wutar da ke kan na’urar, wanda hakan zai sa na’urar ta yi zafi ko ma ta mutu, don haka wani lokaci wutar lantarkin ke yi. Ya kamata a yi la'akari da ikon da nada zai iya jurewa.

Inductance

Inductance l yana wakiltar ainihin halaye na nada kanta, ba tare da la'akari da halin yanzu ba. Sai dai naɗaɗɗen inductance na musamman (inductance mai launi mai launi), gabaɗayan inductance ba a yi masa alama ta musamman akan coil ba, amma an yi masa alama da takamaiman suna. Inductance, wanda kuma aka sani da coefficient na kai-inductance, adadi ne na jiki wanda ke nuni da ikon inductance na inductor. Inductance na inductor ya dogara ne akan adadin jujjuyawar coil, yanayin iska, kasancewar ko rashi na ainihin da kayan abin da ke cikin, da sauransu. Gabaɗaya, ƙarin jujjuyawar jujjuyawar na'urar tana da rauni, mafi girma da inductance. Inductance na nada da Magnetic core ya fi girma fiye da na nada ba tare da Magnetic core; Mafi girman ƙarfin maganadisu na ainihin, mafi girman inductance.

Babban sashin inductance shine Henry (Hen a takaice), wanda harafin "H" ke wakilta. Raka'o'in da aka fi amfani da su sune milli-Heng (mH) da micro-Heng (μH), kuma alaƙar da ke tsakanin su ita ce:

1H=1000mH

1mH=1000μH

Inductive reactance

Girman juriya na inductance coil zuwa AC halin yanzu ana kiransa inductance XL, tare da ohm a matsayin naúrar da ω a matsayin alama. Dangantakarsa da inductance L da AC mitar F shine XL=2πfL.

Halin inganci

Ma'anar ingancin Q shine adadin jiki wanda ke wakiltar ingancin coil, kuma Q shine rabon inductance XL zuwa juriya ɗaya, wato, Q = XL/R. inductor yana aiki a ƙarƙashin takamaiman mitar AC. Mafi girman ƙimar Q na inductor, ƙarami asarar kuma mafi girman inganci. Ƙimar q na coil yana da alaƙa da juriya na DC na mai gudanarwa, asarar dielectric na kwarangwal, asarar da garkuwa ko baƙin ƙarfe ya haifar, tasirin tasirin fata mai girma da sauran dalilai. Ƙimar q na nada yawanci dubun zuwa ɗaruruwa ne. Halin ingancin inductor yana da alaƙa da juriya na DC na na'urar na'ura, asarar dielectric na firam ɗin coil da asarar da cibiya da garkuwa suka haifar.
