Umbuzo: Yintoni ukufudumala kwe-induction?
I-Basics Induction iqala nge-coil yezinto eziphathekayo (umzekelo, ubhedu). Njengoko ikhoyo ngoku ihamba kwikhoyili, intsimi yamagnetic ngaphakathi nangaphandle kwekhoyili iyaveliswa. Ukukwazi ukwenza umsebenzi wemagnethi kuxhomekeke kuyilo lwekhoyili kunye nomthamo wangoku oqukuqelayo kwikhoyili.
Ulwalathiso lwentsimi yamagnetic luxhomekeke kwindlela ehamba ngayo ngoku, ngoko ke i-current alternating ngokusebenzisa ikhoyili
iya kubangela ukuba umhlaba wemagnethi utshintshe kwicala lesantya esifana nesokujikeleza kwangoku. I-60Hz AC yangoku iya kubangela ukuba umhlaba wemagnethi utshintshe ulwalathiso amaxesha angama-60 ngomzuzwana. I-400kHz i-AC yangoku iya kubangela ukuba intsimi yamagnetic itshintshe amaxesha angama-400,000 okwesibini.Xa into eqhubayo, isiqwenga somsebenzi, sibekwe kwindawo eguqukayo yamagnetic (umzekelo, intsimi eyenziwe nge-AC), i-voltage iya kunyanzeliswa kwindawo yokusebenza. (uMthetho kaFaraday). Umbane owenziweyo uya kubangela ukuhamba kwee-electron: okwangoku! I-current flowing through workpiece iya kuhamba ngendlela echaseneyo njengangoku kwi-coil. Oku kuthetha ukuba sinokulawula ukuphindaphinda kwangoku kwindawo yokusebenza ngokulawula ukuphindaphinda kwangoku kwi
I-coil.Njengoko ikhoyo ngoku ihamba nge-medium, kuya kubakho ukuchasana nokuhamba kwee-electron. Oku kuxhathisa kubonisa njengobushushu (I-Joule Heating Effect). Izinto ezikwazi ukumelana nokuhamba kwee-electron ziya kunika ubushushu obuninzi njengoko umbane uhamba kuzo, kodwa ngokuqinisekileyo kunokwenzeka ukufudumeza izinto eziqhuba kakhulu (umzekelo, ubhedu) usebenzisa i-current induced current. Lo mcimbi ubalulekile ekufudumezweni kwe-induction. Yintoni esiyidingayo kwi-Induction Heating? Konke oku kusixelela ukuba sidinga izinto ezimbini ezisisiseko ukuze kufudunyezwe ukufudumala kwenzeke:
