Yintoni i-commutator?

I-commutator sisixhobo sombane esisetyenziswa kwi-Imoto yeDCUmsebenzi wayo kukutshintsha indlela yamandla ombane kwimoto, ngaloo ndlela itshintsha indlela yokujikeleza kwemoto. Kwimoto ye-DC, indlela yamandla ombane kufuneka itshintshe rhoqo ukuze kugcinwe indlela yamandla ombane ejikeleza ngayo. Umsebenzi we-commutator kukutshintsha rhoqo indlela yamandla ombane xa imoto ijikeleza, ukuze imoto iqhubeke nokujikeleza ngokuzinzileyo.

Umgaqo osisiseko we-commutator kukusebenzisa iseti yeeswitshi zoomatshini kunye neekhonkco zombane ukutshintsha indlela yokuhamba kombane. Xa i-motor ijikeleza, i-commutator ilawula ukuvulwa nokucinywa kombane ngokwendawo kunye necala lokujikeleza kwe-rotor, ngaloo ndlela itshintsha indlela yombane. Olu hlobo lwe-commutator yoomatshini ludla ngokusetyenziswa kwiimoto ze-DC ezinamandla amancinci, ezifana nezixhobo zasekhaya, izixhobo ezincinci zoomatshini, njl.

Kwimoto ye-DC yesiqhelo, i-commutator idla ngokuba namacandelo aliqela: i-armature, ii-poles, i-commutator kunye nee-brushes. I-armature yinxalenye ejikelezayo yemoto, kwaye ii-magnetic poles yinxalenye ye-stator yemoto. I-commutator ineseti yeeswitshi zoomatshini kunye noonxibelelwano bombane apho ulwalathiso lombane lutshintshwa khona. I-brush yinxalenye edibanisa umbane kunye nemoto, kwaye ingenise umbane kwi-coil yemoto ngebrashi.

Ukongeza kwii-commutator zoomatshini, ii-DC motors zanamhlanje zisebenzisa kakhulu iteknoloji ye-electronic commutation. Iteknoloji ye-electronic commutation isebenzisa isilawuli se-elektroniki ukutshintsha indlela yangoku, ngaloo ndlela ifezekisa i-commutation yemoto. Xa ithelekiswa nee-commutator zoomatshini, iteknoloji ye-electronic commutation ichanekileyo kwaye ithembekile, kwaye inokufikelela kulawulo lwe-commutation oluchanekileyo ngakumbi. Ke ngoko, isetyenzisiwe kakhulu kwezinye izicelo ezifuna ukuchaneka okuphezulu kwe-commutation.

I-commutator idlala indima ebalulekileyo kwiimoto ze-DC, ichaphazela ukusebenza kakuhle kwemoto, ukusebenza kakuhle kunye nokuthembeka kwayo. I-commutator elungileyo inokuqinisekisa ukuba imoto isebenza ngokuzinzileyo nangokufanelekileyo, kwaye yandisa ubomi benkonzo yemoto. Ke ngoko, uyilo, ukwenziwa kunye nokugcinwa kwe-commutator kubaluleke kakhulu.

Ngokuqhubeka kweteknoloji, uyilo kunye neteknoloji yokuvelisa ii-commutators nazo ziphucuka rhoqo, kwaye ubuchwepheshe obutsha be-electronic commutation buyaqhubeka nokuvela, okwenza ukusetyenziswa kwee-commutators kwiimoto ze-DC kube lula kwaye kuthembeke. Kwixesha elizayo, njengoko ubuchwepheshe beemoto bukhula, ii-commutators ziya kuqhubeka ziphuculwa kwaye ziphuculwe ukuze zihlangabezane neemfuno zesicelo ezitshintshayo.
