Koomatshini DC: umgaqo amanyathelo

umatshini zombane - isixhobo lokuguqula amandla ombane abe ngamandla ngoomatshini (and vice versa). Ukusebenza umatshini DC isekelwe phezu komthetho yoqheliso electromagnetic.

Ngokuqhelekileyo, ezi iiyunithi ezisetyenziswayo kwishishini iindlela ibambelele, ezifana milenge kunye ukhwelisa. A ethile ebalulekileyo injini ukuyilwa coke phezu iibhrashi mbuthi. Ukunqanda arcing ngokugqithiseleyo, kuyimfuneko ukuhlola ngamathuba athile kwaye enze umsebenzi yesondlo. DC izixhobo Umatshini yohlukile olungenangqamaniso kunye Iimoto yolunye.

Phakathi izibonda, ukudala wampompoza rhoqo ngemagnethi, lo armature ihleliwe ngokohlobo njengesilinda ngentsimbi. vee zakhe zibekwa nocingo ucingo lobhedu, neziphelo umqhubi anxulumene nakwisiqingatha amakhonkco, apho ingadibani kwezinye iinxalenye kumatshini - oku umqokeleli apho iibhrashi andahexa. Bona ezifakelwe elijikeleza ngaphandle.

Ekubeni ohlobo kwemikhosi electromotive, iankile DC umatshini iqala ku gqiba ekudibaneni kwe jiko yayo entsimini.

Ngenxa yokuba i induction magnetic sinikwa ngokufanayo kwi cylinder sentsimbi ke, isantya amandla electromotive kwenziwe ixhomekeke lexinene zangoku kwi izithuba phakathi ambuyise. Ngenxa yoko, phantsi izibonda ubuninzi Imagnethi yoqheliso, kwaye iankile iziko (kwi esqwini longitudinal) - ngu zero.

Xa umatshini DC armature iyajikeleza yonke isiqingatha-turn abaqhubi wokwephuka-umva, njengoko ukuwa phantsi kweempembelelo izibonda esahlukileyo, ngoko, ulwalathiso amandla electromotive iya kupheliswa, kwaye ukuba EMF batshintshwa ngexesha nolwalathiso, ngoko ke kufanele sibekelwe ixabiso variable. Isekethe external component rhoqo weza koomatshini DC yenziwe mbuthi isixhobo. Le - uhlobo lwe iswitshi. iibhrashi zokubhala, abaqhagamshelwe isekethe yangaphandle, thambekisa sikwisiqingatha-amakhonkco emibonweni ntsho ankile.

Ukujikeleza armature engena qhagamshelana kuphela brush, leyo phantsi wokwephuka ethile. Ngelo xesha xa ulwalathiso utshintsho amandla electromotive, oko sokuyivula amakhonkco, oko kukuthi, ukutshintsha isiphaluka lwangaphandle kwicala EMF lungenzeki. Ngoko ke, lo umqokeleli - lo rectifier, nto leyo ethintela yangoku utshintsho-generated.

Ukuze kupheliswe pulsation yomkhosi electromotive kwi-ankile zizinto iyala ukuba idityaniswe iperi plates umqokeleli. Jiko ke lwaye ukusuka komunye imo yekona kancinane, oko ivumela ukuvala ubugqwetha kunye nokungena harmonic zangoku kwi kwisekethe ngaphandle pulsation.

Ukuba koomatshini DC asebenza kwimo motor, ngoxa, icala, amandla ombane ayi lusetyenziswa zobuciko. Ngaloo ndlela, acandacanda umqokeleli ngoku tihamba jiko, nto leyo idala lentsimi yayo ngemagnethi. Ngokusebenza ndawonye nentsimi esibondeni, iankile uqala ku gqiba, Noko ke, ngelo xesha xa ulwalathiso ukujikeleza xa edlula abaqhubi kwipali malunga kwakuza kufuneka itshintshwe, isixhobo sokuqokelela nangoku sokuyivula wokwephuka. Ngoko ke, ukutshintsha ngakwicala lwangoku , yaye ngaloo ndlela lentsimi yayo ngemagnethi. Kulo mzekelo, isixhobo sokuqokelela - oku ke inverter, inverter DC kwi AC.
