Ngabe umkhuthaza ushintsha i-AC ku-DC?

Esikhathini sezinkinga zikagesi, TheomakhelwanaIngxenye ebalulekile ku-DC Generator kanye nama-DC Motors. Ngenkathi indima yayo ingabonakala iyinkimbinkimbi, ukuqonda umsebenzi wayo kunganikeza ukuqonda okubalulekile kokuthi la madivayisi asebenza kanjani. Ngokukhethekile, umhlangano udlala indima ebalulekile ekuguquleni ugesi wamanje kusuka kwelinye ifomu uye kwelinye. Kepha ingabe umkhuthazo ushintsha i-AC ku-DC? Ake sihlole lo mbuzo ngemininingwane eminingi.

Okokuqala, kubalulekile ukuqonda umehluko phakathi kwe-AC (Ukushintsha kwamanje) ne-DC (eqondile yamanje). I-AC ibonakala nge-waveform ye-sinusoidal eshintsha ngokuqondile ngokuhamba kwesikhathi, ngenkathi i-DC igeleza isiqondiso esisodwa kuphela. Ngokwesimo sabakhiqizi be-DC kanye nama-motors, umhlangano ubalulekile ekuguquleni amanje phakathi kwalezi zinhlobo ezimbili.

Ku-generator ye-DC, umkhuthazo ukhonza ukuguqula i-AC ekhiqizwe kuma-armature windings abe yi-DC. Njengoba i-armature ijikeleza emandleni kazibuthe, ikhiqiza i-ac voltage emaphethelweni ayo. Umzila, ngokuhlangana namabhulashi, uqoqa lolu moya we-AC futhi uliguqulele abe yi-DC ngokubuyisa ubukhosi bokukhishwa kwayo yonke ingxenye yomjikelezo. Le nqubo iqinisekisa ukuthi i-voltage ekhishwayo ihlala ihlala isendleleni, ngaleyo ndlela kukhiqize i-DC.

Ngakolunye uhlangothi, ngemoto ye-DC, iomakhelwanaidlala indima efanayo kodwa ehlukile kancane. Ngenkathi imoto inikwa amandla yi-DC, umkhuthazo usetshenziselwa ukuguqula le DC ibe yi-AC ngaphakathi kwe-Windings ye-armature. Lokhu kungahle kubonakale ku-countertuitive, njengoba i-DC Motors inikwa amandla yi-DC, kepha inqubo iyadingeka ukuze imoto isebenze kahle. Njengoba i-armature ijikeleza, umqhubisi kanye namabhulashi asabalalisa okufakwayo kwe-DC okwamanje emandleni okuhlobisa ama-armature ngendlela yokuthi kwakha amandla kazibuthe emoto. Lesi sikhandla kazibuthe se-AC sisebenzisana nama-motor's Magnets anaphakade, okwenza i-armature ijikeleze futhi ikhiqize i-torque.

Kuzona zozimbili lezi zigameko, umkhuthazo ubalulekile ekuguquleni amanje phakathi kwe-AC ne-DC. Kodwa-ke, kubalulekile ukuqaphela ukuthi i-commutaster ngokwayo ayiguquli ngokomzimba okukhona kusuka ku-AC ku-DC noma okuphambene nalokho. Esikhundleni salokho, kuncike ekushintsheni kwemishini kwe-armature kanye nokwakhiwa kwamabhulashi ukufeza lokhu kuguqulwa.

Le khasiongumhambiIdizayini ibalulekile ngomsebenzi wayo. Ngokuvamile kuqukethe indawo ehlukaniswe yingxenye ye-cylindrical eyenziwe ngethusi noma enye impahla esebenzayo. Lezi zingxenye zifakwa komunye nomunye futhi zixhunyiwe ku-armature windings. Njengoba i-armature ijikeleza, amabhulashi agibela phezu komhambi, axhumane nezigaba ezihlukile futhi asabalalise okulungile.
