I-Electromagnetic
Ama-motors e-Electromagnetic DC aqukethe izingongolo ze-stator, i-rotor (i-armature), i-commutator (eyaziwa kakhulu njenge-commutator), amabhulashi, ikesi, amabombo, njll.
Izigxobo ze-stator kazibuthe (izingongolo eziyinhloko kazibuthe) zemoto kagesi kagesi kagesi zakhiwe ngomgogodla wensimbi nogqozi lokuthakazelisa. Ngokuya ngezindlela ezahlukahlukene zokuzijabulisa (ezibizwa ngokuthi yi-excitation ngokwezinga elidala), ingahlukaniswa ngamamoto we-DC athokoze ngochungechunge, ama-motors ajabulisayo e-DC, ama-motors e-DC ahlukaniswe ngokwahlukana nama-motors e-DC ahlanganisiwe. Ngenxa yezindlela ezahlukahlukene zokuthakazelisa, umthetho we-stator magnetic pole flux (owenziwe yikhoyili yenjabulo yesigxobo se-stator unikwe amandla) nawo uhlukile.
Ukugoqelwa kwensimu nokugudlulwa kwe-Rotor yemoto e-DC-exhumekile ixhunywe ochungechungeni ngokusebenzisa ibhulashi kanye nomgibeli. Okwamanje kwenkambu kuyalingana nesikhathi samanje sezikhali. I-static flux ye-stator iyanda ngokwanda kwensimu yamanje, futhi i-torque ifana namandla kagesi. I-armature yamanje ilingana nesikwele samanje, futhi ijubane lehla ngokushesha njengoba i-torque noma yamanje inyuka. I-torque yokuqala ingafinyelela ngaphezu kwezikhathi ezi-5 ze-torque elinganisiwe, futhi i-torque yesikhashana esinqunyiwe ingafinyelela ngaphezu kwezikhathi ezi-4 ze-torque elinganisiwe. Izinga lokushintsha kwejubane likhulu, futhi ijubane elingenawo umthwalo liphezulu kakhulu (imvamisa alivunyelwe ukusebenza ngaphansi komthwalo). Ukulawulwa kwejubane kungatholakala ngokusebenzisa ama-resistors angaphandle nochungechunge lwe-windings ochungechungeni (noma ngokufana), noma ngokushintsha ama-windings ochungechunge ngokufana.

Ukujija okujabulisayo kwe-DC motor e-shunt-excited ixhunywe ngokufana ne-rotor emazombezombe, i-current excitation ayiguquki njalo, i-torque yokuqala ilingana nesikhathi samanje sokuzivikela, kanti i-current yamanje icishe ibe ngu-2.5 izikhathi zamanje ezilinganisiwe. Ijubane lehla kancane ngokwanda kwe-torque yamanje kanye ne-torque, kanti i-torque yesikhathi esifushane yokugcwala ngokweqile izikhathi eziyi-1.5 ze-torque elinganisiwe. Izinga lokushintshwa kwejubane lincane, lisuka ku-5% liye ku-15%. Ijubane lingalungiswa ngokwenza buthakathaka amandla engaguquguquki kazibuthe.
Ukushaywa komoya okwehlukanisayo kwe-DC motor kuxhunywe kungesi ezimele yokuhambisa, futhi amandla ayo okuzijabulisa ahlala njalo, futhi i-torque yokuqala ilingana namandla wamanje wezikhali. Ushintsho lwejubane nalo luyi-5% ~ 15%. Ijubane lingakhuphuka ngokwenza buthakathaka amandla kazibuthe namandla angaguquki noma ngokunciphisa amandla we-rotor emazombezombe ukunciphisa ijubane.
Ngaphezu kokugudluzwa kwe-shunt ezigxotsheni ze-stator zemoto ye-DC ejabule kakhulu, kukhona futhi ama-windings athokoziswe ngochungechunge axhunywe ochungechungeni nama-rotor windings (inani lokujika lincane). Ukuqondiswa kokuhamba ngamandla kazibuthe okukhiqizwe ngochungechunge lokugwingciza kuyefana nokwajika okuyinhloko. I-torque yokuqala icishe iphindwe kane i-torque elinganisiwe, kanti i-torque yesikhashana esinqunyiwe icishe iphindwe kathathu ku-torque elinganisiwe. Izinga lokushintsha kwejubane lingu-4% ~ 3.5% (lihlobene nokugudluza uchungechunge). Ijubane lingalungiswa ngokwenza buthakathaka amandla kazibuthe.
Ingxenye yesiguquli se-commutator yenziwa ngezinto ze-alloy ezifana nesiliva-ithusi, i-cadmium-copper, njll., Futhi ibunjiwe ngepulasitiki enamandla amakhulu. Amabhulashi athintana ngokushelelayo nomgibeli ukuze anikeze i-armature yamanje yama-rotor windings. I-Electromagnetic DC motor brushes ngokuvamile isebenzisa amabhulashi ensimbi noma i-electrochemical graphite brushes. Umgogodla wensimbi we-Rotor wenziwe ngamashidi wensimbi enamathele, ngokuvamile anezikhala eziyi-12, ezinamasethi ayi-12 ama-armature ahlanganisiwe kuwo, futhi ngemuva kokuthi i-winding ngayinye ixhunywe ochungechungeni, bese ixhunywe kumapuleti angu-12 ngokulandelana.

Imoto evumelanisiwe iyimoto ejwayelekile ye-AC njengemoto yokungeniswa. Isici sithi: ngesikhathi sokusebenza okuqinile, kunobudlelwano obuqhubekayo phakathi kwejubane le-rotor kanye nemvamisa yegridi n = ns = 60f / p, kanti i-ns iba isivinini sokuvumelanisa. Uma imvamisa yegridi yamandla ingashintshi, ijubane lezimoto ezivumelanisayo esimweni esizinzile lihlala likhona kungakhathalekile ukuthi ubukhulu bomthwalo bunjani. Ama-motor ahambisanayo ahlukaniswe ngama-generator ahambisanayo nama-motor ahambisanayo. Imishini ye-AC ezitshalweni zamandla zesimanje ikakhulukazi izinjini ezihambisanayo.
