1. I-DC motor ye-DC

Kuma-motor ahlanganisiwe lokhu kwenziwa ngokushintshwa kwe-rotary emgodini we-motor wabiza umhlangano. Siqukethe isilinda esijikelezayo noma i-disc ihlukaniswe izingxenye eziningi zokuxhumana zensimbi ku-rotor. Izingxenye zixhunyiwe kuma-conductor wingings kuma-rotor. Oxhumana nabo ababili noma abaningi abathi amabhulashi, enziwe ngomqhubi othambile njengama-graphite, cindezela ukumelana nomqhubi, okwenza ukuslayida ngogesi okuhambisana nezingxenye ezilandelanayo njengoba i-rotor iyaphenduka. Amabhulashi anikela ngokukhetha amanye amanje emaphandleni. Njengoba i-rotor ijikeleza, umzila ukhetha ukuvezwa okuhlukile kanye namanje aqondayo asetshenziswa ekunikezelweni okunikezwayo okunjalo kazibuthe ka-rotor kuhlala kufakwe i-stator futhi kwakha i-torque endaweni eyodwa.

2. I-DC imoto

Ema-motorors angenamkhawulo we-DC, uhlelo lwe-servo lwe-elekthronikhi luthatha indawo oxhumana nabo be-mechanic. Inzwa ye-elekthronikhi ibona i-angle ye-rotor futhi ilawula ukushintshwa kwemishini ye-semiconductor efana nokudluliswa kwama-transistors okushintsha okukhona njengamanje ngama-windings, ama-electromagnets ukuze ama-electromagnets ukuze ama-electromagnets adale i-torque endaweni eyodwa. Ukuqedwa koxhumana naye oslayidi kuvumela ama-motor angenamkhawulo ukuze abe nokuxabana okuncane nokuphila okude; Impilo yabo yokusebenza ikhawulelwe kuphela yimpilo yabo yonke.

I-DC Motors ikhulisa i-torque ephezulu lapho imile, ngokuncipha ngokuqondile, njengokuncipha kwe-velocity kukhuphuka. Ukulinganiselwa okuthile kwama-motor ahlanganisiwe kunganqotshwa ngama-motors angenamkhawulo; Kubandakanya ukusebenza kahle okuphezulu kanye nokuncipha okuphansi kokugqoka kwemishini. Lezi zinzuzo ziza ngezindleko zokungabizi kakhulu, okuyinkimbinkimbi kakhulu, futhi kubiza kakhulu ngo-elekthronikhi.

I-motor evamile engenamabhulazi inama-magren ahlala njalo ajikeleza azungeze i-armature ehleliwe, aqede izinkinga ezihambisana nokuxhuma okuxhumeka kwamanje ku-armature eshukumayo. Isilawuli se-elekhthronikhi sithatha indawo yomhlangano we-commutator wemoto ye-DC egcwele, eshintsha njalo isigaba nama-windings ukuze ugcine ukuguquka kwemoto. Isilawuli senza ukusatshalaliswa kwamandla okwenziwe ngesikhathi okufanayo ngokusebenzisa umjikelezo wombuso oqinile kunokuba kohlelo lwe-commutator.

Ama-motors angenamkhawulo anikela ngezinzuzo eziningana ngaphezulu kwama-DC motors, kufaka phakathi i-torque ephezulu yokulinganisa isisindo, ukuthembeka okwengeziwe ngokuqeda ibhulashi kanye nokuguguleka kwe-commusing, ukuqedwa kwe-ioniking spark kusuka ku
I-Commutator, kanye nokuncishiswa okuphelele kokuphazanyiswa kwe-electromagnetic (EMI). Ngaphandle kokuphikisana noRotor, awekho ngaphansi kwamandla amakhulu, futhi ngenxa yokuthi izindondo zisekelwa yizindlu, zingaphokwa ngokuhunyushwa, kungadingi ukuhamba komoya ngaphakathi kwemoto yokupholisa. Lokhu kusho ukuthi abantu bangaphakathi bemoto bangavalelwa ngokuphelele futhi bavikelekile ekungcoleni noma kwenye inkinga yakwamanye amazwe.

Ukuhamba nge-motorless motor kungaqaliswa ku-software kusetshenziswa i-microcontroller, noma kungahle kube ngenye indlela usebenzisa amasekethe we-analog noma wedijithali. Ukuhamba nge-elekthronikhi esikhundleni samabhulashi kuvumela ukuguquguquka okukhulu kanye namakhono angatholakali nge-DC Motors, kufaka phakathi umkhawulo wejubane, ukusebenza kwe-microstepping kokulawulwa okuhamba kancane nokuhle, kanye ne-horque ebambekayo lapho kumiswa. Isoftware yokulawula ingenziwa ngokwezifiso ku-motor ethile esetshenziswa kuhlelo lokusebenza, okuholela ekusebenzeni kahle kwezikhathi.

Amandla aphezulu angasetshenziswa kwi-motor engenamsebenzi alinganiselwe cishe ngokushisa; [ukucaphuna okudingekayo] Ukushisa okuningana kwenza amandla ama-magnets futhi kuzolimaza ukufakwa kwama-windings.

Lapho uguqula ugesi ube amandla emishini, ama-motor angenamsebenzi asebenza kahle kunama-motor ahlanganisiwe ngokuyinhloko ngenxa yokungabikho kwamabhulashi, anciphisa ukulahleka kwamandla emishini ngenxa yokushayisana. Ukusebenza kahle okuthuthukisiwe kukhulu kakhulu ezindaweni ezingekho umthwalo kanye nezindawo eziphansi zomthwalo wejika lokusebenza kwemoto.

Izindawo nezidingo lapho abakhiqizi basebenzisa khona i-DC Moter-Type DC Motors kufaka phakathi ukusebenza kwamahhala, isivinini esikhulu, kanye nokusebenza lapho kuba yingozi (ie izindawo eziqhumayo) noma kungathinta imishini ebucayi ngokobuchwepheshe.

Ukwakhiwa kwemoto engenabhulazwa kufana nemoto ye-stepper, kepha ama-motors anomehluko obalulekile ngenxa yokwehluka kokusebenza nokusebenza. Ngenkathi ama-motorter motors avama kakhulu nge-rotor endaweni echaziwe, imoto ebhulathele imvamisa ihloselwe ukukhiqiza ukujikeleza okuqhubekayo. Zombili izinhlobo zezimoto zingaba nenzwa ye-rotor isikhundla ngempendulo yangaphakathi. Kokubili i-motor ye-stepper kanye ne-motor eklanywe kahle eklanywe kahle ingabamba i-torque ethambile ku-zero rpm.
