Ka'idar samar da zafimotar stepper.

 

 

1, yawanci ana ganin dukkan nau'ikan injina, na ciki sune tsakiyar ƙarfe da kuma na'urar jujjuyawa.Na'urar juyawa tana da juriya, tana da kuzari, za ta haifar da asara, girman asarar ya yi daidai da murabba'in juriya da halin yanzu, wanda galibi ana kiransa asarar jan ƙarfe, idan halin yanzu ba DC ko sine wave ba ne na yau da kullun, zai kuma haifar da asarar harmonic; tsakiya yana da tasirin hysteresis eddy current, a cikin filin maganadisu mai canzawa zai kuma haifar da asara, girmansa da kayansa, halin yanzu, mita, ƙarfin lantarki, wanda ake kira asarar ƙarfe. Asarar jan ƙarfe da asarar ƙarfe za su bayyana a cikin nau'in zafi, don haka yana shafar ingancin motar. Motocin stepper gabaɗaya suna bin daidaiton matsayi da fitarwa na karfin juyi, inganci yana da ƙarancin inganci, yanayin gaba ɗaya yana da girma sosai, kuma manyan abubuwan haɗin gwiwa, mitar canjin halin yanzu kuma ya bambanta da saurin, don haka injinan stepper gabaɗaya suna da zafi, kuma yanayin ya fi tsanani fiye da motar AC gabaɗaya.

2, kewayon da ya dacemotar stepperzafi.

Zafin da aka yarda da shi a cikin mota ya dogara ne da matakin rufin cikin motar. Aikin rufin cikin gida a yanayin zafi mai yawa (digiri 130 ko fiye) kafin a lalata shi. Don haka matuƙar zafin cikin bai wuce digiri 130 ba, injin ba zai rasa zoben ba, kuma zafin saman zai kasance ƙasa da digiri 90 a wannan lokacin.

Saboda haka, zafin saman motar stepper a digiri 70-80 abu ne na yau da kullun. Ma'aunin zafi mai sauƙi yana da amfani ta hanyar amfani da ma'aunin zafi mai mahimmanci, zaku iya tantancewa kusan: da hannu zai iya taɓawa fiye da daƙiƙa 1-2, ba fiye da digiri 60 ba; da hannu zai iya taɓawa kawai, kimanin digiri 70-80; ɗigon ruwa kaɗan ya tashi da sauri, ya fi digiri 90.

3, motar stepperdumama tare da canje-canjen gudu.

Idan ana amfani da fasahar tuƙi ta wutar lantarki mai ɗorewa, injinan stepper a tsaye da ƙarancin gudu, wutar za ta kasance mai ɗorewa don kiyaye fitowar wutar lantarki mai ɗorewa. Idan gudun ya yi yawa zuwa wani mataki, ƙarfin wutar lantarki na cikin motar yana ƙaruwa, wutar za ta ragu a hankali, kuma ƙarfin wutar ma zai ragu.

Saboda haka, yanayin dumama da asarar jan ƙarfe ke haifarwa zai dogara ne da gudu. Saurin da ba ya canzawa da kuma saurin da ba ya canzawa gaba ɗaya yana haifar da zafi mai yawa, yayin da babban gudu ke haifar da ƙarancin zafi. Amma canje-canjen asarar ƙarfe (kodayake ƙaramin rabo) ba iri ɗaya bane, kuma injin gaba ɗaya shine jimlar zafi biyu, don haka abin da ke sama shine yanayin gabaɗaya kawai.

4, tasirin zafi.

Duk da cewa zafin motar ba ya shafar rayuwar motar, yawancin abokan ciniki ba sa buƙatar kulawa da shi. Amma da gaske zai haifar da mummunan tasiri. Kamar bambancin ma'aunin faɗaɗa zafi na sassan ciki na motar yana haifar da canje-canje a cikin damuwa na tsari da ƙananan canje-canje a cikin gibin iska na ciki, zai shafi amsawar motsi na motar, saurin gudu zai zama mai sauƙin rasa mataki. Wani misali kuma shine cewa wasu lokutan ba sa barin zafi mai yawa na motar, kamar kayan aikin likita da kayan aikin gwaji masu inganci, da sauransu. Saboda haka, zafin motar ya kamata ya zama dole don sarrafawa.

5, yadda ake rage zafin injin.

Rage samar da zafi, shine rage asarar jan ƙarfe da asarar ƙarfe. Rage asarar jan ƙarfe ta hanyoyi biyu, rage juriya da halin yanzu, wanda ke buƙatar zaɓar ƙaramin juriya da ƙimar halin yanzu na motar gwargwadon iko, injin mai matakai biyu, ana iya amfani da injin a jere ba tare da injin layi ɗaya ba. Amma wannan sau da yawa ya saba wa buƙatun ƙarfin juyi da babban gudu. Ga injin da aka zaɓa, ya kamata a yi amfani da aikin sarrafa rabin halin yanzu ta atomatik na tuƙi da aikin da ba na layi ba gaba ɗaya, na farko yana rage halin yanzu ta atomatik lokacin da injin ya huta, kuma na biyun kawai yana yanke halin yanzu.

Bugu da ƙari, tuƙi na ɓangaren, saboda yanayin raƙuman ruwa na yanzu yana kusa da sinusoidal, ƙarancin harmonics, dumamar mota shi ma zai yi ƙasa. Akwai hanyoyi kaɗan don rage asarar ƙarfe, kuma matakin ƙarfin lantarki yana da alaƙa da shi. Kodayake motar da babban ƙarfin lantarki ke tuƙawa zai kawo ƙaruwa a cikin halayen saurin gudu, yana kuma kawo ƙaruwa a samar da zafi. Don haka ya kamata mu zaɓi matakin ƙarfin lantarki na tuƙi da ya dace, la'akari da babban gudu, santsi da zafi, hayaniya da sauran alamu.

Dabaru na sarrafawa don hanzartawa da rage gudu na injunan stepper.

Tare da yawan amfani da injinan stepper, nazarin sarrafa motar stepper yana ƙaruwa, a farkon ko hanzari idan bugun stepper ya canza da sauri, na'urar juyawa saboda rashin aiki da kuma rashin bin siginar lantarki, wanda ke haifar da toshewa ko ɓacewar mataki a tasha ko raguwar gudu saboda wannan dalili na iya haifar da wuce gona da iri. Domin hana toshewa, asarar matakai da wuce gona da iri, inganta mitar aiki, injin stepper don ɗaga ikon sarrafa gudu.

Saurin motar stepper ya dogara ne da mitar bugun jini, adadin haƙoran rotor da adadin bugun. Saurin kusurwarsa yana daidai da mitar bugun jini kuma ana daidaita shi cikin lokaci tare da bugun jini. Don haka, idan adadin haƙoran rotor da adadin bugun gudu sun tabbata, ana iya samun saurin da ake so ta hanyar sarrafa mitar bugun jini. Tunda an fara motar stepper tare da taimakon ƙarfinsa na synchronous, mitar farawa ba ta da yawa don kada ta rasa mataki. Musamman yayin da ƙarfin ya ƙaru, diamita na rotor yana ƙaruwa, inertia yana ƙaruwa, kuma mitar farawa da matsakaicin mitar gudu na iya bambanta da sau goma.

Halayen mitocin farawa na motar stepper ta yadda injin stepper ba zai iya kaiwa ga mitocin aiki kai tsaye ba, amma don samun tsarin farawa, wato, daga ƙaramin gudu a hankali ya tashi zuwa saurin aiki. Tsaya lokacin da mitar aiki ba za a iya rage ta nan da nan zuwa sifili ba, amma don samun raguwar saurin gudu a hankali zuwa sifili.

 

Karfin fitarwa na motar stepper yana raguwa tare da ƙaruwar mitar bugun jini, mafi girman mitar farawa, ƙaramar ƙarfin farawa, ƙarancin ikon tuƙa kaya, farawa zai haifar da asarar mataki, kuma a cikin tasha zai faru lokacin da overshoot. Don sa motar stepper ta isa saurin da ake buƙata da sauri kuma kada ta rasa mataki ko overshoot, mabuɗin shine a yi tsarin hanzartawa, ƙarfin hanzarin da ake buƙata don yin cikakken amfani da ƙarfin juyawar da motar stepper ke bayarwa a kowane mitar aiki, kuma kada ta wuce wannan karfin juyi. Saboda haka, aikin motar stepper gabaɗaya dole ne ya bi ta cikin hanzari, gudu iri ɗaya, raguwa matakai uku, lokacin hanzartawa da raguwar lokaci ya zama gajere gwargwadon iko, tsawon lokacin gudu mai ɗorewa gwargwadon iko. Musamman a cikin aikin da ke buƙatar amsawa cikin sauri, daga wurin farawa zuwa ƙarshen lokacin gudu da ake buƙata ya zama mafi guntu, wanda dole ne ya buƙaci haɓakawa, tsarin rage gudu shine mafi guntu, yayin da mafi girman gudu a saurin gudu mai ɗorewa.

 

Masana kimiyya da masu fasaha a gida da waje sun gudanar da bincike mai yawa kan fasahar sarrafa gudu na injinan stepper, kuma sun kafa nau'ikan samfuran lissafi na sarrafa hanzari da rage gudu, kamar samfurin exponential, samfurin layi, da sauransu, kuma bisa ga wannan ƙira da haɓaka nau'ikan da'irori na sarrafawa don inganta halayen motsi na injinan stepper, don haɓaka kewayon aikace-aikacen injinan stepper, haɓaka haɓakawa da rage gudu yana la'akari da halayen lokaci-mita na injinan stepper, duka don tabbatar da cewa injin stepper yana motsi ba tare da rasa mataki ba, amma kuma yana ba da cikakken wasa ga halayen injin, rage lokacin gudu, amma saboda canje-canje a cikin nauyin mota, yana da wuya a cimma yayin da haɓaka gudu da rage gudu ke la'akari da injin kawai a cikin kewayon ƙarfin kaya na saurin kusurwa da bugun jini daidai da wannan alaƙa, ba saboda canje-canje a cikin ƙarfin lantarki, yanayin kaya da halayen canjin ba, wannan hanyar haɓaka gudu tana dawwama, rashin amfani shine ba ta yi la'akari da cikakken ƙarfin fitarwa na injin stepper ba Tare da halayen canjin gudu, injin stepper a babban gudu zai faru ba tare da mataki ba.
