Motar zafin da aka ba da izinin zuwa nawa, yafi dogara da matakin rufewar ciki na motar. Ayyukan rufewa na ciki a babban yanayin zafi (digiri 130 ko fiye) kafin a lalace. Don haka idan dai na ciki bai wuce digiri 130 ba, motar ba za ta rasa zobe ba, kuma yanayin zafin jiki zai kasance ƙasa da digiri 90 a wannan lokacin.

Saboda haka, stepper motor surface zafin jiki a 70-80 digiri ne na al'ada. Hanyar ma'aunin zafin jiki mai sauƙi mai amfani da ma'aunin zafi da sanyio, Hakanan zaka iya tantancewa: tare da hannu na iya taɓa fiye da 1-2 seconds, ba fiye da digiri 60 ba; tare da hannu zai iya taɓawa kawai, kimanin digiri 70-80; 'yan saukad da ruwa da sauri sun haura, ya fi digiri 90.

3, stepper motordumama tare da saurin canje-canje.

Lokacin amfani da m halin yanzu drive fasaha, stepper Motors a tsaye da kuma low gudun, na yanzu zai kasance akai don kula da akai karfin juyi fitarwa. Lokacin da saurin ya yi girma zuwa wani matakin, yuwuwar injin na ciki na motar ya tashi, na yanzu zai ragu a hankali, kuma karfin juyi shima zai ragu.

Sabili da haka, yanayin dumama saboda asarar jan karfe zai dogara da sauri. A tsaye da ƙananan gudu gabaɗaya suna haifar da zafi mai ƙarfi, yayin da babban gudu ke haifar da ƙarancin zafi. Amma asarar baƙin ƙarfe (ko da yake ƙananan ƙananan) canje-canje ba ɗaya ba ne, kuma motar a matsayin duka zafi shine jimlar biyun, don haka abin da ke sama shine kawai halin da ake ciki.

4, tasirin zafi.

Kodayake zafin motar gabaɗaya baya shafar rayuwar motar, yawancin abokan ciniki basa buƙatar kula da su. Amma da gaske zai kawo wani mummunan tasiri. Kamar nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan haɓakar thermal na ɓangarorin ciki na motar suna haifar da canje-canje a cikin damuwa na tsari da ƙananan canje-canje a cikin tazarar iska na ciki, zai shafi tasirin motsin motsi, saurin sauri zai zama mai sauƙin rasa mataki. Wani misali kuma shi ne cewa wasu lokuta ba sa barin zafin da ya wuce kima na motar, kamar kayan aikin likitanci da na'urorin gwaji masu inganci, da dai sauransu. Don haka, zafin motar ya zama dole don sarrafawa.

5, yadda ake rage zafin injin.

Rage samar da zafi, shine don rage asarar tagulla da asarar ƙarfe. Rage asarar jan ƙarfe a cikin kwatance guda biyu, rage juriya da halin yanzu, wanda ke buƙatar zaɓin ƙaramin juriya da ƙimar halin yanzu na injin gwargwadon yuwuwar, injin mai hawa biyu, ana iya amfani da injin a cikin jerin ba tare da injin daidaici ba. Amma wannan sau da yawa ya saba wa bukatun juzu'i da babban gudu. Don injin da aka zaɓa, aikin sarrafa rabin-lokaci na tuƙi da aikin layi ya kamata a yi amfani da shi gabaɗaya, tsohon yana rage halin yanzu lokacin da motar ke hutawa, kuma na ƙarshen kawai ya yanke na yanzu.

Bugu da kari, da subdivision drive, saboda halin yanzu waveform yana kusa da sinusoidal, m harmonics, motor dumama kuma zai zama kasa. Akwai 'yan hanyoyi don rage asarar ƙarfe, kuma matakin ƙarfin lantarki yana da alaƙa da shi. Ko da yake motar da ke motsawa ta babban ƙarfin lantarki zai haifar da karuwa a cikin halaye masu sauri, kuma yana kawo haɓakar haɓakar zafi. Don haka ya kamata mu zaɓi matakin ƙarfin wutar lantarki mai dacewa, la'akari da saurin gudu, santsi da zafi, hayaniya da sauran alamomi.

Dabarun sarrafawa don haɓakawa da tafiyar matakai na matakan motsi na stepper.

Tare da tartsatsi amfani da stepper Motors, nazarin stepper motor iko kuma yana karuwa, a cikin farawa ko hanzari idan stepper bugun jini canje-canje da sauri, da na'ura mai juyi saboda inertia kuma ba biye da lantarki siginar canje-canje, sakamakon toshe ko rasa mataki a cikin tasha ko ragewa saboda wannan dalili na iya haifar da overstepping. Don hana toshewa, asarar mataki da overshoot, inganta mitar aiki, motar motsa jiki don ɗaga saurin gudu.

Gudun motar stepper ya dogara da mitar bugun jini, adadin haƙoran rotor da adadin bugun. Gudun sa na kusurwa ya yi daidai da mitar bugun bugun jini kuma yana aiki tare cikin lokaci tare da bugun jini. Don haka, idan adadin haƙoran rotor da adadin bugun bugun ya tabbata, ana iya samun saurin da ake so ta hanyar sarrafa mitar bugun jini. Tun da stepper mota aka fara tare da taimakon synchronous karfin juyi, da farawa mita ba high domin kada a rasa mataki. Musamman yayin da ƙarfin ya karu, diamita na rotor yana ƙaruwa, rashin ƙarfi yana ƙaruwa, kuma mitar farawa da matsakaicin matsakaicin gudu na iya bambanta da kusan sau goma.

Halayen mitar farawa na motar stepper ta yadda matakin matakin ba zai iya kai tsaye kai tsaye zuwa mitar aiki ba, amma don samun tsarin farawa, wato, daga ƙananan saurin gudu a hankali har zuwa saurin aiki. Tsaya lokacin da ba za a iya rage mitar aiki nan da nan zuwa sifili ba, amma don samun raguwar saurin sauri a hankali zuwa tsarin sifili.

 

Matsakaicin fitarwa na injin stepper yana raguwa tare da haɓakar mitar bugun jini, mafi girman saurin farawa, ƙaramin ƙarfin farawa, mafi ƙarancin ikon fitar da kaya, farawa zai haifar da asarar mataki, kuma a cikin tasha zai faru lokacin da overshoot. Don sanya injin stepper da sauri ya kai ga saurin da ake buƙata kuma kada ya rasa mataki ko overshoot, maɓalli shine don aiwatar da tsarin haɓakawa, ƙarfin haɓakar da ake buƙata don yin cikakken amfani da juzu'in da injin stepper ke bayarwa a kowane mitar aiki, kuma kada ya wuce wannan jujjuyawar. Sabili da haka, aikin stepper motor gabaɗaya dole ne ya shiga cikin hanzari, saurin uniform, raguwar matakai uku, lokacin haɓakawa da raguwar lokaci a matsayin ɗan gajeren lokaci, tsayin lokaci mai tsayi muddin zai yiwu. Musamman a cikin aikin da ake buƙatar amsawa mai sauri, daga farawa zuwa ƙarshen lokacin gudu da ake buƙata don zama mafi guntu, wanda dole ne ya buƙaci hanzari, tsarin ƙaddamarwa shine mafi ƙanƙanta, yayin da mafi girman gudu a cikin sauri.
