C. Maye gurbin motar da ƙaramin kusurwar mataki, kamar motar matakai uku ko biyar;
D. Canja zuwa injinan AC servo, waɗanda kusan za su iya shawo kan girgiza da hayaniya gaba ɗaya, amma a farashi mai tsada;
E. A cikin shaft ɗin motar da ke da damper mai maganadisu, kasuwa tana da irin waɗannan samfuran, amma tsarin injina na babban canji.
10. Shin rarrabawar drive ɗin yana wakiltar daidaito?
Haɗin motar Stepper a zahiri fasaha ce ta damping ta lantarki (don Allah a duba littattafan da suka dace), babban manufarta ita ce rage ko kawar da girgizar ƙasa ta motar stepper, kuma inganta daidaiton gudu na motar aiki ne kawai na fasahar haɗa hanyoyin. Misali, ga motar hawa mai matakai biyu masu haɗa hanyoyin tare da kusurwar matakai na 1.8°, idan an saita lambar haɗa hanyoyin direban interpolation zuwa 4, to ƙudurin gudu na motar shine 0.45° a kowace bugun jini. Ko daidaiton motar zai iya kaiwa ko kusantowa 0.45° shi ma ya dogara da wasu abubuwa kamar daidaiton ikon sarrafa halin yanzu na haɗa hanyoyin. Masana'antun daban-daban na daidaiton hanya na rarraba hanyoyin na iya bambanta sosai; mafi girman wuraren da aka raba suna da wahalar sarrafa daidaito.
11. Menene bambanci tsakanin haɗin jeri da haɗin layi ɗaya na motar matakai huɗu ta haɗin gwiwa da direba?
Motar matattakalar matakai huɗu gabaɗaya ana tuƙa ta ta hanyar direba mai matakai biyu, saboda haka, ana iya amfani da haɗin a cikin hanyar haɗi mai jere ko layi ɗaya don haɗa motar mai matakai huɗu zuwa amfani da matakai biyu. Ana amfani da hanyar haɗin jerin a lokutan da saurin motar yake da girma, kuma fitowar wutar direban da ake buƙata shine sau 0.7 na ƙarfin motar, don haka dumama motar ƙarami ne; ana amfani da hanyar haɗin layi ɗaya gabaɗaya a lokutan da saurin motar yake da girma (wanda kuma aka sani da hanyar haɗin sauri mai girma), kuma fitowar wutar direban da ake buƙata shine sau 1.4 na ƙarfin motar, don haka dumama motar yana da girma.
12. Yadda ake tantance ƙarfin wutar lantarki na DC na direban motar stepper?
A. Ƙayyade ƙarfin lantarki
Wutar lantarki ta direban motar stepper mai haɗaka gabaɗaya tana da faɗi sosai (kamar ƙarfin wutar lantarki na IM483 na 12 ~ 48VDC), yawanci ana zaɓar ƙarfin wutar lantarki bisa ga saurin aiki na motar da buƙatun amsawa. Idan saurin aikin motar yana da girma ko buƙatar amsawa tana da sauri, to ƙimar ƙarfin lantarki ma tana da yawa, amma kula da ripple na ƙarfin wutar lantarki ba zai iya wuce matsakaicin ƙarfin shigarwa na direban ba, in ba haka ba direban na iya lalacewa.
B. Tantance halin yanzu
Gabaɗaya ana ƙayyade wutar lantarki bisa ga yanayin fitarwa na I na direba. Idan ana amfani da wutar lantarki mai layi, wutar lantarki na iya zama sau 1.1 zuwa 1.3 na I. Idan ana amfani da wutar lantarki mai sauyawa, wutar lantarki na iya zama sau 1.5 zuwa 2.0 na I.
13. A waɗanne yanayi ne siginar da ba ta aiki a intanet ba KYAUTA ce daga direban motar da ke amfani da ita a kan matakan hawa?
Idan siginar da ba ta aiki ba KYAUTA ta yi ƙasa, ana yanke fitarwa daga direba zuwa motar kuma na'urar juyawar motar tana cikin yanayi na kyauta (yanayin offline). A wasu kayan aikin sarrafa kansa, idan ana buƙatar juya shaft ɗin motar kai tsaye (da hannu) lokacin da tuƙin ba ya aiki, za ka iya saita siginar KYAUTA ta yi ƙasa don ɗaukar motar ba tare da aiki ba kuma ka yi aiki da hannu ko daidaitawa. Bayan an kammala aikin hannu, sake saita siginar KYAUTA ta yi sama don ci gaba da sarrafawa ta atomatik.
14. Menene hanya mai sauƙi ta daidaita alkiblar juyawar injin matakala mai matakai biyu idan aka kunna shi?
Kawai daidaita A+ da A- (ko B+ da B-) na wayoyin mota da direba.
15. Menene bambanci tsakanin injinan stepper masu matakai biyu da na matakai biyar masu haɗin gwiwa don aikace-aikace?
Amsar Tambaya:
Gabaɗaya dai, injinan matakai biyu masu manyan kusurwoyi suna da kyawawan halaye na babban gudu, amma akwai yankin girgiza mai ƙarancin gudu. Injinan matakai biyar suna da ƙaramin kusurwar matakai kuma suna aiki cikin sauƙi a ƙananan gudu. Saboda haka, a cikin aikin motar, buƙatun daidaiton gudu suna da yawa, kuma galibi a cikin sashin ƙananan gudu (galibi ƙasa da rpm 600) ya kamata a yi amfani da injin matakai biyar; akasin haka, idan ana neman aikin injin mai sauri, ya kamata a zaɓi daidaito da santsi na lokacin ba tare da buƙatu da yawa ba a farashi mai rahusa na injinan matakai biyu. Bugu da ƙari, ƙarfin injinan matakai biyar yawanci ya fi 2NM, don ƙananan aikace-aikacen ƙarfin juyi, ana amfani da injinan matakai biyu gabaɗaya, yayin da za a iya magance matsalar santsi mai ƙarancin gudu ta amfani da tuƙi mai rabawa.
