Bayanin sigogin motar stepper (I)

一、Rike ƙarfin juyi;

Ƙarfin da ake buƙata don juya shaft ɗin fitarwa na motar lokacin da aka kunna matakai biyu na naɗewar motar stepper tare da ƙimar wutar lantarki ta DC. Ƙarfin da ke riƙewa ya ɗan fi ƙarfin gudu a ƙananan gudu (ƙasa da 1200rpm);

二, wato ƙimar wutar lantarki;

Wutar lantarki tana da alaƙa da diamita da adadin juyawar na'urar juyawa. Gabaɗaya, ƙarfin riƙewa daidai yake da injinan da suka yi daidai da girman iri ɗaya, amma halayen manyan injinan da ke da babban ƙarfin lantarki sun fi waɗanda ke da ƙaramin ƙarfin lantarki da aka kimanta sosai;

三, inductance;

Inductance kuma muhimmin siga ne ga injinan stepper, wanda ya yi daidai da injin girmansa iri ɗaya, babban inductance yana nufin cewa wutar lantarki da aka kimanta a cikin injin ƙarami ne, kuma ƙarfin juyi mai sauri bai yi kyau kamar ƙaramin injin inductance ba;

Daidaiton Inji;

rotor sama da ƙasa sassa biyu na daidaiton haƙori mara kyau da daidaiton gibin iska tsakanin daidaiton (yanayin da ya dace gibin iska na gefe ɗaya 0.04mm), galibi yana shafar ƙarfin aiki na motar da santsi na aiki;

五, Rarraba;

Akwai hanyoyi guda biyu na bayyana rarrabuwar injinan stepper; N (400, 1000, 5000, 6400, da sauransu), N pulses/juya; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, da sauransu), M substance;

Canzawa: tuƙi mai matakai biyu (kusurwar mataki 1.8 °), misali, babu sashe (ƙasa 1), tuƙi yana karɓar bugun 360 ° / 1.8 ° = bugun 200, injin yana juya da'ira N = 200 * M;.

六、 halin yanzu;

Akwai ra'ayoyi guda biyu na halin yanzu: yanayin wutar lantarki da aka auna a kan injin da kuma yanayin wutar lantarki da aka saita a kan injin. Lokacin amfani da shi, direban yana saita yanayin wutar lantarki ≤ yanayin wutar lantarki da aka auna a kan injin * 1.2, in ba haka ba, injin na iya ƙonewa;

七、 Unipolar da bipolar;

Akwai manyan ra'ayoyi guda biyu game da rashin daidaituwa tsakanin bipolar da rashin daidaituwa:

1, injin: unipolar da bipolar;

2, tuƙi: unipolar da bipolar; unipolar drive zai iya tuƙi kawai da unipolar motor, bipolar drive zai iya tuƙi da bipolar motor; unipolar motor ta amfani da unipolar drive da bipolar drive rabin winding effect iri ɗaya ne;

Shigarwar Sigina;

Akwai nau'ikan shigar sigina guda biyu: shigar sigina mai ƙarewa ɗaya da shigar sigina daban-daban.

Sigina masu iyaka ɗaya: 1, tabbataccen gama gari: daidaita mai sarrafa nau'in NPN; 2, mummunan gama gari: daidaita mai sarrafa nau'in PNP;

Siginar bambanci: 1, bambanci: yawancin katunan sarrafa motsi; 2, tabbatacce na gama gari: ƙarshen tabbatacce na gajarta; 3, mummunan na gama gari: ƙarshen ƙarya na gajarta.
