Bayanin sigogin motsi na stepper (I)

一, Rike karfin juyi;

Ƙunƙarar da ake buƙata don jujjuya mashin fitarwar motar lokacin da matakan biyu na iskar motsin stepper ke ƙarfafa tare da ƙimar halin yanzu na DC. Ƙunƙarar riƙewa ya fi girma fiye da karfin gudu a ƙananan gudu (kasa da 1200rpm);

二, da rated halin yanzu;

Halin halin yanzu yana da alaƙa da diamita da adadin jujjuyawar nada. Gabaɗaya magana, da karfin juyi yana daidai daidai da injinan da suka dace da girman iri ɗaya, amma halaye masu saurin sauri na injina tare da babban ƙimar halin yanzu suna da mahimmanci fiye da waɗanda ke da ƙaramin ƙimar yanzu;

三, inductance;

Inductance kuma shine maɓalli na maɓalli don masu motsi na stepper, daidai da girman girman injin ɗin, babban inductance yana nufin cewa injin ɗin da aka ƙididdige ƙarami ne, kuma ƙarfin ƙarfin sauri mai ƙarfi ba shi da kyau kamar ƙaramin injin inductance;

四, Daidaitaccen injin;

na'ura mai juyi sama da ƙasa sassan biyu na daidaitattun hakori ba daidai ba da ma'auni na rata na iska tsakanin ma'auni (madaidaicin yanayi unilateral iska tazarar 0.04mm), yafi rinjayar motar ta aiki karfin juyi da santsi na aiki;

五, Rarraba;

Akwai hanyoyi guda biyu na bayyana rabe-raben injinan stepper; N (400, 1000, 5000, 6400, da dai sauransu), N bugun jini / juya; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, da dai sauransu), M yanki;

Juyawa: biyu-lokaci motor (1.8 ° mataki kwana) drive, misali, babu subdivision (1 subdivision), da drive yarda 360 ° / 1.8 ° = 200 bugun jini, da mota juya da'irar N = 200 * M ;.

六、 halin yanzu;

Akwai ra'ayoyi guda biyu na halin yanzu: injin da aka ƙididdigewa na yanzu da saiti na yanzu. Lokacin amfani, saitin direba na yanzu ≤ motor rated current * 1.2, in ba haka ba, injin na iya ƙonewa;

七, Unipolar da bipolar;

Akwai ra'ayoyi guda biyu na unipolarity da bipolarity:

1, motor: unipolar da bipolar;

2, tuƙi: unipolar da bipolar; Tuƙi na unipolar zai iya tuka motar unipolar kawai, tuƙin bipolar yana iya tuka motar bipolar da unipolar; Motar unipolar ta yin amfani da tuƙin unipolar da bipolar drive rabin tasirin iska iri ɗaya ne;

八, Abubuwan Shiga Sigina;

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

Sigina masu ƙarewa guda ɗaya: 1, tabbataccen gama gari: mai sarrafa nau'in NPN daidai; 2, na kowa mara kyau: mai kula da nau'in PNP mai dacewa;

Sigina daban-daban: 1, bambanci: yawancin katunan sarrafa motsi; 2, gama gari tabbatacce: sigina tabbatacce ƙarshen gajere; 3, gama gari mara kyau: sigina mara kyau gajere.
