Kufotokozera kwa magawo a injini ya stepper (I)

一、Kugwira mphamvu;

Mphamvu yofunikira pozungulira shaft yotulutsa injini pamene magawo awiri a ma stepper motor windings apatsidwa mphamvu ndi mphamvu ya DC current yovomelezedwa. Mphamvu yogwira ntchito ndi yayikulu pang'ono kuposa mphamvu yothamanga pa liwiro lotsika (pansi pa 1200rpm);

二、 panopa yovotera;

Mphamvu yamagetsi imakhudzana ndi kukula ndi kuchuluka kwa ma current a winding coil. Kawirikawiri, mphamvu yamagetsi yogwirira ntchito imakhala yofanana ndi ya ma motors ofanana ndi kukula komweko, koma makhalidwe a liwiro lamagetsi a ma motors okhala ndi mphamvu yamagetsi yayikulu ndi abwino kwambiri kuposa omwe ali ndi mphamvu yamagetsi yaying'ono;

三, inductance;

Kulowetsa mphamvu ndi gawo lofunika kwambiri la ma stepper motors, omwe ali ndi kukula komweko, kulowetsa mphamvu kwakukulu kumatanthauza kuti mphamvu yamagetsi ya injini ndi yaying'ono, ndipo mphamvu yamagetsi yothamanga kwambiri si yabwino ngati injini yaying'ono yolowetsa mphamvu;

四、Kulondola kwa makina;

rotor mmwamba ndi pansi magawo awiri a kulondola kwa dzino kolakwika ndi kusiyana kwa mpweya pakati pa stator ndi rotor pakati pa kulondola (mikhalidwe yabwino kusiyana kwa mpweya umodzi 0.04mm), makamaka zimakhudza mphamvu yogwirira ntchito ya injini ndi kusalala kwa ntchito;

五、 Kugawikana;

Pali njira ziwiri zofotokozera kugawa kwa ma stepper motors; N (400, 1000, 5000, 6400, etc.), N pulses/turn; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, etc.), M subdivision;

Kutembenuka: galimoto yamagetsi ya magawo awiri (1.8 ° sitepe ngodya), mwachitsanzo, palibe kugawa magawo (kugawa magawo 1), galimotoyo imalandira ma pulses 360 ° / 1.8 ° = 200, galimotoyo imazungulira bwalo N = 200 * M;.

六, panopa;

Pali malingaliro awiri a mphamvu yamagetsi: mphamvu yamagetsi yoyesedwa ndi injini ndi mphamvu yamagetsi yoyikidwa ndi drive. Mukamagwiritsa ntchito, dalaivala akukhazikitsa mphamvu yamagetsi ≤ mphamvu yamagetsi yoyesedwa ndi injini * 1.2, apo ayi, injiniyo ikhoza kuzima;

七、 Unipolar ndi bipolar;

Pali malingaliro awiri a unipolarity ndi bipolarity:

1, mota: unipolar ndi bipolar;

2, kuyendetsa: unipolar ndi bipolar; unipolar drive imatha kuyendetsa unipolar motor yokha, bipolar drive imatha kuyendetsa bipolar ndi unipolar motor; unipolar motor pogwiritsa ntchito unipolar drive ndi bipolar drive theka la kuzungulira ndi chimodzimodzi;

Zolowetsa za Signal;

Pali mitundu iwiri ya ma input a signal: single-end signal input ndi differential signal input.

Zizindikiro zokhala ndi malire amodzi: 1, zabwino zomwe zimafanana: chowongolera cha mtundu wa NPN; 2, zoyipa zomwe zimafanana: chowongolera cha mtundu wa PNP chofanana;

Chizindikiro chosiyanitsa: 1, chosiyana: makadi ambiri owongolera mayendedwe; 2, chodziwika bwino: chizindikiro chabwino kumapeto; 3, chodziwika bwino: chizindikiro choipa kumapeto.
