Kufotokozera za magawo a motor stepper (I)

一、Kugwira torque;

Ma torque amafunikira kuti azungulire shaft yotulutsa ma motor pomwe magawo awiri a ma stepper motor windings apatsidwa mphamvu ndi DC yapano. The torque yogwira ndi yayikulu pang'ono kuposa torque yothamanga pa liwiro lotsika (pansi pa 1200rpm);

二、 oveteredwa panopa;

Zamakono zimagwirizana ndi kukula kwake ndi kuchuluka kwa matembenuzidwe a koyilo yokhotakhota. Nthawi zambiri, torque yogwirizira imakhala yofanana ndi ma mota omwe amafanana ndi kukula kwake, koma mawonekedwe othamanga kwambiri amagetsi okhala ndi zida zazikulu zamakono ndizabwinoko kuposa omwe ali ndi zida zazing'ono;

三, inductance;

Inductance ndiyenso gawo lofunikira la ma stepper motors, ofanana ndi kukula kwa injini, inductance yayikulu imatanthawuza kuti mota yomwe idavotera pano ndi yaying'ono, ndipo torque yothamanga kwambiri siili bwino ngati mota yaing'ono yolowera;

四、Kulondola kwamakina;

rotor mmwamba ndi pansi zigawo ziwiri za mwatsatanetsatane dzino lolakwika ndi stator-rotor mpweya kusiyana bwino pakati mwatsatanetsatane (zabwino zinthu unilateral mpweya kusiyana 0.04mm), makamaka zimakhudza galimoto ntchito makokedwe ndi kusalala ntchito;

五、 Kugawikana;

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

Kutembenuka: awiri gawo galimoto (1.8 ° sitepe ngodya) galimoto, mwachitsanzo, palibe kugawa (1 kugawa), galimoto amavomereza 360 ° / 1.8 ° = 200 pulses, galimoto kutembenukira bwalo N = 200 * M;.

六, panopa;

Pali malingaliro awiri apano: motor ovotera panopa ndi drive set panopa. Pamene mukugwiritsa ntchito, dalaivala akukhazikitsa panopa ≤ motor ovotera panopa * 1.2, apo ayi, galimoto akhoza kuwotcha;

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 galimoto ya unipolar, bipolar drive imatha kuyendetsa galimoto ya bipolar ndi unipolar; unipolar galimoto ntchito unipolar pagalimoto ndi bipolar pagalimoto theka mapiringidzo zotsatira ndi chimodzimodzi;

八, Zolowetsa Zizindikiro;

Pali mitundu iwiri ya kulowetsa ma siginecha: kulowetsa siginecha yokhala ndi mbali imodzi ndi kuyika kwa ma siginecha osiyana.

Zizindikiro zokhala ndi malekezero amodzi: 1, zabwino zodziwika bwino: mafananidwe owongolera amtundu wa NPN; 2, zoipa wamba: machesi PNP wolamulira mtundu;

Chizindikiro chosiyana: 1, kusiyanitsa: makhadi ambiri owongolera; 2, wamba zabwino: chizindikiro chabwino mapeto lalifupi; 3, zoipa wamba: chizindikiro zoipa mapeto lalifupi.
