Kev piav qhia ntawm stepper motor tsis (I)

IB, Tuav torque;

Lub torque yuav tsum tau tig lub cev muaj zog tso zis ncej thaum ob theem ntawm stepper motor windings yog energized nrog rated DC tam sim no. Lub zog tuav yog me ntsis ntau dua qhov khiav ntawm lub zog qis (qis dua 1200rpm);

二 , qhov ntsuas tam sim no;

Qhov tam sim no muaj feem xyuam rau txoj kab uas hla thiab tus naj npawb ntawm cov lem ntawm winding coil. Feem ntau hais lus, qhov tuav lub zog yog qhov sib npaug ntawm cov motors sib haum rau tib qhov loj, tab sis cov yam ntxwv siab ceev ntawm cov motors nrog cov ntsuas loj tam sim no zoo dua li cov uas muaj cov ntsuas me me;

Lub cev muaj zog inductance;

Inductance kuj yog ib qho tseem ceeb parameter rau stepper motors, sib xws rau tib lub cev muaj zog, ib tug loj inductance txhais tau hais tias lub cev muaj zog rated tam sim no me me, thiab lub high-ceev torque tsis zoo li ib tug me me inductance lub cev muaj zog;

四 、 Mechanical precision;

rotor nce thiab nqis ob ntu ntawm cov hniav tsis ncaj ncees lawm thiab stator-rotor huab cua sib npaug ntawm qhov tseeb (zoo tagnrho cov xwm txheej unilateral huab cua sib txawv 0.04mm), feem ntau cuam tshuam rau lub cev muaj zog kev ua haujlwm torque thiab smoothness ntawm kev ua haujlwm;

五, Subdivision;

Muaj ob txoj hauv kev ntawm kev nthuav qhia cov subdivision ntawm stepper motors; N (400, 1000, 5000, 6400, thiab lwm yam), N pulses / tig; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, thiab lwm yam), M subdivision;

Conversion: ob-theem lub cev muaj zog (1.8 ° kauj ruam) tsav, piv txwv li, tsis muaj subdivision (1 subdivision), tus tsav txais 360 ° / 1.8 ° = 200 pulses, lub cev muaj zog tig ib lub voj voog N = 200 * M;.

六, tam sim no;

Muaj ob lub ntsiab lus ntawm tam sim no: lub cev muaj zog ntsuas tam sim no thiab tsav teeb tam sim no. Thaum siv, tus tsav tsheb teeb tsa tam sim no ≤ lub cev muaj zog ntsuas tam sim no * 1.2, txwv tsis pub, lub cev muaj zog yuav hlawv;

七 、 Unipolar thiab bipolar;

Muaj ob lub ntsiab lus ntawm unipolarity thiab bipolarity:

1, lub cev muaj zog: unipolar thiab bipolar;

2, tsav: unipolar thiab bipolar; unipolar tsav tsuas yog tsav unipolar lub cev muaj zog, bipolar tsav tuaj yeem tsav bipolar thiab unipolar lub cev muaj zog; unipolar lub cev muaj zog siv unipolar tsav thiab bipolar tsav ib nrab winding nyhuv yog tib yam;

八, Teeb liab inputs;

Muaj ob hom teeb liab tawm tswv yim: ib leeg-kawg teeb liab input thiab sib txawv teeb liab input.

Ib leeg-kawg signals: 1, zoo ib yam: match NPN hom maub los; 2, tsis zoo: phim PNP hom maub los;

Cov teeb liab sib txawv: 1, qhov sib txawv: feem ntau cov ntawv tswj kev txav; 2, pom zoo: teeb liab zoo kawg luv luv; 3, tsis zoo: teeb liab tsis zoo kawg luv luv.
