Kev piav qhia ntawm cov kev teeb tsa ntawm lub cev muaj zog stepper (I)

Ib, Tuav lub zog;

Lub zog torque uas yuav tsum tau siv los tig lub cev muaj zog thaum ob theem ntawm cov stepper motor windings raug energized nrog rated DC tam sim no. Lub zog tuav yog me ntsis loj dua li lub zog khiav ntawm qhov ceev qis (qis dua 1200rpm);

2, qhov ntsuas tam sim no;

Qhov tam sim no muaj feem cuam tshuam nrog lub cheeb thiab tus naj npawb ntawm kev tig ntawm lub kauj winding. Feem ntau hais lus, lub zog tuav yog qhov sib npaug rau cov motors sib xws rau tib qhov loj me, tab sis cov yam ntxwv ceev ceev ntawm cov motors nrog cov tam sim no loj yog qhov zoo dua li cov uas muaj cov tam sim no me me;

Lub cev muaj zog inductance;

Inductance kuj yog ib qho tseem ceeb rau stepper motors, sib raug rau tib lub cev muaj zog loj, qhov inductance loj txhais tau tias lub cev muaj zog ntsuas tam sim no me me, thiab lub zog ceev ceev tsis zoo li lub cev muaj zog inductance me me;

Mechanical precision;

rotor nce thiab nqis ob ntu ntawm qhov tseeb ntawm cov hniav tsis raug thiab stator-rotor cua sib npaug ntawm qhov tseeb (qhov zoo tagnrho ntawm qhov sib txawv ntawm ib sab cua 0.04 hli), feem ntau cuam tshuam rau lub cev muaj zog ua haujlwm torque thiab kev ua haujlwm du;

五, Subdivision;

Muaj ob txoj hauv kev los qhia txog kev faib ua pawg 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 kev faib ua pawg;

Kev Hloov Pauv: lub cev muaj zog ob theem (1.8 ° kauj ruam lub kaum sab xis) tsav, piv txwv li, tsis muaj kev faib (1 kev faib), lub 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 tswv yim ntawm tam sim no: lub cev muaj zog ntsuas tam sim no thiab lub zog teeb tsa tsav. Thaum siv, tus tsav teeb tsa tam sim no ≤ lub cev muaj zog ntsuas tam sim no * 1.2, txwv tsis pub, lub cev muaj zog yuav hlawv tawm;

七、 Unipolar thiab bipolar;

Muaj ob lub tswv yim 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、 Signal Inputs;

Muaj ob hom teeb liab nkag: ib qho kawg teeb liab nkag thiab qhov sib txawv teeb liab nkag.

Cov teeb liab ib zaug xwb: 1, qhov zoo sib xws: phim NPN hom maub los; 2, qhov tsis zoo sib xws: phim PNP hom maub los;

Lub teeb liab sib txawv: 1, qhov sib txawv: feem ntau daim npav tswj kev txav mus los; 2, qhov zoo sib xws: lub teeb liab zoo kawg luv; 3, qhov tsis zoo sib xws: lub teeb liab tsis zoo kawg luv.
