Yuav ua li cas cov stepper motors qeeb qeeb?

Cov cav stepperyog cov khoom siv electromechanical uas hloov cov hluav taws xob impulses ncaj qha mus rau hauv kev txav khoom siv. Los ntawm kev tswj cov kab ke, zaus thiab tus lej ntawm cov hluav taws xob impulses siv rau lub cev muaj zog coils, stepper motors tuaj yeem tswj tau rau kev tsav tsheb, ceev thiab lub kaum sab xis ntawm kev tig. Tsis muaj kev pab los ntawm lub kaw lus tswj hwm rov qab kaw nrog qhov chaw sensing, qhov chaw meej thiab kev tswj ceev tuaj yeem ua tiav los ntawm kev siv lub kaw lus tswj hwm qhib yooj yim, pheej yig uas muaj lub cev muaj zog stepper thiab nws tus tsav tsheb nrog.

Stepper motor ua ib qho khoom siv tseem ceeb, yog ib qho khoom tseem ceeb ntawm mechatronics, siv dav hauv ntau yam kev tswj hwm automation. Nrog rau kev txhim kho ntawm microelectronics technology thiab precision manufacturing technology, qhov kev thov rau stepper motors nce ntxiv txhua hnub, thiab stepper motors thiab gear kis mechanism ua ke nrog gearboxes, kuj nyob rau hauv ntau thiab ntau daim ntawv thov scenarios pom, niaj hnub no thiab txhua tus neeg to taub hom gear kis mechanism no.

Yuav ua li cas kom qeeb qeeblub cev muaj zog stepper?

Raws li lub cev muaj zog tsav tsheb uas siv dav thiab siv dav, stepper motor feem ntau siv ua ke nrog cov khoom siv deceleration kom ua tiav qhov kev sib kis zoo tagnrho; thiab cov khoom siv deceleration thiab cov txheej txheem uas siv rau stepper motor yog xws li deceleration gearboxes, encoders, controllers, pulse signals thiab lwm yam.

Lub zog ntawm lub zog pulse deceleration: stepper motor ceev, yog raws li qhov kev hloov pauv ntawm lub zog pulse signal. Hauv kev xav, muab lub zog pulse rau tus tsav tsheb,lub cev muaj zog steppertig lub kaum sab xis (muab faib ua ob ntu). Hauv kev xyaum, yog tias lub teeb liab hloov pauv sai dhau, lub cev muaj zog stepper, vim yog qhov cuam tshuam ntawm lub zog rov qab electromotive sab hauv, qhov sib nqus ntawm lub rotor thiab stator yuav tsis tuaj yeem ua raws li qhov kev hloov pauv ntawm lub teeb liab hluav taws xob, uas yuav ua rau thaiv thiab poob kauj ruam.

Kev txo qis ntawm lub thawv iav txo qis: lub cev muaj zog stepper nruab nrog lub thawv iav txo qis siv ua ke, cov zis ntawm lub cev muaj zog stepper tso zis siab ceev, qhov ceev qis torque, txuas nrog lub thawv iav txo qis, lub thawv iav sab hauv txo cov iav mesh kis tau los ntawm qhov sib piv txo qis, cov zis ntawm lub cev muaj zog stepper ntawm qhov ceev txo qis, thiab txhim kho lub zog kis tau, kom ua tiav qhov zoo tagnrho kis tau zoo; qhov cuam tshuam deceleration nyob ntawm qhov sib piv txo qis ntawm lub thawv iav, qhov loj dua qhov sib piv txo qis, qhov me dua qhov ceev tso zis, thiab vice versa. Qhov cuam tshuam ntawm deceleration nyob ntawm qhov sib piv txo qis ntawm lub thawv iav, qhov loj dua qhov sib piv txo qis, qhov me dua qhov ceev tso zis thiab vice versa.

Kev tswj ceev ntawm cov nkhaus exponential: cov nkhaus exponential, hauv software programming, thawj qhov kev xam ntawm lub sijhawm tas mus li khaws cia rau hauv lub cim xeeb computer, ua haujlwm taw tes rau qhov kev xaiv. Feem ntau, lub sijhawm ua kom nrawm thiab qeeb kom ua tiav lub cev muaj zog stepper yog ntau dua 300ms. Yog tias koj siv lub sijhawm ua kom nrawm thiab qeeb luv dhau, rau feem ntau ntawmcov cav stepper, nws yuav nyuaj rau ua tiav qhov kev sib hloov ceev ntawm lub cev muaj zog stepper.

Kev tswj hwm qeeb qeeb los ntawm encoder: PID tswj, ua ib txoj kev tswj hwm yooj yim thiab siv tau, tau siv dav hauv stepper motor drives. Nws yog raws li tus nqi r (t) thiab tus nqi tso zis tiag tiag c (t) tsim qhov kev tswj hwm sib txawv e (t), qhov sib txawv ntawm qhov sib piv, sib xyaw thiab sib txawv los ntawm kev sib xyaw ua ke ntawm cov khoom tswj hwm, kev tswj hwm khoom tswj hwm. Lub sensor txoj haujlwm sib xyaw ua ke siv rau hauv lub cev muaj zog stepper ob-theem, thiab lub tshuab tswj hwm PI ceev uas kho tau tsis siv neeg tau tsim los ntawm kev ntes txoj haujlwm thiab kev tswj hwm vector, uas tuaj yeem muab cov yam ntxwv zoo nyob rau hauv cov xwm txheej ua haujlwm sib txawv. Raws li tus qauv lej ntawm lub cev muaj zog stepper, lub kaw lus tswj hwm PID ntawm lub cev muaj zog stepper tau tsim, thiab PID tswj hwm algorithm siv los txais cov khoom tswj hwm, kom tswj tau lub cev muaj zog kom txav mus rau qhov chaw teev tseg.

Thaum kawg, qhov kev tswj hwm tau txheeb xyuas los ntawm kev simulation kom muaj cov yam ntxwv teb zoo. Kev siv PID maub los muaj qhov zoo ntawm cov qauv yooj yim, kev ruaj khov, kev ntseeg tau thiab lwm yam, tab sis nws tsis tuaj yeem daws cov ntaub ntawv tsis paub meej hauv lub kaw lus.
