Yuav ua li cas ntsuas qhov rov qab electromotive quab yuam ntawm tas li hlau nplaum synchronous servo tsav?
Raws li txoj cai ntawm electromagnetics, thaum cov sib txawv ntawm qhov sib txawv, tus neeg ua haujlwm nyob ze yuav tsim kom muaj kev sib txuas lus electromotive uas nws txoj kev coj ua raws li Faraday txoj cai thiab Lenz txoj cai, uas yog qhov fab ntxeev ntawm qhov kev siv hluav taws xob thaum pib. Qhov no voltage yog lub zog electromotive force. Nyob rau hauv cov hlau nplaum sib txuas ua ke, ua ntev li ntev tau lub cav qev, muaj kev sib txuas los ua ib qho kev sib txuas ntawm cov hlau nplaum, thiaj li muaj ib qho hluav taws xob ntawm lub cav hlau. Qhov rov qab electromotive force yog qhia los ntawm E1, thiab nws cov txiaj ntsim zoo yog xam raws li hauv qab no:
ntawm lawv:
KE - yog qhov feem xyuam nrog lub cev;
FN - qhov ntau zaus ntawm tus stator tam sim no;
NL - pes tsawg ntawm kev lem ntawm stator windings ib theem;
f - qhov siab tshaj ntawm qhov loj hauv lub cev.
Ua ntej, tus neeg ntaus sib tua ntawm tus neeg sib tw-electromotive
◆ Rotor angular tshaj tawm
◆ Lub nqus hlau los ntawm cov rotor hlau
◆ Cov xov tooj cua ntawm tus qauv
Thaum lub tshuab tsim, lub rotor magnetic field thiab tus naj npawb ntawm cov stator winding yog txiav txim siab. Vim li no, qhov tsuas yog txiav txim rau lub zog ntawm sab nraum electromotive yog qhov rotor angular tshaj tawm, los yog rotor ceev. Raws li lub rotor ceev nce, sab nraum electromotive quab yuam kuj nce.
Qhov ob, txoj kev xeem EMF rov qab
Raws li cov kev cai ntawm kev lag luam ntawm cov hlau nplaum hluav taws xob AC servo motor, peb feem ntau siv lub nraub qaum electromotive force tas mus li soj ntsuam lub qhov hluav taws xob ntawm lub tshuab synchronous. Lub sab EMF tas li yog ib qho tseem ceeb heev ntawm qhov kev ntsuas ntawm lub tshuab synchronous, uas yog cuam tshuam rau kev sib tw khiav ntawm lub cav thiab tsim ntawm tus tswj. Vim li no, nyob rau ntawm cov khoom siv hluav taws xob hauv lub tshuab synchronous, qhov parameter no yuav tsum raug kuaj kom raug, thiab txoj kev xeem yog siv los tshawb xyuas seb puas tsim cov khoom tsim nyog raws li kev cai.
GB / T50349 daim npliag lub npe AC servo lub cev muaj peev xwm ua rau pom tias kev tsav tsheb yuav tsum tau sim ua ntej mus rau ib qho kev khiav ceev uas tau teev los ntawm cov xwm txheej, thiab ces cov ntawv yauv tau pom nrog lub oscilloscope, thiab lub zog ntawm sab nraum electromotive ) yog xam los ntawm qhov ntsuas thiab qhov ceev. Thiab yuav tsum tau Ke kom tau raws li qhov kev xav tau ntawm kev ua lag luam tas mus li synchronous servo motor.
Daim duab 1: Rov qab EMF Test Platform
Raws li pom hauv daim duab saum toj no, lub tshuab hluav taws xob nyob rau sab saum toj, daim hlau qaum electromotive force test platform, raws li kev kuaj raws li kev cai, kev tsav lub cev yog siv rau hluav taws xob, thiab tsav tsav yog tsav mus rau khiav tsis khiav ceev mus rau n; tus ceev sensor yog siv los ua kom tiav qhov kev xeem ceev, WP4000 kuj sib txawv thiab zaus ntsuas fais fab Lub cav kuaj kab rov qab EMF U kuaj tiav.
Thaum kuaj, kab rov qab electromotive force U thaum lub cav tsis muaj qhov ntsuas ceev n ntsuas, thiab rov qab electromotive yuam qhov tas yog xam los ntawm cov qauv hauv qab no los xyuas seb puas yuav tsum tau ua raws li qhov kev xav tau.
Hauv cov mis:
Ke - sab nraum electromotive quab yuam nyob rau hauv lub hauv siab ib ntus thiab rho tawm ib ob (V / rad * -1 ^ s);
U - sab nraud electromotive quab yuam ntawm lub voj kab, chav tsev yog volt (V), tus nqi zoo ntawm txoj kab rov qab electromotive quab yuam ntawm sine wave tsav, thiab rov qab electromotive force amplitude ntawm cov square wave tsav lub cev;
N - qhov kev ntsuas ntawm ntsuas qhov ntsuas, lub tsev yog lub kiv puag ncig ib feeb (r / min).
No lub tswv yim xaiv WP4000 kuj sib txawv ntawm qhov fais fab kev lag luam kom tiav cov nraub qaum electromotive force thiab kev xeem ceev, thiab saws cov lus zoo synchronization los xyuas kom meej cov synchronous kuaj ntawm hluav taws xob tsis thiab tsis-point tsis. Tib lub sijhawm, WP4000 tus cwjpwm sib txawv ntawm qhov ntsuas zog qhib qhov chaw nres tsheb yuavtsum tau qhib, thiab cov ntaubntawv ntawm cov ntaubntawv ntiag tug ntawm cov ntaub ntawv coj tuaj yeem ncaj qha mus koom nrog lub host computer los ntawm Ethernet, uas tuaj yeem hloov tau cov kev oscilloscope. Qhov rov qab electromotive yuam kev tas mus kuaj tau ncaj qha los ntawm cov kev cai ntsuam xyuas software, uas yog txaus siab rau qhov kev kuaj tsis siv neeg txoj cai ntawm kev pabcuam hauv lub cav servo.
