Hauv cov txheej txheem tswj nruj, sib nqus hmoov brakes tau siv dav vim lawv qhov me me, lub teeb yuag, tsis muaj zog excitation, thiab cov yam ntxwv zoo heev. Kev sib raug zoo ntawm lub zog torque thiab excitation tam sim no ntawm cov hlau nplaum hmoov nres feem ntau hu ua nws cov yam ntxwv zoo li qub. Nws yog qhov kev sib raug zoo ntawm qhov excitation tam sim no thiab tso zis torque ntawm cov hlau nplaum hmoov nres thaum tsav tsheb kawg muaj qhov kev sib hloov tsis tu ncua (n) thiab qhov kawg tsav yog braking.
Lub torque nkhaus ntawm lub sib nqus hmoov nres tuaj yeem muab faib ua peb ntu: ntu nonlinear, ntu ntu, thiab ntu saturation. Sib nqus hmoov brakes muaj cov yam ntxwv zoo tas li, thiab qhov tso zis torque ntawm cov hmoov hlau nplaum sib nqus muaj kev sib raug zoo zoo nrog rau qhov zoo siab tam sim no ntawm cov hmoov hlau nplaum. Los ntawm linearly kho qhov excitation tam sim no, dynamic tswj ntawm qhov nro nyob rau hauv lub tshav pob tuaj yeem ua tiav, thiab kev ua haujlwm ntawm cov hlau nplaum hlau nres yog qhov ruaj khov heev txawm tias qis heev. Daim ntawv thov kev sib nqus hmoov brakes hauv winding nro tswj cov tshuab, raws li qhia hauv daim duab 4, muaj qhov zoo dua li kev tswj hwm yav dhau los, suav nrog cov qauv yooj yim, qis dua cov nqi ua haujlwm, thiab tswj tau yooj yim dua. Tshwj xeeb, qhov tseeb nro yog kho ncaj qha los ntawm qhov tam sim no, tshem tawm cov txheej txheem ntawm kev ua haujlwm ntawm lwm cov khoom siv hloov kho thiab ua haujlwm yooj yim thiab raug. Ntxiv rau theem dynamic tam sim no them nyiaj ntxiv txhim kho cov khoom zoo.
