Dynamic Braking Nws tseem hu ua Rheostatic braking. Nyob rau hauv hom braking no, DC lub cev muaj zog yog txiav tawm los ntawm cov khoom siv thiab lub braking resistor Rb yog txuas tam sim ntawd hla lub armature. Lub cev muaj zog tam sim no yuav ua haujlwm raws li lub tshuab hluav taws xob thiab tsim cov braking torque.

Dab tsi yog rheostatic braking ntawm DC series lub cev muaj zog?

Dynamic braking, tseem hu ua rheostatic braking, tso cai rau koj ua kom lub cev muaj zog los ntawm kev thim rov qab lub zog ntawm kev taw qhia. Nrog koj tus nres, koj yeej tseem ceeb disconnect koj lub cev muaj zog khiav ntawm nws lub hwj chim qhov chaw. Koj lub cev muaj zog lub rotor yuav pib tig vim tsis ua haujlwm, yog li ua haujlwm raws li lub tshuab hluav taws xob.

Koj txhais li cas los ntawm rheostatic braking?

ib txoj kev ntawm hluav taws xob braking uas lub tshuab hluav taws xob ua haujlwm ua lub tshuab hluav taws xob. Lub zog kinetic ntawm lub cev muaj zog rotor thiab cov khoom txuas txuas yog dissipated hauv qhov pib rheostat lossis tshwj xeeb braking rheostat, thiab lub braking torque yog tsim rau ntawm lub tshuab.

hom rheostatic braking yog dab tsi?

Yeej, muaj peb hom kev siv braking yog siv hauv DC lub cev muaj zog xws li regenerative, dynamic, thiab ntsaws.

Qhov txawv ntawm rheostatic braking thiab ntsaws yog dab tsi?

Plugging muab ntau dua braking torque piv rau rheostatic braking. Txoj kev no feem ntau yog siv los tswj cov elevator, cov cuab yeej siv tshuab,printing presses thiab lwm yam. (iii) Regenerative braking: Regenerative braking yog siv qhov twg, load ntawm lub cev muaj zog inertia siab heev (xws li nyob rau hauv hluav taws xob tsheb ciav hlau).

Ib lub prism yog ib daim duab peb sab, muaj rau lub ntsej muag, qhov twg tag nrho lub ntsej muag (sab saum toj, hauv qab, thiab sab nraud) ntawm lub ntsej muag yog cov duab plaub zoo li txhua tus ob lub ntsej muag opposite sab yog tib yam. Zoo li tag nrho cov duab peb sab, lub duab plaub kuj muaj qhov ntim thiab qhov chaw saum npoo.

Puas yog s altatory conduction tshwm sim nyob rau hauv unmyelinated axons?

S altatory conduction nyob rau hauv unmyelinated axons: pawg ntawm Na + channels ntawm lipid rafts enables micro-s altatory conduction nyob rau hauv C-fibers. Lub peev xwm ua tau (AP), lub cim tseem ceeb ntawm lub paj hlwb, yog nqa los ntawm ob hom axons:
