Tam sim no cov xwm txheej ntawm brushless DC lub cev muaj zog daim ntawv thov

Brushless DC lub cev muaj zog(BLDCM) yog tsim los ntawm lub hauv paus ntawm brushless DC lub cev muaj zog, tab sis nws cov tsav tam sim no yog raws nraim AC; Brushless DC lub cev muaj zog yuav muab faib ua brushless tus nqi lub cev muaj zog thiab brushless lub caij lub cev muaj zog. Feem ntau, brushless lub cev muaj zog tsav tam sim no muaj ob hom, ib tug yog trapezoidal nthwv dej (feem ntau "square yoj"), lwm qhov yog sine yoj.Qee lub sijhawm qub yog hu ua brushless DC lub cev muaj zog, tom kawg yog hu ua AC servo lub cev muaj zog, tshwj xeeb, nws kuj yog ib hom AC servo lub cev muaj zog.

Yuav kom txo tau lub sijhawm ntawm inertia, brushless DC motors feem ntau txais yuav ib qho "elongated" qauv.Brushless DC motors yog ntau me me nyob rau hauv qhov hnyav thiab ntim tshaj brushless DC motors, thiab lub sij hawm sib txuas ntawm inertia tuaj yeem txo los ntawm 40% -50 %.Vim cov teeb meem ua haujlwm ntawm cov khoom siv hlau nplaum ruaj khov, lub peev xwm dav dav ntawm brushless DC lub cev muaj zog qis dua 100KW.
Hom lub cev muaj zog zoo linearity ntawm txhua yam yam ntxwv thiab tswj cov yam ntxwv, dav ceev ntau yam, lub neej ntev, yooj yim txij nkawm thiab suab nrov, thiab tsis muaj cov teeb meem tshwm sim los ntawm txhuam, yog li no lub cev muaj zog muaj peev xwm siv tau zoo hauv tswj qhov system.
DC lub cev muaj zog yog qhov ntxov tshaj plaws lub cev muaj zog, txog thaum kawg ntawm lub xyoo pua puv 19, uas tuaj yeem muab faib ua commutator thiab commutator yam tsis muaj ob pawg.Dc lub cev muaj zog muaj cov yam ntxwv zoo ntawm dc lub cev muaj zog ntawm cov qauv, nqe, txij nkawm tshaj ac lub cev muaj zog, Tab sis vim hais tias ntawm ac lub cev muaj zog tswj teeb meem tsis tau zoo heev, thiab dc lub cev muaj zog ceev tswj kev ua tau zoo, pib yooj yim, muaj peev xwm thauj khoom pib, thiab lwm yam, yog li tam sim no ntawm dc lub cev muaj zog tseem siv dav, tshwj xeeb tshaj yog nyob rau hauv SCR tuaj. dc zog.
Daim ntawv thov xwm txheej:Daim ntawv thov ntawm cov khoom siv hluav taws xob yog suav tsis txheeb.Kiv cua, rab chais, thiab lwm yam. Tsis siv neeg lub qhov rooj, tsis siv neeg xauv thiab cov ntaub thaiv tsis siv neeg hauv tsev so yog txhua yam siv nrog DC motors.DC motors yog dav siv nyob rau hauv dav hlau, tso tsheb hlau luam, radar thiab lwm yam riam phom thiab khoom siv.DC lub cev muaj zog kuj tau lug siv nyob rau hauv locomotive traction, xws li railway locomotive DC traction motor, subway locomotive DC traction motor, locomotive DC auxiliary lub cev muaj zog, mining locomotive DC traction lub cev muaj zog, Marine DC lub cev muaj zog thiab lwm yam.
