Kev piav qhia ntawm DC Motors

Txhawm rau kom ua tiav kev sib hloov hluav taws xob, lub teeb liab txoj haujlwm yog tsim nyog los tswj lub voj voog. Nyob rau hauv thaum ntxov hnub, txoj hauj lwm teeb liab tau txais siv electromechanical txoj hauj lwm sensors. Tam sim no, hluav taws xob txoj hauj lwm sensors los yog lwm txoj kev tau maj mam siv kom tau txais txoj hauj lwm teeb liab. Txoj kev yooj yim tshaj plaws yog siv lub peev xwm teeb liab ntawm armature winding raws li txoj hauj lwm teeb liab.
Yuav kom ua tiav kev tswj ntawm lub cev muaj zog, lub teeb liab ceev yog tsim nyog. Txoj kev yooj yim tshaj plaws ntawm kev tau txais cov teeb liab ceev los ntawm kev tau txais cov cim qhia zoo sib xws yog kev sib xyaw ua ke ntawm zaus ntsuas tachometer generator thiab hluav taws xob circuits.
Lub commutation Circuit Court ntawm DC brushless lub cev muaj zog muaj ob ntu: tsav thiab tswj, uas tsis yooj yim sib cais, tshwj xeeb tshaj yog nyob rau hauv qis-power circuits qhov twg ob feem ntau koom ua ke rau hauv ib qho kev sib koom ua ke.
Nyob rau hauv high-power motors, tsav Circuit Court thiab tswj Circuit Court tuaj yeem ua ke sib cais. Kev tsav tsheb Circuit Court outputs hluav taws xob fais fab, tsav lub armature winding ntawm lub cev muaj zog, thiab yog tswj los ntawm kev tswj Circuit Court. Lub voj voog tsav tsheb tau hloov los ntawm lub xeev kev nthuav dav mus rau lub plawv dhia dav hloov pauv hloov lub xeev, thiab cov khoom siv hluav taws xob sib txuas kuj tau hloov los ntawm ib qho kev sib cais transistor mus rau ib qho kev sib xyaw ua ke. Modular integrated circuits yog tsim los ntawm lub hwj chim bipolar transistors, lub zog teb-zoo transistors, thiab cais lub rooj vag-tshuaj cuam tshuam bipolar transistors. Txawm hais tias kev sib cais lub rooj vag-tshuaj cuam tshuam bipolar transistors kim dua, los ntawm qhov kev xav ntawm kev ntseeg siab, kev nyab xeeb, thiab kev ua tau zoo, xaiv lawv tseem tsim nyog dua.
Kev tswj Circuit Court yog siv los tswj qhov ceev, kev taw qhia, tam sim no (los yog torque) ntawm lub cev muaj zog, nrog rau kev tiv thaiv lub cev muaj zog ntawm overcurrent, overvoltage, overheating, thiab lwm yam. Cov saum toj no tsis tau yooj yim hloov dua siab tshiab rau hauv analog signals, uas yog kuj. yooj yim tswj. Txawm li cas los xij, los ntawm kev txhim kho kev xav, qhov tsis sib xws ntawm lub cev muaj zog yuav tsum tau hloov mus rau hauv cov lej digital thiab tswj los ntawm kev tswj hwm digital circuits. Tam sim no, tswj circuits yog tsim los ntawm peb hom: tshwj xeeb integrated circuits, microprocessors, thiab digital signal processors. Nyob rau hauv cov xwm txheej uas cov kev cai tswj lub cev muaj zog tsis siab, kev siv cov kev sib koom ua ke sib koom ua ke los tsim cov kev tswj xyuas Circuit Court yog ib qho yooj yim thiab siv tau. Kev siv cov teeb liab digital processors los tsim cov kev tswj xyuas Circuit Court yog txoj kev txhim kho yav tom ntej, thiab cov teeb liab cuam tshuam nrog cov teeb liab processors yuav raug qhia hauv ntu nram qab no ntawm AC synchronous servo motors.
DC brushless motors yog ib hom tshiab ntawm lub cev muaj zog sai sai hauv kev ua haujlwm ntawm lub zog me me. Vim qhov kev xav tau tshwj xeeb DC brushless motors hauv ntau daim ntawv thov, muaj ntau hom DC brushless motors. Feem ntau, muaj cov qauv ntawm lub cev tsis muaj zog rau lub computer sab nraud nco thiab VCD, DVD, CD spindle tsav, sab nraud rotor lub cev muaj zog cov qauv rau cov tshuab ua pa me me, cov qauv sib nqus sib nqus thiab cov qauv tsim rau cov khoom siv hauv tsev, multipolar thiab sab nraud rotor qauv rau cov tsheb kauj vab hluav taws xob. . Txhawm rau ua kom tau raws li qhov xav tau ntawm kev lag luam loj thiab tus nqi qis, kev tsim cov DC brushless motors yuav tsum tsim kev lag luam ntawm cov nplai. Yog li ntawd, DC brushless motors yog ib qho kev lag luam nrog kev nqis peev siab thiab kev tsim tawm siab. Nyob rau tib lub sijhawm, peb yuav tsum coj mus rau hauv tus account qhov kev loj hlob tsis tu ncua ntawm kev ua lag luam, xws li kev hloov pauv ntawm 3A mus rau 3D rau cov tshuab cua txias hauv tsev, uas yuav tsum muaj ntau lub zog me me thiab nruab nrab DC brushless DC motors. Kev tshawb fawb thiab kev loj hlob ntawm me me thiab nruab nrab lub zog DC brushless motors kuj tau dhau los ua haujlwm ceev.
