Kev thim rov qab ntawm kev siv hluav taws xob ua rau nws siv tau qee yam kev siv hluav taws xob ua lub tshuab hluav taws xob. Qhov no ua rau nws muaj peev xwm tsim ntawm lawv cov hauv paus fais fab nrog ko taw, cua thiab lwm yam tsav.
Cov Lus Qhia

Siv lub tshuab hluav taws xob commutator mus tas li ntawm lub stator ua lub tshuab hluav taws xob yam tsis muaj kev hloov kho. Thaum tsav nws lub thooj av mus rau kev sib hloov nrog ib qho chaw ze rau lub nominal, nws yuav tsim qhov hluav taws xob tas li, tseem nyob ze rau nominal. Qhov polarity ntawm qhov hluav taws xob no yog nyob ntawm cov kev taw qhia nyob rau hauv uas tus ncej tig. Siv cov inductors thiab cov capacitors los lim cov zis hluav taws xob, uas yog, kom tshem tawm tus kheej thiab ua rau lub suab nrov ntawm nws. Electrolytic capacitors tuaj yeem hloov mus rau qhov kev hwm rau polarity, thiab yog tias lawv muaj nyob hauv lim, lub tshuab hluav taws xob tsuas tuaj yeem tig tau hauv ib qho kev coj ua raws li lub polarity.

Kev tsav tsheb rau lub ntiaj teb, uas muaj cov xaim hluav taws xob ntawm lub stator hloov ntawm cov hlau nplaum tas mus li, ua ntej hloov me ntsis: tshem tawm cov kab ntawm cov stator winding kom lawv tsis txuas nrog cov txhuam. Thov siv hluav taws xob tas mus li rau qhov cua ntsawj no - ua ntej los ntawm lub roj teeb, uas tau them los ntawm lub tshuab hluav taws xob zoo ib yam, thiab thaum voltage tshwm ntawm cov txhuam, nws yuav muaj peev xwm los ua kom muaj zog ntawm kev sib tw winding los ntawm lub tshuab hluav taws xob nws tus kheej. Txhawm rau tiv thaiv lub roj teeb kom tsis txhob tawm ntawm lub tshuab hluav taws xob thaum nws tsis tig, siv cov hluav taws xob rov qab tam sim no (lossis cov diode), thiab txhawm rau kom tsis txhob overcharging lub roj teeb, siv cov chaw tswj kev hloov pauv. Ob qho tag nrho kev xa tawm yuav tsum tau tsim rau tib lub zog hluav taws xob zoo li lub tshuab hluav taws xob, thiab lawv cov hloov hluav taws xob tau muab rau hauv cov ntawv pov thawj rau lawv lossis lawv rooj plaub.

Lub tshuab asynchronous hluav taws xob, thaum lub pluaj tsis ua haujlwm, yuav tsis hloov mus rau lub tshuab hluav taws xob, tshwj tsis yog muaj kev ntsuas tshwj xeeb. Txuas peb lub xov tooj hluav taws xob uas tsis txuas rau nws kom lub zog ntawm txhua zaus ntawm oscillatory Circuit Court, ua los ntawm qhov ntsuas cua thiab lub zog ntsuas, yog sib npaug nrog ntau zaus. Txuas lub capacitors raws li hauv qab no: thawj zaug yog nyob rau theem A thiab B, qhov thib ob yog nyob rau theem B thiab C, qhov thib peb yog nyob rau theem A thiab C. Kev tsim hluav taws xob hloov pauv tseem yuav yog peb-theem.

Stepper motors txawv ntawm tag nrho cov tau teev tseg saum toj saud uas lawv xav tau tig ntawm qhov tsawg zaus. Txuas ob lub diodes rau txhua qhov txuas ntawm qhov lub cev muaj zog: ib qho nrog cathode rau cov zis thiab qhov anode rau qhov rho tawm ntawm lub taub lim tau, thiab lwm qhov - qhov taw qhia rau cov zis thiab cathode rau ntxiv ntawm lub peev xwm lim. Cov. Yog li, tag nrho cov lej ntawm diodes yuav yog ob zaug ntawm cov lej ntawm lub cev muaj zog.
