Muaj ob hom tsav tsheb uas nquag siv hauv tsheb tshiab: cov hlau nplaum ruaj khov synchronous motors thiab AC asynchronous motors. Feem ntau lub zog tshiab tsheb siv cov hlau nplaum ruaj khov synchronous motors, thiab tsuas yog qee lub tsheb siv AC asynchronous motors.
Tam sim no, muaj ob hom tsav tsheb uas nquag siv hauv tsheb tshiab: cov hlau nplaum ruaj khov synchronous motors thiab AC asynchronous motors. Feem ntau lub zog tshiab tsheb siv cov hlau nplaum ruaj khov synchronous motors, thiab tsuas yog qee lub tsheb siv AC asynchronous motors.
Ua hauj lwm hauv paus ntsiab lus ntawm mus tas li hlau nplaum synchronous lub cev muaj zog:
Energizing lub stator thiab rotor generates ib rotating magnetic teb, ua rau cov txheeb ze txav ntawm ob. Txhawm rau kom lub rotor txiav cov kab sib nqus thiab tsim kom muaj tam sim no, qhov kev sib hloov ceev yuav tsum tau qeeb dua qhov kev sib hloov ceev ntawm stator lub rotating magnetic teb. Txij li thaum ob qho tib si ib txwm khiav asynchronously, lawv hu ua asynchronous motors.
Ua hauj lwm hauv paus ntsiab lus ntawm AC asynchronous lub cev muaj zog:
Energizing lub stator thiab rotor generates ib rotating magnetic teb, ua rau cov txheeb ze txav ntawm ob. Txhawm rau kom lub rotor txiav cov kab sib nqus thiab tsim kom muaj tam sim no, qhov kev sib hloov ceev yuav tsum tau qeeb dua qhov kev sib hloov ceev ntawm stator lub rotating magnetic teb. Txij li thaum ob qho tib si ib txwm khiav asynchronously, lawv hu ua asynchronous motors. Txij li thaum tsis muaj kev sib txuas ntawm lub stator thiab lub rotor, nws tsis yog tsuas yog yooj yim hauv cov qauv thiab sib dua hauv qhov hnyav, tab sis kuj muaj kev ntseeg siab dua hauv kev ua haujlwm thiab muaj zog dua DC motors.
Cov hlau nplaum tas mus li synchronous motors thiab AC asynchronous motors txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo hauv cov ntawv thov sib txawv. Cov hauv qab no yog qee qhov kev sib piv:
1. Efficiency: Qhov ua tau zoo ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog feem ntau siab dua li ntawm AC asynchronous lub cev muaj zog vim nws tsis tas yuav muaj qhov sib nqus tam sim no los tsim cov hlau nplaum. Qhov no txhais tau hais tias nyob rau hauv tib lub zog tso zis, cov hlau nplaum ruaj khov synchronous lub cev muaj zog siv tsawg zog thiab tuaj yeem muab sijhawm ntev dua.
2. Fais fab ntom ntom: lub zog ntom ntom ntawm lub cev muaj zog tas mus li yog ntau dua li cov rotynchronous vim tias nws lub rotor tsis tas yuav windings thiab tuaj yeem yog li muaj ntau dua. Qhov no ua rau cov hlau nplaum ruaj khov synchronous motors muaj txiaj ntsig zoo hauv qhov chaw txwv tsis pub siv xws li tsheb hluav taws xob thiab drones.
3. Tus nqi: Tus nqi ntawm AC asynchronous motors feem ntau qis dua li cov hlau nplaum ruaj khov synchronous motors vim nws cov qauv rotor yog qhov yooj yim thiab tsis tas yuav cov hlau nplaum ruaj khov. Qhov no ua rau AC asynchronous motors muaj txiaj ntsig zoo hauv qee qhov kev siv nyiaj txiag, xws li cov khoom siv hauv tsev thiab cov khoom siv.
4. Kev tswj tsis yooj yim: Kev tswj tsis yooj yim ntawm cov hlau nplaum ruaj khov synchronous motors feem ntau yog siab dua li ntawm AC asynchronous motors vim tias nws yuav tsum muaj kev tswj xyuas qhov sib nqus kom ua tau zoo thiab muaj zog ceev. Qhov no yuav tsum muaj kev tswj xyuas ntau dua thiab cov khoom siv hluav taws xob, yog li hauv qee qhov kev siv yooj yim AC asynchronous motors yuav tsim nyog dua.
Hauv cov ntsiab lus, cov hlau nplaum ruaj khov synchronous motors thiab AC asynchronous motors txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab lawv yuav tsum raug xaiv raws li cov kev thov tshwj xeeb thiab cov kev xav tau. Nyob rau hauv high-efficiency thiab high-power-density daim ntaub ntawv xws li hluav taws xob tsheb, mus tas li hlau nplaum synchronous motors yog feem ntau zoo dua; thaum nyob rau hauv ib co nqi-sensitive daim ntaub ntawv, AC asynchronous motors tej zaum yuav haum dua.
Feem ntau ua txhaum ntawm lub zog tshiab lub tsheb tsav tsheb muaj xws li hauv qab no:
- Rwb thaiv tsev txhaum: Koj tuaj yeem siv lub ntsuas hluav taws xob los hloov kho rau 500 volts thiab ntsuas peb theem ntawm lub cev muaj zog uvw. Tus nqi rwb thaiv tsev ib txwm yog nyob nruab nrab ntawm 550 megohms thiab infinity.
- Hnav splines: Lub cev muaj zog hums, tab sis lub tsheb tsis teb. Disassemble lub cev muaj zog los xyuas qhov degree ntawm hnav ntawm cov hniav spline thiab tus Tsov tus tw.
- Lub cev muaj zog kub: muab faib ua ob qhov xwm txheej. Thawj yog qhov kub siab tiag tiag tshwm sim los ntawm lub twj tso kua mis dej tsis ua haujlwm lossis tsis muaj cov dej txias. Qhov thib ob yog tshwm sim los ntawm lub cev muaj zog qhov kub thiab txias sensor raug puas, yog li nws yuav tsum tau siv qhov kev tiv thaiv ntau yam ntawm multimeter los ntsuas ob qhov ntsuas kub.
- Kev daws teeb meem tsis ua haujlwm: muab faib ua ob qhov xwm txheej. Thawj yog qhov kev tswj xyuas hluav taws xob puas lawm thiab qhov kev ua txhaum no raug tshaj tawm. Qhov thib ob yog vim qhov kev puas tsuaj tiag tiag ntawm tus neeg daws teeb meem. Lub sine, cosine thiab excitation ntawm lub cev muaj zog daws kuj raug ntsuas cais los ntawm kev siv cov teeb tsa resistor. Feem ntau, qhov tseem ceeb ntawm sine thiab cosine yog ze rau 48 ohms, uas yog sine thiab cosine. Lub excitation kuj txawv los ntawm kaum ob ohms, thiab excitation yog ≈ 1/2 sine. Yog tias qhov kev daws teeb meem ua tsis tiav, qhov kev tawm tsam yuav txawv heev.
Lub splines ntawm lub zog tshiab lub tsheb tsav lub cev muaj zog yog hnav thiab tuaj yeem kho los ntawm cov kauj ruam hauv qab no:
1. Nyeem lub kaum sab xis ntawm lub cev muaj zog ua ntej kho.
2. Siv cov khoom siv rau xoom-kho tus daws teeb meem ua ntej sib dhos.
3. Tom qab kev kho tiav, sib dhos lub cev muaj zog thiab qhov sib txawv thiab tom qab ntawd xa lub tsheb. #electricdrivecyclization # #electricmotorconcept # #motorsinnovationtechnology # # motorprofessionalknowledge # # motorovercurrent # # #深蓝superelectricdrive #
