Taw qhia rau qhov zoo thiab qhov tsis zoo ntawm
ruaj khov hlau nplaum synchronous motors
Lub rotor ceev ntawm cov hlau nplaum ruaj khov synchronous motors yog synchronized nrog ceev ntawm stator magnetic teb. Nws cov txheej txheem ua haujlwm yog tias stator winding txuas nrog rau qhov hloov pauv tam sim no los tsim cov stator rotating magnetic teb, thiab cov hlau nplaum ruaj khov rotor magnetic teb raug ntxias los ntawm stator rotating magnetic teb thiab rotates nrog nws, thiab lub cev muaj zog rotates thiab outputs zog.
Cov txiaj ntsig tseem ceeb ntawm cov hlau nplaum ruaj khov synchronous motors yog lub zog siab ceev, kev ua haujlwm siab, cov qauv yooj yim thiab compact, loj thiab du torque, thiab kev tswj ceev ceev.
1) High zog ceev:Cov khoom siv hlau nplaum neodymium boron sib nqus ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog muaj cov khoom sib nqus zoo heev. Tom qab magnetization, tsis muaj lub zog sab nraud yuav tsum tau ntxiv, thiab muaj zog hlau nplaum tuaj yeem tsim. Nyob rau tib lub sij hawm, lub magnetic teb muaj cov yam ntxwv mus tas li thiab tsis tas yuav tsum tau ntxiv circuits rau excitation (uas yog, energizing tus neeg xyuas pib los tsim ib tug magnetic teb), thiaj li hais tias ib tug me me ntim thiab lub teeb yuag yuav khaws cia. Ntawm rated zog, lub zog ceev ntawm lub cev muaj zog tas mus li nrog tib qho cua sov dissipation thiab ntau dua li ob zaug ntawm induction asynchronous tsav.
2) Kev ua haujlwm siab:Tau txais txiaj ntsig los ntawm cov hlau nplaum ruaj khov nyob rau hauv lub rotor, lub rotor ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog feem ntau tsis tas yuav muaj zog (tshwj tsis yog qee qhov kev pib tus kheej lossis eddy tam sim no poob), uas tuaj yeem txo cov kev poob qis thiab muaj kev ua haujlwm siab.
3) Cov qauv yooj yim thiab compact:Cov hlau nplaum ruaj khov synchronous tsav lub cev muaj zog tsis muaj cov qauv siv hluav taws xob zoo thiab cov qauv kev ua kom muaj zog, uas txo cov kev sib txuam ntawm cov qauv thiab yog cov compact, kom ntseeg tau tias cov hlau nplaum ruaj khov synchronous tsav lub cev muaj zog ua haujlwm ntau dua. Piv nrog rau tiam thib peb, lub stator txoj kab uas hla ntawm lub thib plaub-tiam mus tas li hlau nplaum synchronous lub cev muaj zog nruab rau Toyota Prius tau poob los ntawm 20%, thiab tag nrho cov qauv yog ntau compact thiab me me nyob rau hauv loj.
4) Loj thiab du torque:Tsis pub dhau qhov ntsuas tam sim no, nce qhov tam sim no tuaj yeem nce lub zog ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog. Tsis tas li ntawd, lub rotating magnetic teb tsim los ntawm peb-theem alternating tam sim no nyob rau hauv lub stator kuj tseem ruaj khov, thiab torque pulsation yog me me. Tshwj xeeb tshaj yog nyob rau hauv qis-ceev thiab high-torque tej yam kev mob (xws li pib thiab acceleration theem ntawm lub zog tshiab tsheb), mus tas li hlau nplaum synchronous motors muaj zoo zoo tshaj asynchronous induction motors.
5) Cov kev cai ceev ceev ua tau zoo:Kev sib raug zoo ntawm hluav taws xob, hlau nplaum thiab quab yuam ntawm cov hlau nplaum ruaj khov synchronous motors yog yooj yim dua li ntawm induction asynchronous motors, ua rau lawv yooj yim rau kev tswj thiab tswj. Lub xeev sib npaug ntawm lub asynchronous lub cev muaj zog yog plaub-kev txiav txim, thiab qhov sib npaug ntawm lub rotor thiab stator yog ua ke (qhov tam sim no nyob rau hauv lub rotor yog generated los ntawm kev sib hloov ntawm stator magnetic teb); lub xeev sib npaug ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog yog qhov thib ob-txiav txim siab, thiab cov hlau nplaum ntawm cov hlau nplaum ruaj khov muaj nyob ntawm nws tus kheej. Kev tswj qhov nyuaj yog qhov qis dua li ntawm qhov induction asynchronous lub cev muaj zog nyob rau hauv qis-ceev thiab high-ceev (siab dua li qhov ntsuas ceev) cov xwm txheej.
