Qhov tseem ceeb sib txawv ntawm lub cev muaj zog los ntawm zaus hloov dua siab tshiab rau cov neeg muaj zog los ntawm lub zog tseem ceeb, nws ua haujlwm nyob rau hauv ib sab ntawm lub zog loj, thiab ntawm qhov tod tes, lub zog WaveForm yog non-abusoidal. Los ntawm plaub lub series tsom xam ntawm Voltage Waveform, lub zog hluav taws xob WaveForm muaj ntau dua 2n kev sib zog ua ke (tswj cov nthwv cua) (tus naj npawb ntawm cov nthwv dej uas muaj nyob hauv txhua ib nrab ntawm kev tswj hwm yog n). Thaum Spev SC cov hloov kho cov hwj chim thiab siv rau lub cev muaj zog, cov nthwv dej tam sim no yuav tshwm sim los ua cov sine yoj nrog superimposics. Cov harmonic tam sim no yuav tsim lub pulsating sib nqus flux tivthaiv nyob rau hauv lub sib nqus fluxtuent, thiab hais tias lub ntsiab sib nqus flux muaj cov pulsating sib nqus flux tivthaiv. Lub pulsating sib nqus flux tivthaiv kuj ua rau lub sib nqus Circuittic zoo li yuav noo, uas muaj cov kev cuam tshuam hauv qab no ntawm lub zog:
1.pwsating sib nqus gragnetic flux yog tsim
Kev poob thiab ua haujlwm ua tau zoo. Vim tias cov zis ntawm cov muaj zog sib txawv hluav taws xob cov khoom siv muaj zog, cov kev sib raug zoo no yuav tsim cov tooj liab ua kom zoo nkauj thiab siv hlau ua haujlwm. Txawm tias Spij Sinusoidal Technology, uas tau siv dav tam sim no, tsuas yog txuas lub cev muaj zog ntawm cov kev ua haujlwm ruaj khov ntawm cov tsav tsheb ntawm qis ceev. Thiab cov kev sib raug zoo dua tsis tsuas yog tsis txo qis, tab sis nce. Feem ntau, piv nrog lub zog zaus Sine fais fab mov, kev ua tau zoo yog txo los ntawm kev ua kom hloov dua siab tshiab fais fab fais fab fais fab muab yog qhov teeb meem loj.
b) Ua kom muaj hluav taws xob kev co hluav taws xob thiab suab nrov. Vim muaj kev muaj ntawm cov kev txiav txim siab ua kom muaj kev sib raug zoo, hluav taws xob kev co thiab suab nrov yuav tseem tsim tawm. Yuav ua li cas txo qis kev co thiab suab nrov yog qhov teeb meem rau sine yoj powered motors. Rau lub cev muaj zog powered los ntawm inverter, qhov teeb meem yuav nyuaj dua vim yog cov tsis-sinusoidal xwm ntawm lub zog.
c) Tsawg zaus pulsating torque tshwm sim ntawm qhov nrawm nrawm. Harthonic magnetomotive quab yuam thiab kev sib cav sib tua hluav taws xob torque, yog li cuam tshuam rau lub cev muaj zog ua haujlwm. Txawm hais tias SPWB MODULATION hom yog siv, piv nrog lub zog zaus Sine zog, uas yuav tsim cov kev ua haujlwm qis thiab cuam tshuam rau kev ua haujlwm ruaj khov ntawm lub cev muaj zog ntawm kev nrawm nrawm.
2.generate impulse voltage thiab lawb voltage (tam sim no) rau rwb thaiv tsev
a) surge voltage tshwm sim. Thaum lub cev muaj zog tab tom khiav, cov siv voltage yog feem ntau superimposes nrog cov kev hloov pauv hluav taws xob tau nce qib siab, ua rau kev poob siab dua rau lub rwb thaiv tsev.
b) Ua kom muaj lub siab voltage thiab axial tam sim no. Lub cim ntawm co ncej voltage feem ntau yog vim muaj cov peev txheej sib nqus thiab cov hluav taws xob tsis sib xws, tab sis nws yog qhov tseem ceeb hauv cov motors muaj zog los ntawm cov khoom siv hluav taws xob ntau zaus. Yog hais tias tus ncej voltage yog siab dhau, lubrical lub xeev ntawm cov roj zaj duab xis nruab nrab ntawm tus ncej thiab cov kabmob yuav puas, thiab lub neej pabcuam yuav ua kom luv.
c) sov li cas dissipation cuam tshuam cov nyhuv cua sov dissipation nyhuv thaum khiav ntawm qis ceev. Vim yog cov kev tswj kev loj loj ntawm ntau yam ntawm cov muaj zog zaus lub cev muaj zog, nws feem ntau sau ntawm kev nrawm ntawm tsawg zaus. Nyob rau lub sijhawm no, vim tias qhov nrawm yog tsawg heev, cua txias muab los ntawm tus kheej kiv cua txias siv los ntawm cov nyhuv cua txias yog txo, thiab kev ua haujlwm ywj pheej yuav tsum tau siv.
Neeg kho tshuab cawv yog qhov tsis tshua muaj kev resonance, feem ntau, txhua yam cuab yeej siv tshuab yuav ua cov khoom tshwm sim ntawm kev ua haujlwm. Txawm li cas los xij, lub cev muaj zog khiav ntawm cov hluav taws xob tas li thiab nrawm yuav tsum zam kev resonance nrog cov tshuab hluav taws xob teb tau teb txog 50z. Thaum lub cev muaj zog tau ua haujlwm nrog cov kev hloov pauv ntau zaus, cov kev ua haujlwm ntau muaj ntau yam, uas yog qhov yooj yim los ua kom nws resonate ntawm ib qho zaus.
