How to measure the basic parameters of the motor?

Xa sifumana injini ezandleni zethu, ukuba sifuna ukuyilawula, kufuneka sazi iiparamitha zayo ezisisiseko.Ezi parameters zisisiseko ziya kusetyenziswa ku-2, 3, 6, no-10 kumzobo ongezantsi.Ngokuphathelele kutheni ezi parameters zisetyenziswa, siya kuchaza ngokweenkcukacha xa siqala ukutsala ifomula.Kuya kufuneka nditsho ukuba ndiyithiyile iifomula kakhulu, kodwa andinakwenza ngaphandle kweefomula.Into esiyixubushayo kweli nqaku yindlela yokudibanisa inkwenkwezi yemoto.

Rs isigaba ukumelana

Umlinganiselo wale parameter ulula. Sebenzisa i-multimeter esandleni sakho ukulinganisa ukuchasana phakathi kwazo naziphi na izigaba ezibini, kwaye emva koko uyahlule nge-2 ukufumana ukuxhathisa kwesigaba ii-Rs zemoto.

Inani lezibini zepali n

Lo mlinganiselo ufuna unikezelo lwamandla olulawulwayo olunomlinganiselo wangoku.Faka amandla kuzo naziphi na izigaba ezibini zocingo lwesigaba esithathu senjini esandleni sakho.Ikhoyo ngoku ekufuneka ikhawulelwe yi-1A, kwaye i-voltage ekufuneka idluliselwe kuyo yi-V = 1 * Rs (iiparamitha ezilinganiswe ngasentla).Emva koko ujike i-rotor ngesandla, uya kuziva ukuchasana.Ukuba ukuchasana akubonakali, unokuqhubeka nokunyusa i-voltage de kubekho ukuchasana kokujikeleza okucacileyo.Xa i-motor ijikeleza isangqa esinye, inani lezikhundla ezizinzile ze-rotor linani leepali zeepali ze-motor.

Ls stator inductance

Oku kufuna ukusetyenziswa kwebhuloho ukuvavanya i-inductance phakathi kwazo naziphi na izigaba ezimbini ze-stator, kwaye ixabiso elifunyenweyo lihlukaniswe ngu-2 ukufumana i-Ls.

Emva EMF Ke

Kwinkqubo yolawulo ye-FOC, ezi parameters zimbalwa ezinxulumene nemoto zanele. Ukuba i-matlab simulation iyafuneka, i-electromotive force yangasemva yemoto nayo iyafuneka.Lo mlinganiselo weparameter unzima kancinci.Kuyimfuneko ukuzinzisa i-motor kwi-n revolutions, kwaye emva koko usebenzise i-oscilloscope ukulinganisa i-voltage yezigaba ezithathu emva kokuba ii-motor revolutions zizinzile, njengoko kubonisiwe kulo mfanekiso ungezantsi:

Kule fomyula ingentla, i-Vpp lixabiso le-volt phakathi kwencopho kunye nomkhombe we-waveform.

Apho iTe=60/(n*p), n yiyunithi yesantya somatshini rpm, kwaye p linani leeperi zepali.Ukuba i-motor igcina i-1000 revolutions, n ilingana ne-1000.

Ngoku kukho i-algorithm ebizwa ngokuba yi-motor parameter identification. Oku kukusebenzisa i-algorithm ukwenzela ukuba umlawuli wemoto abe nomsebenzi wokuvavanya we-multimeter okanye ibhuloho, kwaye ke yinto yokulinganisa kunye nokubala. Ukuchongwa kweparamitha kuya kuchazwa ngokweenkcukacha ngokubhekiselele kwiifomula ezifanelekileyo kamva.
