How to measure the basic parameters of the motor?

Ha re fumana enjene matsohong a rona, haeba re batla ho e thapisa, re hloka ho tseba lintlha tsa eona tsa mantlha.Lintlha tsena tsa mantlha li tla sebelisoa ho 2, 3, 6, le 10 setšoantšong se ka tlase.Mabapi le hore na ke hobane'ng ha li-parameter tsena li sebelisoa, re tla hlalosa ka ho qaqileng ha re qala ho hula foromo.Ke tlameha ho bolela hore ke hloile liforomo haholo, empa ha ke khone ho etsa ntle le liforomo.Seo re se tšohlang sehloohong sena ke mokhoa oa ho hokahanya ha linaleli tsa motlakase.

Rs mohato oa ho hanyetsa

Tekanyo ea parameter ena e batla e le bonolo.Sebelisa multimeter letsohong la hau ho lekanya khanyetso lipakeng tsa mekhahlelo efe kapa efe e 'meli, ebe u e arola ka 2 ho fumana mohanyetsi oa karolo ea Rs ea enjene.

Palo ea lipara tsa lipalo n

Tekanyo ena e hloka phepelo ea motlakase e laoloang e nang le moeli oa hajoale.Sebelisa matla ho mekhahlelo efe kapa efe e 'meli ea methati e meraro ea enjene letsohong la hau.Hona joale e lokelang ho lekanyetsoa ke 1A, 'me motlakase o lokelang ho fetisoa ke V = 1 * Rs (mekhahlelo e lekantsoeng ka holimo).Ebe u fetola rotor ka letsoho, u tla ikutloa u hanyetsa.Haeba khanyetso e sa totobala, u ka tsoela pele ho eketsa motlakase ho fihlela ho na le khanyetso e hlakileng ea ho potoloha.Ha motlakase o potoloha selikalikoe se le seng, palo ea maemo a tsitsitseng a rotor ke palo ea lipara tsa palo ea motlakase.

Ls stator inductance

Sena se hloka tšebeliso ea borokho ho hlahloba inductance pakeng tsa mekhahlelo leha e le efe e 'meli ea stator,' me boleng bo fumanoang bo arotsoe ke 2 ho fumana Ls.

Khutlela EMF Ke

Bakeng sa lenaneo la taolo ea FOC, li-parameter tsena tse 'maloa tse amanang le motlakase li lekane.Haeba matlab ketsiso e hlokahala, ho boetse ho hlokahala matla a morao a motlakase a motlakase.Tekanyo ena ea parameter e thata haholoanyane.Hoa hlokahala ho tsitsisa motlakase ho n revolutions, ebe o sebelisa oscilloscope ho lekanya motlakase oa mekhahlelo e meraro ka mor'a hore liphetoho tsa motlakase li tsitsitse, joalokaha ho bontšitsoe setšoantšong se ka tlase:

Ka foromo e kaholimo, Vpp ke boleng ba volt lipakeng tsa tlhoro le sekoti sa waveform.

Moo Te=60/(n*p), n ke mechanical speed unit rpm, le p ke palo ea lipara tsa lipalo.Haeba motlakase o boloka liphetoho tse 1000, n e lekana le 1000.

Hona joale ho na le algorithm e bitsoang motor parameter identification.Sena ke ho sebelisa algorithm ho etsa hore molaoli oa motlakase a be le ts'ebetso ea tlhahlobo ea multimeter kapa borokho, ebe ke taba ea ho lekanya le ho bala.Khethollo ea paramethara e tla hlalosoa ka botlalo ho ipapisitsoe le liforomo tse amehang hamorao.
