How to measure the basic parameters of the motor?

Lapho sithola injini ezandleni zethu, uma sifuna ukuyilawula, sidinga ukwazi imingcele yayo eyisisekelo.Lezi zinhlaka eziyisisekelo zizosetshenziswa ku-2, 3, 6, kanye no-10 esithombeni esingezansi.Ngokuqondene nokuthi kungani le mingcele isetshenziswa, sizochaza ngokuningiliziwe lapho siqala ukudonsa ifomula.Kufanele ngisho ukuthi ngiwazonda kakhulu amafomula, kodwa angikwazi ukwenza ngaphandle kwamafomula.Esixoxa ngakho kulesi sihloko indlela yokuxhuma inkanyezi yemoto.

Ukumelana nesigaba sama-Rs

Isilinganiso sale pharamitha silula.Sebenzisa i-multimeter esandleni sakho ukukala ukumelana phakathi kwanoma yiziphi izigaba ezimbili, bese uhlukanisa ngo-2 ukuze uthole ukumelana nesigaba sama-Rs enjini.

Inani lamapheya wezigxobo n

Lesi silinganiso sidinga ukunikezwa kwamandla okulawulwayo okunomkhawulo wamanje.Faka amandla kunoma yiziphi izigaba ezimbili zezintambo zezigaba ezintathu zenjini esandleni sakho.Eyamanje okudingeka ikhawulelwe ingu-1A, futhi amandla ogesi okudingeka adlule kuwo ngu-V=1*Rs (amapharamitha akalwe ngenhla).Bese uvula i-rotor ngesandla, uzozizwa ukumelana.Uma ukumelana kungabonakali, ungaqhubeka nokwandisa i-voltage kuze kube yilapho kukhona ukumelana okucacile kokujikeleza.Lapho i-motor izungeza indilinga eyodwa, inani lezikhundla ezizinzile ze-rotor inombolo yamapheya wezigxobo zenjini.

Ls stator inductance

Lokhu kudinga ukusetshenziswa kwebhuloho ukuhlola i-inductance phakathi kwanoma yiziphi izigaba ezimbili ze-stator, futhi inani elitholiwe lihlukaniswa ngo-2 ukuze uthole i-Ls.

Emuva EMF Ke

Kuhlelo lokulawula lwe-FOC, le mingcele embalwa ehlobene nemoto yanele.Uma ukulingiswa kwe-matlab kuyadingeka, amandla e-electromotive angemuva enjini nawo ayadingeka.Lesi silinganiso sepharamitha sinzima kakhulu.Kudingeka ukuzinzisa i-motor kuma-n revolutions, bese usebenzisa i-oscilloscope ukukala i-voltage yezigaba ezintathu ngemuva kokuthi ama-motor revolutions azinzile, njengoba kuboniswe esithombeni esingezansi:

Kufomula engenhla, i-Vpp iyinani le-volt phakathi kwenani eliphakeme kanye nomkhombe we-waveform.

Lapho u-Te=60/(n*p), n eyiyunithi yesivinini sikamishini engu-rpm, futhi u-p uyinombolo yamapheya wezigxobo.Uma injini igcina ama-revolution angu-1000, n ilingana no-1000.

Manje kune-algorithm ebizwa ngokuthi i-motor parameter identification.Lokhu kuwukusebenzisa i-algorithm ukuze isilawuli semoto sikwazi ukuba nomsebenzi wokuhlola we-multimeter noma ibhuloho, bese kuba yindaba yokulinganisa nokubala.Ukuhlonza ipharamitha kuzochazwa ngokuningiliziwe ngokubhekiselwa kumafomula afanelekile kamuva.
