How to measure the basic parameters of the motor?

Lokacin da muka sami mota a hannunmu, idan muna so mu horar da shi, muna buƙatar sanin ainihin sigoginsa.Za a yi amfani da waɗannan sigogi na asali a cikin 2, 3, 6, da 10 a cikin hoton da ke ƙasa.Game da dalilin da yasa ake amfani da waɗannan sigogi, za mu yi bayani dalla-dalla lokacin da muka fara ja da dabara.Dole ne in ce na fi ƙin ƙima, amma ba zan iya yin ba tare da dabara ba.Abin da muke tattaunawa a cikin wannan labarin shine hanyar haɗin tauraron motar.

Rs juriya lokaci

Ma'aunin wannan siga yana da sauƙi.Yi amfani da multimeter a hannunka don auna juriya tsakanin kowane matakai biyu, sannan ka raba shi da 2 don samun juriya na lokaci Rs na motar.

Adadin sanduna biyu n

Wannan ma'aunin yana buƙatar kayyade samar da wutar lantarki tare da iyakancewa na yanzu.Aiwatar da wuta zuwa kowane nau'i biyu na wayoyi uku na motar da ke hannunka.A halin yanzu da ake buƙatar iyakance shine 1A, kuma ƙarfin lantarki da ake buƙatar wuce shi shine V = 1 * Rs ( sigogin da aka auna a sama).Sa'an nan kuma juya rotor da hannu, za ku ji juriya.Idan juriya ba ta bayyana ba, za ku iya ci gaba da ƙara ƙarfin wutar lantarki har sai an sami juriyar jujjuyawa.Lokacin da motar ta juya da'irar ɗaya, adadin tabbatattun matsayi na rotor shine adadin nau'i-nau'i na motar.

Ls stator inductance

Wannan yana buƙatar amfani da gada don gwada inductance tsakanin kowane nau'i biyu na stator, kuma ƙimar da aka samu ta raba ta 2 don samun Ls.

Baya EMF Ke

Don shirin sarrafa FOC, waɗannan ƴan sigogin da ke da alaƙa da motar sun isa.Idan ana buƙatar simintin matlab, ana buƙatar ƙarfin lantarki na baya na motar.Wannan ma'aunin ma'aunin yana da ɗan damuwa.Wajibi ne don daidaita motar a cikin juyin juya halin n, sannan a yi amfani da oscilloscope don auna ƙarfin lantarki na matakai uku bayan juyin juya halin motar ya tsayayye, kamar yadda aka nuna a cikin hoton da ke ƙasa:

A cikin dabarar da ke sama, Vpp ita ce ƙimar volt tsakanin kololuwa da tudun motsin igiyar ruwa.

Inda Te=60/(n*p), n shine naúrar gudun injina rpm, p kuma shine adadin nau'in sanda.Idan motar tana kiyaye juyi 1000, n daidai yake da 1000.

Yanzu akwai wani algorithm da ake kira motor parameter identification.Wannan shine don amfani da algorithm don ba da damar mai sarrafa motar samun aikin gwaji na multimeter ko gada, sa'an nan kuma lamari ne na aunawa da lissafi.Za a yi bayanin gano siga dalla-dalla tare da la'akari da dabarar da suka dace daga baya.
