How to measure the basic parameters of the motor?

Kana isu tikawana mota mumaoko edu, kana tichida kuidzora, isu tinofanirwa kuziva maparamita ayo ekutanga.Aya maparamita akakosha achashandiswa mu2, 3, 6, uye gumi mumufananidzo uri pazasi.Nekuda kwekuti sei maparamita aya achishandiswa, isu tichatsanangura zvakadzama patinotanga kudhonza formula.Ndinofanira kutaura kuti ndinovenga mafomula zvakanyanya, asi ini handikwanise kuita pasina maformula.Zvatiri kukurukura munyaya ino inzira yekubatanidza nyeredzi yemota.

Rs phase resistance

Kuyera kweiyi parameter kuri nyore. Shandisa multimeter muruoko rwako kuyera kupokana pakati pezvikamu zviviri, uye woipatsanura ne2 kuti uwane kupikisa kwechikamu Rs yemota.

Nhamba yemapuranga maviri n

Kuyera uku kunoda magetsi akadzorwa ane miganhu iripo.Isa simba kune chero zvikamu zviviri zvetatu-chikamu wiring yemota iri muruoko rwako.Ikozvino iyo inoda kuganhurirwa ndeye 1A, uye iyo voltage inoda kupfuudzwa ndeye V = 1 * Rs (maparamita akayerwa pamusoro).Zvadaro shandura rotor neruoko, iwe uchanzwa kuramba.Kana kushorwa kusiri pachena, iwe unogona kuramba uchiwedzera voltage kusvika paine pachena kutenderera kupikisa.Kana mota ichitenderera imwe denderedzwa, nhamba yenzvimbo dzakagadzikana dze rotor ndiyo nhamba yemapole pairs emota.

Ls stator inductance

Izvi zvinoda kushandiswa kwebhiriji kuedza inductance pakati pezvikamu zviviri zve stator, uye kukosha kwakawanikwa kunoparadzaniswa ne2 kuti uwane Ls.

Kumashure EMF Ke

Kune iyo FOC yekudzora chirongwa, aya mashoma ma paramita ane hukama nemota anokwana. Kana matlab simulation ichidikanwa, iyo yekumashure electromotive simba remota inodiwa zvakare.Iyi chiyero chiyero chinonetsa zvishoma.Izvo zvinodiwa kudzikamisa mota pa n revolutions, uye wozoshandisa oscilloscope kuyera voltage yezvikamu zvitatu mushure mekuchinja kwemotor kugadzikana, sezvakaratidzwa mumufananidzo uri pasi apa:

Mune iyo fomula iri pamusoro, Vpp ndiyo kukosha kwevolt pakati pepamusoro uye mugero weiyo waveform.

Ipo Te=60/(n*p), n ndiyo mechanical speed unit rpm, uye p ndiyo nhamba yemapole pair.Kana iyo mota ichichengeta 1000 revolutions, n yakaenzana ne1000.

Ikozvino kune algorithm inonzi mota parameter identification. Uku kushandisa algorithm kugonesa mutongi wemota kuti ave nebvunzo basa remultimeter kana bhiriji, uyezve inyaya yekuyera uye kuverenga. Iyo parameter yekuzivikanwa ichatsanangurwa zvakadzama maererano nemafomu akakodzera gare gare.

Nzira yekuyera sei iwo ekutanga parameters emota?
