How to measure the basic parameters of the motor?

Iyo tubonye moteri mumaboko yacu, niba dushaka kuyiyobora, dukeneye kumenya ibipimo byibanze.Ibipimo fatizo bizakoreshwa muri 2, 3, 6, na 10 mumashusho hepfo.Kubyimpamvu ibyo bipimo bikoreshwa, tuzasobanura birambuye mugihe dutangiye gukurura formula.Ndagira ngo mbabwire ko nanga formulaire cyane, ariko sinshobora gukora nta formulaire.Ibyo tuganira muriyi ngingo nuburyo bwo guhuza inyenyeri ya moteri.

Amafaranga yo kurwanya icyiciro

Ibipimo by'ibi bipimo biroroshye.Koresha multimeter mukiganza cyawe kugirango upime guhangana hagati yibyiciro bibiri, hanyuma ubigabanye na 2 kugirango ubone icyiciro cyo kurwanya amafaranga ya moteri.

Umubare wibiti bibiri n

Iki gipimo gisaba amashanyarazi yagenwe kugarukira.Koresha imbaraga mubyiciro bibiri byose byicyiciro cya gatatu cyicyuma cya moteri mukiganza cyawe.Ibiriho bigomba kugarukira ni 1A, na voltage igomba kunyuramo ni V = 1 * amafaranga (ibipimo byapimwe hejuru).Noneho hindura rotor ukoresheje intoki, uzumva urwanya.Niba kurwanya bitagaragara, urashobora gukomeza kongera imbaraga za voltage kugeza igihe hazaba hagaragara kuzunguruka.Iyo moteri izunguruka uruziga rumwe, umubare wimyanya ihamye ya rotor numubare wibiti bibiri bya moteri.

Ls stator inductance

Ibi bisaba gukoresha ikiraro kugirango ugerageze inductance hagati yicyiciro icyo aricyo cyose cya stator, kandi agaciro kabonetse kagabanijwe na 2 kugirango ubone Ls.

Inyuma EMF Ke

Kuri gahunda yo kugenzura FOC, ibipimo bike bijyanye na moteri birahagije.Niba kwigana matlab bisabwa, imbaraga za moteri yinyuma ya moteri nayo irakenewe.Ibipimo byo gupima ni bike cyane bitera ibibazo.Birakenewe guhagarika moteri kuri n revolisiyo, hanyuma ukoreshe oscilloscope kugirango upime voltage yibyiciro bitatu nyuma yimodoka ya moteri ihagaze neza, nkuko bigaragara mumashusho hepfo:

Muri formula yavuzwe haruguru, Vpp nigiciro cya volt hagati yimpinga nigitereko cyumurongo.

Aho Te = 60 / (n * p), n nigice cya mashini yihuta rpm, na p numubare wibiti byombi.Niba moteri ikomeza impinduramatwara 1000, n ingana na 1000.

Noneho hariho algorithm yitwa moteri yerekana moteri.Ibi ni ugukoresha algorithm kugirango ushoboze kugenzura moteri kugira imikorere yikizamini cya multimeter cyangwa ikiraro, hanyuma ni ikibazo cyo gupima no kubara.Kumenyekanisha ibipimo bizasobanurwa muburyo burambuye kubyerekeranye na formulaire nyuma.
