Kupita patsogolo, potengera izi, mutha kuganiza za kupita patsogolo kopeza ziphaso zamaluso, monga CET-4 ndi CET-6.Mu injini, injini imakhalanso ndi magawo.Zotsatizana pano sizikutanthauza kutalika kwa injini, koma kuthamanga kwa injini.Tiyeni titenge gawo la 4 mota ngati chitsanzo kuti tiwone tanthauzo lenileni la mndandanda wamagalimoto.
Level 4 motor imatanthawuza 1-minute synchronous speed of motor = {mafupipafupi amagetsi (50Hz) × masekondi 60} ÷ (magawo amoto ÷ 2) =3000 ÷ 2 = 1500 revolutions.Mu fakitale, nthawi zambiri timamva kuti injiniyo ili ndi magawo angapo.Kuti timvetsetse, choyamba tiyenera kudziwa lingaliro la mzati: mzati umatanthawuza mtengo wa maginito wopangidwa ndi rotor ya jenereta pambuyo poti chisangalalo chimagwiritsidwa ntchito pa koyilo ya rotor.Mwachidule, zikutanthawuza kuti kusintha kulikonse kwa rotor kungapangitse maulendo angapo amakono panthawi imodzi ya koyilo ya stator.Ndikofunikira kupanga kuthekera kwa 50Hz ngati kuchuluka kwa mizati kuli kosiyana Kuthamanga kosiyana kumafunika.50Hz, 60 masekondi ndi mphindi (ie 3000) ogaŵikana ndi chiwerengero cha mizati ndi chiwerengero cha kusintha injini pa mphindi.N'chimodzimodzinso ndi injini, yomwe ndi njira yosiyana ya jenereta.
Chiwerengero cha mizati chimasonyeza liwiro synchronous injini.Liwiro la 2-pole synchronous ndi 3000rmin, liwiro la 4-pole synchronous ndi 1500rmin, liwiro la 6-pole synchronous ndi 1000rmin, ndipo liwiro la 8-pole synchronous ndi 750rmin.Zitha kumveka kuti 2-pole ndi nambala yoyambira (3000), mitengo ya 4 imatha kugawidwa mu 2, mitengo 6 ikhoza kugawidwa mu 3, ndipo mitengo ya 8 ikhoza kugawidwa mu 4. M'malo mwa mitengo 2, 3000 iyenera kugwiritsidwa ntchito kuchotsa 2. Kuchuluka kwa mizati ya galimotoyo, kutsika kwa liwiro la galimotoyo, koma ndikokulirapo;posankha mota, muyenera kuganizira za torque yoyambira yomwe ikufunika ndi katundu.Mwachitsanzo, torque yofunikira poyambira ndi katundu ndi yayikulu kuposa yoyambira yopanda katundu.Ngati kuyambika kwamphamvu komanso kulemedwa kolemetsa, Kuyambira pansi (kapena kuyambika kwa nyenyezi) kudzaganiziridwanso;ponena za liwiro lofananira ndi katundu mutazindikira kuchuluka kwa mizati yagalimoto, imatha kuganiziridwa kuti imayendetsa ndi lamba wamitundu yosiyanasiyana kapena magiya othamanga (Gearbox) Ngati mphamvu zonyamula katundu sizingakwaniritsidwe mutazindikira. chiwerengero cha mizati ya galimoto kudzera lamba kapena kufala kwa zida, mphamvu yogwiritsira ntchito galimoto iyenera kuganiziridwa.
Magawo atatu a AC motor amapangidwa makamaka ndi stator ndi rotor.Pamene magawo atatu a AC alumikizidwa ndi stator, mphamvu ya maginito yozungulira idzapangidwa.Mphamvu ya maginito nthawi zonse imakhala ndi mitengo iwiri (ikhozanso kunenedwa kuti ikuwoneka pawiri), yomwe ndi N pole (North Pole) ndi S pole (south pole) , yomwe imadziwikanso kuti counter pole.Pamene mapiringidzo amachitidwe a AC motor stator mapindikidwe ndi osiyana, chiwerengero cha mizati maginito wa kasinthasintha maginito munda ndi osiyana.Kuchuluka kwa mitengo ya maginito kumakhudza mwachindunji liwiro la mota, ndipo ubale wawo ndi: liwiro lolumikizana = 60 × pafupipafupi mulingo wa logarithm.Ngati liwiro la synchronous la injini ndi 1500 rpm, tikhoza kuwerengera kuti logarithm yamtengo ndi 2, ndiko kuti, injini ya 4-pole molingana ndi ndondomeko yomwe ili pamwambapa.Liwiro la synchronous ndi pole logarithm ndiye magawo oyambira agalimoto, omwe amapezeka pamiyala yamoto.Chifukwa pole logarithm imatha kukhudza kuthamanga kwa mota, liwiro la mota limatha kusinthidwa posintha logarithm yamoto.
Kwa katundu wamadzimadzi monga mafani ndi mapampu, katundu wamtunduwu amakhala ndi mawonekedwe odziwika.Mwambiwu umatchedwa kukana kusintha, kutanthauza kuti katundu wamtunduwu amakhala ndi kukana kwakukulu kwa kusintha kwazomwe zikuchitika.Ngakhale kuti torque yomwe ikufunika kulimbikitsa kusintha kwa katundu wamtunduwu siwokwera, imafunika mphamvu zambiri kuti isinthe momwe zinthu zilili panopa.Zili ngati madzi otentha.Moto wawung'ono ukhozanso kuwira, ndipo uyenera kukhala Udzawira posachedwa, ndipo moto umene ungafunike udzakhala waukulu kwambiri.
Awa ndi mafotokozedwe enieni a mndandanda wamagalimoto.Kwa mafupipafupi omwe aperekedwa komanso poyambira pano, palibe ubale wosalephereka pakati pawo.Zomwe zimayambira zimatengera kukhazikitsidwa kwa VF curve komanso kutalika kwa nthawi yothamangitsa.Pazinthu zamadzimadzi, kugwiritsa ntchito mphamvu zambiri zokhotakhota kumapangitsa kuti zida zizitha kupulumutsa mphamvu zambiri komanso kupeza phindu lazachuma.
