Lamulo la kumanzere, lamanja lamanja, lamanja la screw screw.Lamulo la kumanzere, ili ndilo maziko a kusanthula mphamvu ya kayendedwe ka galimoto.Mwachidule, ndi kondakitala wonyamula pakali pano mu mphamvu ya maginito, yomwe idzakhudzidwa ndi mphamvu.

Lolani mzere wa maginito udutse kutsogolo kwa kanjedza, mayendedwe a zala ndi njira yapano, ndipo mayendedwe a chala chachikulu ndi njira ya mphamvu ya maginito.Kukoka kwa mphamvuyi kumadula mizere ya maginito kuti apange mphamvu ya electromotive.

Lolani mzere wa maginito udutse m'manja, mayendedwe a chala chachikulu ndikuwongolera, ndipo chala chake ndikuwongolera mphamvu yopangidwa ndi electromotive.N'chifukwa chiyani kulankhula za mphamvu electromotive mphamvu?Sindikudziwa ngati muli ndi chokumana nacho chofanana ndi ichi.Mukaphatikiza mawaya agawo atatu agalimoto ndikutembenuza mota ndi dzanja, mudzapeza kuti kukana kuli kwakukulu kwambiri.Izi ndichifukwa choti kulowetsedwa kumachitika panthawi yozungulira motere.Mphamvu ya electromotive imapanga zamakono, ndipo zamakono zomwe zikuyenda kupyolera mu kondakitala mu mphamvu ya maginito zidzapanga mphamvu yotsutsana ndi njira yozungulira, ndipo aliyense adzamva kuti pali kukana kwakukulu kwa kuzungulira.

Mawaya agawo atatu amasiyanitsidwa ndipo mota imatha kutembenuzika mosavuta

Mizere ya magawo atatu imaphatikizidwa, ndipo kukana kwa galimoto kumakhala kwakukulu kwambiri.Malinga ndi lamulo la wononga lamanja, gwirani solenoid yopatsa mphamvu ndi dzanja lamanja, kuti zala zinayi zikhomedwe mofanana ndi momwe zilili panopa, ndiye kuti mapeto omwe atchulidwa ndi chala chachikulu ndi N mzati wa solenoid yolimbikitsidwa.

Lamulo ili ndilo maziko a kuweruza polarity ya koyilo yamphamvu, ndipo mayendedwe a muvi wofiira ndi njira yamakono.Titawerenga malamulo atatuwa, tiyeni tione mfundo zazikulu za kasinthasintha wa galimoto.Gawo loyamba: Mtundu wamagalimoto a DC Timapeza mtundu wa mota ya DC yomwe idaphunziridwa mufizikiki yakusukulu yasekondale, ndikuwunika kosavuta kudzera mu njira yowunikira maginito.

State 1 Ikagwiritsidwa ntchito pamakoyilo kumapeto onse awiri, molingana ndi lamulo la screw lamanja, mphamvu ya maginito yogwiritsira ntchito maginito B (monga muvi wandiweyani) imapangidwa, ndipo chozungulira chapakati chidzayesa kupanga. mayendedwe ake amkati maginito induction mzere momwe angathere.Mayendedwe a mzere wakunja wa maginito amasinthasintha kuti apange kachidutswa kakang'ono kotseka maginito, kuti chozungulira chamkati chizizungulira mozungulira.Pamene mayendedwe a rotor magnetic field ali perpendicular kwa njira ya kunja kwa maginito, torque yozungulira ya rotor ndiyo yaikulu kwambiri.Zindikirani kuti "mphindi" imanenedwa kuti ndiyo yaikulu kwambiri, osati "mphamvu".Ndizowona kuti pamene maginito a rotor ali kumbali yofanana ndi mphamvu ya maginito yakunja, mphamvu ya maginito pa rotor ndi yaikulu kwambiri, koma panthawiyi rotor ili pamtunda wopingasa ndipo mkono wa mphamvu ndi 0, ndi wa ndithudi sichizungulira.Kuwonjezera apo, nthawiyi ndi yopangidwa ndi mphamvu ndi mkono wa mphamvu.Ngati mmodzi wa iwo ndi ziro, mankhwala ndi ziro.Pamene rotor imatembenukira kumalo opingasa, ngakhale kuti sichimakhudzidwanso ndi torque yozungulira, idzapitirizabe kuyendayenda mozungulira chifukwa cha inertia.Panthawiyi, ngati njira yamakono ya solenoids iwiri yasinthidwa, monga momwe tawonetsera mu chithunzi pansipa, rotor idzapitirizabe kuzungulira.pita kutsogolo molunjika,

M'chigawo cha 2, njira zamakono za solenoids ziwiri zimasinthidwa nthawi zonse, ndipo rotor yamkati idzapitirizabe kuzungulira.Kusintha kumeneku komwe kumayendera kumatchedwa commutation.Cholemba cham'mbali: Nthawi yoti muyende imangogwirizana ndi malo a rotor osati mwachindunji ndi kuchuluka kwina kulikonse.Gawo 2: Galimoto yozungulira ya magawo atatu yamitundu iwiri ya stator Nthawi zambiri, makhondedwe a magawo atatu a stator amakhala ndi njira yolumikizira nyenyezi ndi njira yolumikizira ma delta, ndipo "mawotchi awiri ndi awiri olumikizira nyenyezi ya magawo atatu" ndiyomwe imakonda kwambiri. zomwe zimagwiritsidwa ntchito pano.Chitsanzochi chimagwiritsidwa ntchito pofufuza mosavuta.

Chithunzi pamwambapa chikuwonetsa momwe ma stator windings amalumikizidwe (wozungulira sawonetsedwa ngati maginito ongoyerekeza amitundu iwiri), ndipo maginito atatu amalumikizidwa palimodzi mu mawonekedwe a "Y" kudzera pakatikati.Galimoto yonse imatsogolera ku mawaya atatu A, B, C. Akapatsidwa mphamvu ziwiri ndi ziwiri, pali zochitika 6, zomwe ndi AB, AC, BC, BA, CA, CB.Dziwani kuti izi zili bwino.

Tsopano ndikuyang'ana gawo loyamba: gawo la AB ndilopatsidwa mphamvu

Gawo la AB likapatsidwa mphamvu, mayendedwe a maginito opangidwa ndi A pole coil akuwonetsedwa ndi muvi wofiyira, ndipo mayendedwe a mzere wa maginito opangidwa ndi B pole akuwonetsedwa ndi muvi wabuluu, kenako mayendedwe. za mphamvu zotsatira zikuwonetsedwa ndi muvi wobiriwira, ndiye Poganiza kuti pali maginito awiri-pole, njira ya N-pole idzagwirizana ndi njira yomwe ikuwonetsedwa ndi muvi wobiriwira molingana ndi "wozungulira pakati adzayesa kusunga kulunjika kwa mizere yake yamkati ya maginito yogwirizana ndi mizere yakunja ya maginito ".Ponena za C, alibe chochita naye pakadali pano.

Gawo 2: Gawo la AC Lopatsidwa Mphamvu

Gawo lachitatu: BC gawo lamagetsi

Gawo lachitatu: Gawo la BA limapatsidwa mphamvu

Zotsatirazi ndi chithunzi cha maginito apakatikati (rota): rotor iliyonse imazungulira madigiri 60.

Kuzungulira kokwanira kumatsirizika munjira zisanu ndi chimodzi, zomwe zisanu ndi chimodzi zimasinthidwa.Gawo lachitatu: magawo atatu ozungulira ma multi-pole inner rotor motor Tiyeni tiwone mfundo yovuta kwambiri.Chithunzi (a) ndi gawo lachitatu-magawo asanu ndi anayi okhotakhota asanu ndi limodzi (magawo atatu, matembenuzidwe asanu ndi anayi, asanu ndi limodzi).Mosiyana ndi pole) injini yamkati ya rotor, kulumikizana kwake kokhotakhota kukuwonetsedwa pachithunzi (b).Zitha kuwoneka kuchokera ku Chithunzi (b) kuti maulendo a magawo atatu amalumikizananso palimodzi pamalo apakati, omwenso ndi nyenyezi.Nthawi zambiri, kuchuluka kwa ma windings a injini sikumagwirizana ndi kuchuluka kwa mitengo ya maginito okhazikika (mwachitsanzo, ma windings 9 ndi mizati 6 amagwiritsidwa ntchito m'malo mwa ma windings 6 ndi mitengo 6), kuti ateteze mano a stator ndi maginito a rotor kuti asakope ndi kugwirizanitsa.

Mfundo ya kayendedwe kake ndi: N mzati wa rotor ndi S mzati wa mafunde amphamvu amakhala ndi chizolowezi chogwirizanitsa, ndi S pole ya rotor ndi N mzati wa mafunde amphamvu amakhala ndi chizolowezi chogwirizanitsa.Ndiko kuti, S ndi N amakopana.Dziwani kuti ndizosiyana ndi njira yowunikira yapitayi.Chabwino, tiyeni tikuthandizeni kusanthulanso.Gawo loyamba: Gawo la AB ndi magetsi

Gawo 2: Gawo la AC Lopatsidwa Mphamvu

Gawo lachitatu: BC gawo lamagetsi
