Ma motors osinthika amakayika ali ndi mikhalidwe iwiri yoyambira: 1) Kusintha, ma motors osinthika amayenera kugwira ntchito mosalekeza; 2) Ma motors osinthika omwe amakankhira amakhala ndi ma motors omwe amasinthasintha mosiyanasiyana. Mfundo yake yomanga ndi yakuti pamene rotor ikuzungulira, kusafuna kwa maginito kuyenera kusintha momwe zingathere. M'malo mwake, maginito okhazikika omwe amaphatikizidwa mu rotor ya mota wamba wamba wokhazikika wa maginito adzachititsanso kusintha kwa kusafuna kwa mzati wa rotor, kotero kuti makokedwe a maginito okhazikika amaphatikizanso ndi torque yakusafuna.
Kusintha kwa injini zokayikakukhala ndi zinthu ziwiri zofunika: 1) Kusintha, kusinthasintha kwa injini zokayika zimayenera kugwira ntchito mosalekeza kusintha; 2) Ma motors osinthika omwe amakankhira amakhala ndi ma motors omwe amasinthasintha mosiyanasiyana.Mfundo yake yomanga ndi yakuti pamene rotor ikuzungulira, kukayikira kwa maginito a maginito kuyenera kusintha momwe angathere.M'malo mwake, maginito okhazikika omwe amaphatikizidwa mu rotor ya mota wamba wamba wokhazikika wa maginito adzachititsanso kusintha kwa kusafuna kwa mzati wa rotor, kotero kuti makokedwe a maginito okhazikika amaphatikizanso ndi torque yakusafuna.
1. Kapangidwe ka Ontology
Mitengo yowoneka bwino ya stator ndi rotor ya motor relucance motor imapangidwa ndi zitsulo wamba za silicon.Njira yopangira izi imachepetsa kuwonongeka kwa eddy current ndi hysteresis mu mota.Palibe ma windings kapena maginito okhazikika pamitengo ya rotor, kapena ma commutators, mphete zolowera, etc.Mizati ya stator imavulazidwa ndi ma windings okhazikika, ndipo maulendo awiri otsutsana ndi ma radially amalumikizidwa mndandanda kuti apange gawo, ndipo mawonekedwe onse a galimotoyo ndi osavuta.
Ma motors osinthika osinthika amatha kupangidwa ndi magawo osiyanasiyana momwe amafunikira.Malinga ndi gawoli, lagawidwa kukhala limodzi, magawo awiri, magawo atatu, magawo anayi ndi ma multi-phase kusafuna magalimoto.Komabe, ma motors osafuna osinthika omwe ali pansi pa magawo atatu nthawi zambiri sakhala ndi mwayi woyambira okha.Magawo ochulukira omwe injini imakhala nawo, m'pamenenso masitepe ang'onoang'ono, omwe amathandizira kuchepetsa kuthamanga kwa torque.Komabe, kuchuluka kwa magawo, zida zosinthira zambiri zimagwiritsidwa ntchito, momwe zimakhalira zovuta kwambiri, ndipo mtengo wofananira udzawonjezeka.Ma motors a magawo atatu ndi anayi amagwiritsidwa ntchito masiku ano.Chiwerengero cha mitengo ya stator ndi rotor ndi yosiyana. Mwachitsanzo, magawo atatu osinthika amakayika magalimoto ali ndi mawonekedwe a 6/4 ndi mawonekedwe a 12/8, ndipo ma motors ambiri omwe ali ndi magawo anayi ali ndi 8/6.
2. Mfundo yogwira ntchito
Galimoto yamagetsi yosinthikandi injini yomwe imagwiritsa ntchito kusafuna kofanana kwa rotor kuti ipange torque, yomwe imadziwikanso kuti motor synchronous motor.Mapangidwe ake ndi mfundo zake zogwirira ntchito ndizosiyana kwambiri ndi ma mota amtundu wa AC ndi ma DC motors.Sizidalira kuyanjana kwa maginito kuchokera ku mafunde a stator ndi rotor kuti apange torque.
3. Makhalidwe a Anasintha Kukana Motor
M'zaka 20 zapitazi, ma motors osafuna kusintha akhala akuperekedwa chidwi kwambiri ndi anthu.Ndi chifukwa chakuti ali ndi makhalidwe odziwikiratu kuti ubwino wake ndi zovuta zake ndizodziwika bwino.Tiyeni tikambirane ubwino wake choyamba.
1. Makina osunthika osunthika amakhala ndi mphamvu zambiri komanso mphamvu zopulumutsa mphamvu: pamayendedwe osiyanasiyana othamanga ndi mphamvu, makina osunthika osunthika nthawi zambiri amakhala aluso kuposa asynchronous motor variable frequency frequency regulation system, ndipo magwiridwe ake amatha kukhala apamwamba. kuposa 10 pa liwiro lotsika kapena katundu wopepuka. %; Poyerekeza ndi machitidwe monga gear motor deceleration, secondary pulley deceleration.
2. Galimoto imatha kuyambika ndikuyimitsidwa pafupipafupi, ndipo kuzungulira kwa kutsogolo ndi kumbuyo kumachitika pafupipafupi: kuwongolera magwiridwe antchito a magawo anayi aanasintha kukana injiniimasinthasintha. Pamene pali mabuleki unit ndi braking mphamvu akwaniritsa zofunika, kusinthana kwa chiyambi-kuyimitsidwa ndi kutsogolo ndi m'mbuyo kasinthasintha akhoza kufika nthawi zambirimbiri pa ola.
3. Galimotoyo imatha kugwirabe ntchito ngati gawo latayika kapena kuchulukirachulukira: Mphamvu yamagetsi ikatha kapena gawo lililonse lagalimoto kapena chowongolera ikalephera, mphamvu yotulutsa yamoto yosinthika imatha kuchepetsedwa, koma imathabe. thamanga.Dongosolo likapitilira kuchuluka kwake kopitilira 120%, liwiro lidzangotsika, ndipo mota ndi wowongolera sizidzawotchedwa.
