Switchched relucance motor ndi mota yoyendetsedwa mwachangu yomwe imapangidwa pambuyo pa DC motor ndi brushless DC motor, ndipo imagwiritsidwa ntchito kwambiri pazida zapakhomo, ndege, zakuthambo, zamagetsi, makina ndi magalimoto amagetsi.The switched kusafuna galimoto ali ndi dongosolo losavuta;galimotoyo ili ndi dongosolo losavuta komanso lotsika mtengo, ndipo lingagwiritsidwe ntchito pa ntchito yothamanga kwambiri.Kapangidwe ka injini yosinthira kukana ndiyosavuta kuposa ya gologolo-cage induction motor.Rotor yake imakhala ndi mphamvu zamakina kwambiri ndipo imatha kugwiritsidwa ntchito mwachangu (monga masauzande masauzande osinthika pamphindi).
Anasintha kukana injinindi mota yoyendetsedwa ndi liwiro lopangidwa pambuyo pa DC motor ndi brushless DC motor, ndipo imagwiritsidwa ntchito kwambiri pazida zapakhomo, ndege, ndege, zamagetsi, makina ndi magalimoto amagetsi.
Zofunika zazikulu za switch relucance motor speed control system:
Kapangidwe kosavuta;injiniyo ili ndi mawonekedwe osavuta komanso otsika mtengo, ndipo imatha kugwiritsidwa ntchito mwachangu kwambiri.Kapangidwe ka injini yosinthira kukana ndiyosavuta kuposa ya gologolo-cage induction motor.Rotor yake imakhala ndi mphamvu zamakina kwambiri ndipo imatha kugwiritsidwa ntchito mwachangu (monga masauzande masauzande osinthika pamphindi).Ponena za stator, ili ndi ma windings ochepa okha, kotero n'zosavuta kupanga ndipo mapangidwe otsekemera ndi osavuta.
The dera kudalirika kwa anazimitsa kukana galimoto;dera lamagetsi ndi losavuta komanso lodalirika.Popeza mayendedwe amakokedwe a mota alibe chochita ndi komwe amakhotakhota pano, ndiye kuti, gawo limodzi lokha lopindika lomwe limafunikira, gawo lamagetsi limatha kuzindikira kusintha kwamagetsi kumodzi pagawo lililonse.Poyerekeza ndi ma asynchronous motor windings omwe amafunikira bidirectional current, PWM inverter power circuit yomwe imawapatsa imafunikira zida ziwiri zamagetsi pagawo lililonse.Chifukwa chake, makina osinthira kuthamanga kwagalimoto amafunikira magawo ochepa amagetsi komanso mawonekedwe osavuta ozungulira kuposa ma pulse wide modulation inverter magetsi.Kuphatikiza apo, mumayendedwe amagetsi a inverter ya PWM, machubu awiri osinthira magetsi mumkono uliwonse wa mlatho amayenda molunjika mbali yamagetsi ya DC, zomwe zitha kuchititsa kuti dera lalifupi liwotche chipangizo chamagetsi.Komabe, chipangizo chilichonse chosinthira mphamvu pamakina owongolera kuthamanga kwagalimoto chimalumikizidwa mwachindunji ndi mafunde agalimoto, omwe amapewa kwambiri zomwe zimachitika mowongoka.Chifukwa chake, gawo lachitetezo cha gawo loperekera mphamvu pamakina owongolera liwiro la injini yosinthira kukana kutha kusinthidwa, mtengo wake umachepetsedwa, ndipo kudalirika ndikokwera.
