Switched reluctance lub cev muaj zog yog ib tug ceev tswj lub cev muaj zog tsim tom qab DC lub cev muaj zog thiab brushless DC lub cev muaj zog, thiab yog dav siv nyob rau hauv cov khoom siv hauv tsev, aviation, aerospace, electronics, machinery thiab hluav taws xob tsheb. Lub cev muaj zog hloov tsis kam muaj cov qauv yooj yim; lub cev muaj zog muaj cov qauv yooj yim thiab tus nqi qis, thiab tuaj yeem siv rau kev ua haujlwm siab. Cov qauv ntawm lub cev hloov pauv tsis txaus ntseeg yog yooj yim dua li ntawm squirrel-cage induction motor. Nws lub rotor muaj lub zog txhua yam thiab tuaj yeem siv rau kev ua haujlwm siab (xws li kaum tawm txhiab tus kiv puag ncig ib feeb).
Switched tsis kam lub cev muaj zogyog lub tshuab ceev tswj tau tsim tom qab DC lub cev muaj zog thiab tsis muaj DC lub cev muaj zog, thiab siv dav hauv cov khoom siv hauv tsev, aviation, aerospace, electronics, machinery thiab hluav taws xob tsheb.
Cov yam ntxwv tseem ceeb ntawm kev hloov tsis kam lub cev muaj zog tswj qhov system:
Cov qauv yooj yim; lub cev muaj zog muaj cov qauv yooj yim thiab tus nqi qis, thiab tuaj yeem siv rau kev ua haujlwm siab. Cov qauv ntawm lub cev hloov pauv tsis txaus ntseeg yog yooj yim dua li ntawm squirrel-cage induction motor. Nws lub rotor muaj lub zog txhua yam thiab tuaj yeem siv rau kev ua haujlwm siab (xws li kaum tawm txhiab tus kiv puag ncig ib feeb). Raws li rau stator, nws tsuas muaj ob peb lub ntsiab lus windings, yog li nws yog ib qho yooj yim los tsim thiab cov qauv rwb thaiv tsev yog yooj yim.
Circuit Court kev cia siab ntawm lub switched reluctance motor; lub hwj chim Circuit Court yog yooj yim thiab txhim khu kev qha. Txij li thaum lub cev muaj zog torque kev taw qhia tsis muaj dab tsi cuam tshuam nrog cov kev taw qhia winding tam sim no, uas yog, tsuas yog ib theem winding tam sim no yuav tsum tau, lub zog hluav taws xob tuaj yeem paub txog ib lub zog hloov ib theem. Piv rau asynchronous lub cev muaj zog windings uas yuav tsum tau bidirectional tam sim no, lub PWM inverter fais fab Circuit Court uas muab lawv yuav tsum tau ob lub hwj chim pab kiag li lawm ib theem. Yog li ntawd, qhov hloov pauv tsis txaus siab lub cev muaj zog tswj qhov system yuav tsum muaj cov khoom siv hluav taws xob tsawg dua thiab cov qauv hluav taws xob yooj yim dua li cov pulse width modulation inverter fais fab mov Circuit Court. Tsis tas li ntawd, nyob rau hauv lub hwj chim Circuit Court ntawm PWM inverter, ob lub hwj chim hloov raj nyob rau hauv txhua tus choj caj npab ncaj qha mus rau sab DC fais fab mov, uas yuav ua rau ib tug luv luv Circuit Court hlawv tawm lub hwj chim ntaus ntawv. Txawm li cas los xij, txhua lub zog hloov hluav taws xob hauv qhov hloov pauv tsis txaus siab lub cev muaj zog tswj kev sib txuas ncaj qha rau hauv series nrog lub cev muaj zog winding, uas ua rau tsis muaj qhov tshwm sim ntawm ncaj qha los ntawm luv luv Circuit Court. Yog li ntawd, kev tiv thaiv Circuit Court ntawm lub hwj chim mov Circuit Court nyob rau hauv lub ceev tswj system ntawm switched reluctance lub cev muaj zog yuav ua tau yooj yim, tus nqi yog txo, thiab kev ntseeg siab yog siab.
