Commutator yog dab tsi: Kev tsim kho thiab nws daim ntawv thov

Covcommuatortuaj yeem txhais tau tias yog ib qho hluav taws xob hloov pauv hauv ib hom generators thiab motors. Qhov no feem ntau yog siv los hloov cov kev taw qhia ntawm tam sim no ntawm sab nraud Circuit Court & rotor. Nws muaj xws li ib lub tog raj kheej nrog ntau cov hlau tiv tauj ntu ntawm lub tshuab tig rov qab ntawm lub tshuab. Cov txhuam hniav los yog hluav taws xob tiv tauj yog tsim los ntawm cov khoom siv carbon xovxwm ntawm ib sab ntawm lub commutator, tsim kev sib tiv tauj los ntawm cov ntu sib law liag ntawm lub commutator thaum nws tig mus. Lub armature windings yog sib koom ua ke rau ntu ntawm lubcommuator.

Cov kev siv ntawm commutators muaj xws li DC (ncaj qha tam sim no) tshuab xws li DC generators, ntau DC motors, thiab universal motors. Hauv DC lub cev muaj zog, lub commutator muab hluav taws xob tam sim no rau cov windings. Los ntawm kev hloov cov kev taw qhia ntawm tam sim no nyob rau hauv lub revolving windings txhua ib nrab tig, ib tug torque (stead revolving force) yuav raug tsim.

CommutatorKev tsim kho thiab ua haujlwm

Kev tsim kho thiab kev ua haujlwm ntawm acommuatoryog, lub commutator tuaj yeem ua tau nrog cov kab sib txuas uas tau teeb tsa rau lub kiv puag ncig ntawm lub tshuab DC, thiab sib koom ua ke rau armature windings. Thaum tus ncej tig, lub commutator yuav thim rov qab cov dej ntws tam sim no nyob rau hauv ib qho winding. Rau ib qho tshwj xeeb armature winding, thaum lub ncej tau ua tiav ib nrab tig, ces cov winding yuav txuas nrog kom cov khoom siv tam sim no los ntawm nws nyob rau hauv qhov thim rov qab ntawm thawj cov kev taw qhia.

Nyob rau hauv DC lub cev muaj zog, lub armature tam sim no ua rau lub teeb magnetic teb siv lub zog rotating, txwv tsis pub lub torque hla lub winding rau nws revolve. Hauv DC lub tshuab hluav taws xob, lub tshuab hluav taws xob tuaj yeem siv tau rau hauv kev taw qhia ntawm lub ncej kom tswj tau lub armature winding motion ntawm qhov chaw ruaj khov magnetic teb, stimulating ib tug tam sim no nyob rau hauv lub winding. Hauv ob qhov xwm txheej no, Qee zaum, cov commutators yuav thim rov qab cov kev taw qhia ntawm cov dej ntws tam sim no thoob plaws hauv lub winding kom cov ntws ntawm tam sim no nyob rau hauv Circuit Court uas yog sab nraud rau lub tshuab tswj nyob rau hauv ib qho kev taw qhia xwb.
